Connection terminal for fiber optic cables
The present invention relates, in general, to communication networks and, more particularly, to fiber connection terminals for use in optical communication networks.
Residential, corporate, governmental, educational and institutional users of communications services may want high-bandwidth connections to a communications network in order to send and receive data at high transmission speeds. High bandwidth communications can allow users to take advantage of advanced communications capabilities, such as voice over Internet protocol (VoIP) communications, interactive games, high resolution video delivery, such as high definition television (HDTV) as well as the transmission and / or reception of large data files.
Communications service providers, such as telephone companies, cable television companies, etc., may understand that customers want these high-bandwidth applications and / or services at a reasonable cost. Previous attempts to provide high-bandwidth communications channels have included techniques such as integrated services digital network (ISDN), digital subscriber line (DSL), asynchronous digital subscriber line (ADSL) and coaxial cable television cable . Technologies such as the above can provide broadband capabilities to a certain extent. As an example, some DSL services can provide up to approximately 5 Mbits / second of data. Users can, however, demand even higher bandwidths. Previous technologies may have inappropriate bandwidth for some users and / or these technologies may be relatively expensive for deployment and / or maintenance.
The demand for higher bandwidth services, by way of example, in the order of magnitude of up to 500 Mbits / second or even greater, can make service providers look for more advanced technologies. One such technology is referred to as passive optical networks (PONS). PONS networks can use optical fibers deployed between a central office of the service provider, or header end, and one or more end-user facilities. A service provider may use a central office, or head end, that contains electronic equipment to place signals on optical fibers that are connected to users' facilities. End user installations can use equipment to receive optical signals from the optical fibers. In PONS networks, the central office, or the header end, the transmission equipment and / or the transmission equipment located in the end-user facilities may, respectively, use a laser to inject data into a fiber in a manner that may not require the use of any active components, such as amplifiers between the head office, or the header end, and / or end-user facilities. In other words, only passive optical components, such as splitters, optical fibers, connectors and / or splices, can be used between a service provider and an end-user installation in the PONS network. The PONS network may be attractive to service providers because passive networks may be less expensive to maintain and / or operate compared to active optical networks and / or older copper-based networks such as a public switched telephone network (PSTN ). In addition to the possibility of being less expensive than other network topologies, PONS networks can provide sufficient bandwidth to meet most of the foreseeable high-bandwidth communications needs of future users.
In PONS networks, the transmission equipment can transmit signals containing voice, data and / or video through a strand of fibers to the facilities. An optical fiber can be divided using, for example, passive optical splitters, so that the signals are dispersed from one fiber (the input fiber) to multiple output fibers that are installed, by way of example, to the establishments of users from a point of convergence in the network. An optical fiber routed to a user's premises can be routed through a fiber connection terminal en route to the facilities. In the fiber connection terminal, the signals that appear in one or more optical fibers can be routed to one or more end-user installations. The fiber connection terminals may be mounted in aerial applications, such as near the tops of utility poles, along multi-conductor and / or multi-fiber copper strands suspended between the utility poles. Fiber connection terminals can also be installed in junction boxes mounted at ground level and / or vaults below ground level, where public services are installed below ground level.
Fiber connection terminals can be made of injection molded plastic to keep unit costs as low as possible. Since the fiber connection terminals may be exposed to the elements, they may be resistant to water infiltration and / or degradation due to ultraviolet (UV) light. The fiber connection terminal enclosures can be made from plastic material resistant to UV ultraviolet radiation and / or provided with gaskets to prevent water infiltration. Sometimes, the plastic material used for the enclosure can lead to fatigue and / or cracks that lead to the penetration of water and / or water vapor inside the enclosure. The design of the coincidence surfaces of the existing enclosures, such as interconnections provided with
gaskets, can interact in a way that facilitates the penetration of water and / or water vapor. By way of example, the sealing gasket material may be of an inadequate durometric characteristic to provide a seal between the body of the enclosure and / or a base of the enclosure.
The existing fiber connection terminals may not have sufficient interior space to allow the fibers, within the enclosures, to bend with a minimum radius of curvature recommended by the manufacturer and / or sector. When the optical fibers are curved with a smaller radius than the minimum recommended by the manufacturer and / or sector, such as 1.75 inches, optical signal losses may occur.
The existing fiber connection terminals may have orientations of the connectors that do not facilitate a non-bulky and / or ergonomic coupling and / or decoupling of fibers / optical connectors by service and installation personnel (hereinafter line operator). Consequently, it may be difficult for a line operator to join and / or remove connectors in some situations, such as when servicing a fiber connection terminal mounted on a utility pole using, for example, a scale and / or a forklift.
When the fiber connection terminals are deployed in the field, they may need to be tested before connecting the subscribers to the communications services provided through the fiber connection terminals. Testing may be required to confirm that the optical fibers attached to the fiber connection terminal are functioning properly and that the connectors and / or receptacles associated with the fiber connection terminal are installed and / or functioning correctly. Tests can be performed by injecting a signal into a fiber in a central office and measuring the signal with a detector in a fiber connection terminal. A line operator can inject a signal into a fiber in a central office and then move to a place that has a fiber connection terminal. The line operator can climb on a pole and connect a detector to an output receptacle at the fiber connection terminal. The line operator can determine if the signal has a desired signal to noise ratio. After performing the measurement, the line operator can return to the central office and connect the test signal to another fiber associated with the fiber connection terminal. The line operator can move back to the terminal and detect the test signal. If, for example, a fiber connection terminal has eight output receptacles, the line operator can repeat the movement to and from the connection terminal eight times. The tests of the fiber connection terminals, with the use of known techniques, can be demanding in labor and can consume a large amount of fuel due to travel from one place to another between the central office and the locations of the fiber connection terminals.

By way of example, the downstream splitter 218 may include a splitter 1x2, 1x4 and / or 1x8. The downflow divider 218 may include passive and / or active dividing devices operating alone or in combination. In one embodiment, the downflow splitter 218 can be incorporated into a fiber connection terminal 220.
The fiber connection terminal 220 may include any device capable of receiving one or more input fibers and distributing optical communication signals through the input fibers to one or more output fibers. The fiber connection terminals 220, consistent with the embodiments of the invention, are used for interconnection between distribution cables and connection cables in a PON network application. The fiber connection terminal 220 may be manufactured from an injection molded plastic material and may include an enclosure or housing body, and a base. The fiber connection terminal 220 may be configured by segmenting a multi-fiber cable at a branch or break point. By way of example, a large fiber count distribution cable can be segmented to obtain eight fibers for connection to a fiber connection terminal having eight output receptacles. A single cable, which has one or more optical fibers, can divert the splice location and serve as an input or power cable for the fiber connection terminal 220. As an example, a power cable may have a central tube that houses a plurality of individual optical fibers. Inside the fiber connection terminal 220, the multi-fiber power cable can be separated into individual fibers and then terminated in individual solid outer receptacles, connectors and / or adapters located on an outer surface of the enclosure. The fiber connection terminal 220 can thus be used to stagger the PON network cabling system near the installation sites, such as a residence 120 or an office building 122, so that when a subscriber requests the service, a simple connectorized connection cable can be connected, quickly and easily, between the fiber connection terminal 220 and a circuit switch / ONT 202 and a customer's premises.
The fiber connection terminal 220 can also be coupled to a power cable in a manufacturing or assembly facility. By way of example, the fiber connection terminal 220 may be installed in a power cable with multi-fiber strands in a predetermined location. In another embodiment, a break can be determined with an input connector in a manufacturing facility. In the field, a fiber connection terminal 220 can be attached to the input connector through an input receptacle. Embodiments of the fiber connection terminal 220 can take many forms. Several embodiments, by way of example, are described below.
The network architecture described with reference to Figures 1 and 2 may operate in a point-to-multipoint PON network configuration using, by way of example, 1:32 splitters in FDH 114 or a splitter hub 206. The network architecture can be rich in fibers, such as in a 1: 1 distribution arrangement between FDH 114 and the installation of a client, such as a residence 120 and / or the network architecture can be diluted, such as in a 1: X arrangement, where X is an integer greater than 1.

The terminal 300 consists of two molded plastic enclosure parts separated by a flexible sealing interface that operates for the tight closing of an internal cavity against the elements. By way of example, the terminal may consist of a base 302 and a housing or body 306.
The terminal 300 may include a base 302 that can be releasably attached to the housing 306 using, by way of example, fixing devices, keyed retainers, clamp devices, etc. The base 302 may include a practically flat shape configured to retain a seal and / or other sealing devices along a base mounting surface that can be releasably coupled to a corresponding housing mounting surface associated with the housing 306. The base 302 can be adapted for attachment to a surface, such as a utility pole, using fixing devices such as nails and / or screws, by means of a fixing device guide 304.
The housing 306 can be modeled to constitute a cavity to accommodate optical fibers. The housing 306 includes an outer surface that has through penetrations for receiving, by way of example, of outlet receptacles 310A-D. The housing 306 can be modeled so that an upper base surface 302 operates to constitute a closed area in conjunction with the cavity when coupled to the housing 306 along an interconnection provided with gaskets. The housing 306 may be configured so that a part of the inner cavity operates as a fiber management part 308 to store the excess optical fiber. In one embodiment, the housing 306 may be configured to have a depth 320 sufficient to allow the storage of fiber coils in an angular orientation in order to facilitate the maintenance of a given minimum radius of curvature. By way of example, the fiber management part 308 may be configured to retain fiber coils with a radius of curvature that is at least of the order of magnitude of the minimum radius of curvature recommended by the manufacturer.
PON network fiber connection terminals, similar to those shown in Figure 3A, can be used to provide a multi-fiber cable break containing, for example, 4, 6, 8 and / or 12 fibers in power adapters. solid individual outdoor connectors. The rupture of the fibers inside the terminal 300 can be done by placing curvatures in the individual fibers within the enclosure.
Terminal 300 may include an enlarged fiber management part 308. The use of an enlarged fiber management part 308 ensures that the fibers are not driven, adversely, by the interior walls of the enclosure. The expanded fiber management portion 308 allows at least one route for a fiber that meets a minimum radius of curvature recommended by the manufacturer for said fiber. A manufacturer recommended minimum, or specified, for the radius of curvature refers to a parameter spread to the sector for particular types of optical fibers. This parameter identifies a minimum recommended radius of curvature for a given fiber. If a minimum radius of curvature is exceeded, excess signal loss may occur resulting in a reduced signal to noise ratio in a receiving device. As an example, if a manufacturer specifies a minimum radius of curvature of 1.5 inches, the radius of curvature is exceeded when an optical fiber is curved so that the minimum radius of curvature is less than 1.5 inches, as would be the case if used a radius of curvature of 1.4 inches. Since the signal loss can increase exponentially when the minimum radius of curvature is exceeded, care must be taken to maintain at least the minimum specified radius of curvature.
Increased the depth 320 of the terminal 300, there is a route within the enclosure for a coil to be installed at an angle that meets the minimum radius of curvature criteria and therefore eliminates the risk of increased signal attenuation due to a bend. excessive fiber. Using fiber receiving mechanisms, such as hooks (illustrated in Figure 6), the coil can be organized and retained within a suitable radius without losing the organization of the coils. The depth 320 can be modified when necessary to achieve a desired radius of curvature for the fiber coils arranged there.
Embodiments of the terminal 300 may have the following dimensions, by way of example: for a 4-outlet enclosure, 3-inch (76.2 mm) depth x 3.6 inches (91.4 mm) width x 11.1 inches (281.9 mm) length ; for an enclosure of 6 or 8 outlets, a bottom of 3 inches (76.2 mm) x width of 3.6 inches (91.4 mm) x length of
16.6 inches (421.6 mm) and for a 12-outlet enclosure, a 3-inch bottom (76.2 mm) x a width of 3.6 inches (91.4 mm) x a length of 22.7 inches (576.6 mm).
The 310A-D output receptacles include any device capable of receiving a connector. By way of example, the output receptacle 310 can transmit optical data received through the bundle of incoming fibers 318 to an output fiber 314. By way of example, the output receptacles 310A-D can provide a solid outer packet housing a splint alignment sleeve for the purpose of matching two optical fiber connectors. The output receptacles 310 may include an optical fiber connector consisting of an SC / APC (angled internal physical contact) that is connected to a single optical fiber. The optical fiber can be tubed with a 900 μm (nine hundred micron) diameter conduit and / or color-coded tubing material to protect the waveguide part of the fiber that transmits the optical signal. The internal SC / APC connector can be removably adapted with the output connector 312. The output receptacles 310A-D can be inserted when not in use so as to prevent the accumulation of dirt and moisture in a fiber within a fiber outlet receptacle
The output connector 312 may include a modified SC / APC connector that has been reinforced to increase its durability to meet, by way of example, the demands of the outdoor environments. By way of example, the output connector 312 includes modifications to provide weather protection and UV radiation for an optical fiber inside the connector. The output connector 312 can also be adapted to increase the tensile strength of the fiber from the connector and / or connector from a receptacle to a value of 100 pounds or more. As an example, a tensile strength for an SC / APC connector can be in the order of magnitude of 3 to 4 pounds. By using embodiments of the output connector 312, the tensile strength can be significantly improved compared to that of conventional SC / APC connectors. The outlet connector 312 and the outlet receptacle 310 constitute an airtight assembly when coupled together using, by way of example, threaded sleeves. In one embodiment, the output connector 312 and / or the output receptacle 310 are provided with o-rings to provide radial closures within each receptacle when they are matched with the output connector 312. The output receptacles 310 may be also provided with one or more o-rings in the vicinity of an interface between outlet receptacles 310 and housing 306.
The incoming fiber bundle 318 may include one or more optical input fibers enclosed within a protective sheath, or tube, to couple the incoming optical signals with the output connector 312 through the output receptacle 310. By way of example, If terminal 300 includes four receptacles, the incoming fiber bundle 318 may include four optical fibers. An incoming optical fiber can be associated with a particular output receptacle. The amount of fibers within the bundle of incoming fibers 318 may coincide with the number of receptacles 310A-D, may exceed the number of receptacles 310A-D and / or may be less than the number of receptacles 310A-D. Individual optical fibers, within a bundle of incoming fibers 318, can be adapted for outdoor applications using a 900 μm tubing and / or color-coded for protection. Incoming fibers can end with an industry standard SC / APC connector.
The incoming fiber bundle 318 can enter the terminal 300 through the input channel 316. The input channel 316 can consist of a tubular passage or inlet through which the beam 318 can pass. The individual fibers can be fanned from the incoming beam once inside the internal cavity of the terminal
300. The incoming beam 318 can be sealed to the input channel 316 using, by way of example, potting adhesive injection techniques, known in this activity. The input channel 316 can be adapted to receive an input receptacle to receive incoming fibers. When the input channel 316 is adapted with a receptacle, the incoming beam 318 can be terminated with a matching input connector to couple the optical signals to the input receptacle and / or the output receptacle 310.
Figure 3B illustrates a sectional view of the embodiment, by way of example, of the housing illustrated in Figure 3A, consistent with the principles of the invention. The housing 306 can be configured with a stepped face for mounting connector receptacles. The housing 306 may include a storage cavity 330, a first stepped face 332, a first transition zone 334, a second stepped face 336, a second transition zone 338, a first interior angle 340, a second interior angle 342 and a retaining device mounting channel 344. The first applied force 346, the second applied force 348 and the third applied force 350 may represent forces associated with the mounting terminal 300.
The storage cavity 330 can occupy a part of the interior of the housing 306 and can be used to store the excess optical fiber. By way of example, the storage cavity 330 can be located in an upper part of the interior of the housing 306 and can be sized to store optical fibers in coils. Storage capacity 330 can be used to maintain excess fiber optic in an organized manner that facilitates efficient configuration and assembly of terminal 300.
The first stepped face 332 and the second stepped face 336 can be configured to receive the output receptacle 310. The first stepped face 332 and the second stepped face 336 can operate as surfaces of
output receptacle holder. The first stepped face 332 and the second stepped face 336 may be arranged with respect to the first transition zone 334 and the second transition zone 338, respectively, in order to keep the output receptacle 310 in a given relationship, or orientation , with respect to housing 306
or a mounting location, such as a utility pole. The first interior angle 340 can operate with the first stepped face 332 and the first transition zone 334 to establish the predetermined orientation for an outlet receptacle 310 installed there. The second interior angle 342 can operate with the second stepped face 336 and the second transition zone 338 to establish the predetermined orientation for an outlet receptacle 310 installed there. The predetermined orientation for the receptacles on the first stepped face 332 and the second stepped face 336 may be practically similar or may be different. By way of example, the housing 306 may be associated with the base 302 and mounted on a utility pole. It can be determined that line operators will approach housing 306 by a scale. The first stepped face 332 and the second stepped face 336 may be configured so that the receptacles mounted there are aligned to provide the line operator with ergonomic and / or easily visible access to the output receptacle 310 when an output connector 312 is attached and / or output fiber 314.
The housing 306 may include one or more retaining device mounting channels 344 to retain, in an adjustable manner, the fiber retention devices such as hooks, clamps, cable ties, etc. By way of example, the channel of the retention device 344 can facilitate a height adjustment with a fiber retention hook used to retain the excess optical fiber in the coils within the inner cavity of the housing 306.
The housing 306 may be subjected to one or more applied forces when attached to a base, such as the base 302, using joining devices, such as fixing devices. As an example, the first applied force 346, the second applied force 348 and / or the third applied force 350 may result from the attachment of the housing 306 to the base 302 using screws. The housing 306 can be adapted to reduce the detrimental effects of the applied bending forces, by way of example, by reinforcing the first inner angle 340 and / or the second inner angle 342. By way of example, the thickness of the material in the vicinity of the First inner angle 340 and / or second inner angle 342 can be increased in order to increase the rigidity of the housing 306.
Figure 4 illustrates a view of an inner cavity associated with an exemplary embodiment of a fiber connection terminal employing an angled fiber management cavity, consistent with the principles of the invention. Figure 4 illustrates the inner cavity of the stepped housing 306. The inner cavity may include a group of incoming fibers 402A-D, a first central retention device 404, a second central retention device 406, a low elevation retention device 408, fiber coils 410, a first high lift retainer 412, a second high lift retainer 414, individual fibers 402A, B, C and D, receptacle bodies 416A, B, C and D, a joint 418 shutter and 420A and 420B fiber guides.
A group of incoming fibers 402A-D may include individual fibers 402A, B, C and D may be received through the incoming fiber bundle 318. The first and second central retention devices 404 and 406 may include any device capable of retaining virtually a or more fibers in a certain place. By way of example, the first and second central retention devices 404 and 406 may releasably retain a group of incoming fibers 402A-D along a central part of the housing 306, such as along the length of the center line of the housing 306. The first and second central retention devices 404 and 406 may be held in place by adhesive and / or mechanical fastening techniques. By way of example, the first and second central retention devices 404 and 406 may employ fixing devices, releasable fingers, fiber guides, insulating tapes, hooks, channels, etc., to fix the group of incoming fibers 402A-D. Therefore, any device capable of retaining a fiber in a desired location is considered by the first and second central retention devices 404 and 406.
The excess fiber in the incoming fiber group 402A-D can be stored in one or more fiber coils 410 inside the housing 306. The fiber coils 410 can be formed in cooperation with a low lift retainer 408, a first device of high lift retention 412 and a second high lift retention device 414. The low lift retention device 408 may include any device capable of retaining one or more fibers at a particular location. The first high lift retention device 412 and the second high lift retention device 414 may include any device capable of retaining one or more optical fibers at a particular location with respect, by way of example, a low lift retention device 408. By way of example, a relationship between the first high lift retainer 412 and the low lift retainer 408 can cause the fiber coils 410 to be stored in an angular orientation within the housing 306. The coils of fibers 410 may have an upper coil part 422 and / or a lower coil part 424 resulting from the ratio of the low lift retainer 408 and / or the first and second high lift retainers 412 and 414.
The housing 306 can be configured so that the fiber coils 410 are retained in a manner in accordance with a minimum radius of curvature recommended by the manufacturer, which can be half the diameter
426. Assuming that a manufacturer specifies that 402A-D fibers should have a recommended radius of curvature of at least 1.5 inches. The fiber management part 308 of the housing 306 can be configured so that the fiber coils 410 are retained in an angular orientation using the low lift retainer 408 and one
or more first and / or second high lift retaining device 412 and / or 414. The angular orientation of the fiber coils 410 can facilitate achieving at least the minimum radius of curvature recommended by the manufacturer.
The fibers 402A-D can be terminated within the housing 306 using, by way of example, a similar number of receptacle bodies 416A-D. Receptacle bodies 416A-D may include any device capable of terminating an optical fiber and having signals pass through the available fiber to another device, such as a connector and / or a destination, such as a user's premises. Receptacle bodies 416A-D may include connectors to match finished fibers 402A-D with a receptacle body and / or fiber 402A-D may be matched with receptacle body 410A-D using a connection based on adhesives and / or mergers
The housing 306 may include a seal 418 located in a recessed area, or channel, to facilitate a seal with a base, such as the base 302. The seal 418 may include any device capable of facilitating a seal resistant to the moisture with a matching surface. By way of example, sealing gasket 418 may include an elastomeric material with or without adhesive, lubricant and / or sealing compounds such as liquids and / or gels.
Figure 5 illustrates a cross section of an exemplary embodiment of a fiber connection terminal housing 306 that employs a fiber management cavity for storing fiber coils in an angled orientation consistent with the principles of the invention. The housing 306 may include components illustrated and described with reference to Figures 3A, 3B and / or 4, such as the input channel 316, the output receptacle 310, the bundle of incoming fibers 318, etc. The housing 306 may employ a high lift retainer 412 to retain one or more fibers 402A-D. The first high lift retention device 412 can be used individually and / or in combination with other fiber retention devices. The first high lift retaining device 412 can be placed in the storage cavity 502 and can be slidably arranged in the mounting channel of the retaining device 344 for variable positioning of optical fibers 402A-D with respect to the inside of the housing 306.
As illustrated in Figure 5, the low lift retention device 408 can operate with one or more high lift retention devices 412 and / or 414 to retain the fiber coils 410 in an angled orientation 506 relative to the cavity of storage 502 and / or a face of the housing 508. The use of the angled orientation 506 can facilitate the storage of the fiber coils 410 without violating a radius of curvature recommended by the manufacturer. The embodiments may employ angular orientations having a wide range of angles with respect to the reference place, such as the face of the housing 508. In one embodiment, the angular orientation 506 with respect to the face of the housing 508 it may be in the order of magnitude of 20 ° to 60 ° and in another embodiment, it may be in the order of magnitude of 35 ° to 45 °. The storage of the fiber coils 410 in an angular orientation with respect to an outer surface of the fiber connection terminal 300, as opposed to a planar orientation with respect to an outer surface of the terminal 300, advantageously allows the overall dimensions to be reduced of the fiber connection terminal 300, while maintaining a minimum desired radius of curvature. The orientation of the angled fiber coil 410 can be reversed so that the base of the mounting channel of the retaining device 344 is associated with, by way of example, the base 302 rather than with a face of the housing 306. Housing 306 may include a dummy connector 504 to protect the output receptacle 310 when the output connector 312 is not installed.
Figure 6 illustrates an exemplary embodiment of a fiber retention device in accordance with an embodiment consistent with the principles of the invention. The fiber retention device of Figure 6 can be realized as a retention hook 600. The retention hook 600 may include a mounting post 602, a rear face 604, an upper face 606 and a retention face 608. The face rear 604, upper face 606 and retaining face 608 can form an inner channel 610 for the reception of one or more optical fibers. The retaining hook 600 may include any device capable of retaining one or more optical fibers in a desired position. The retaining hook 600 may be made of plastic, composite, metal, glass or similar material depending on the desired properties of the hook 600. By way of example, the fiber coils 410 may be placed within an inner channel 610. The coils of Fibers 410 may be retained using the inner surface of the retaining face 608. The tension existing in the fiber coils 410 may facilitate retention of the fiber coils 410 within the inner channel 610. The retaining hook 600 may include a support bracket. mounting 602. The mounting bracket 602 can be adapted to facilitate the adjustment of a height of the inner channel 610 with respect to the storage cavity 502 and / or other reference location. The mounting bracket 602 can be slidably disposed within the mounting channel of the retaining device 344 (Figure 3B and Figure 5) to adjust the height of the inner channel 610 with respect to a reference location.
The fiber management components, such as the retaining device mounting channel 344, the first central retaining device 404, the low lift retaining device 408 and the retaining hook 600 can be made of plastic, composite, metal material , rubber and the like. In one embodiment, the fiber management components are manufactured from the same material used to manufacture the terminal 300, so that the fiber management components can have the same thermal coefficients as, for example, the base 302 and the housing 306. By way of example, the base 302, the housing 306 and / or the fiber management components can be made of polypropylene.
Terminal 300 can be used in public utility pole mounting facilities where the bundle of incoming fibers 318 approaches terminal 300 through a break that originates from a strand located above terminal 300. In this configuration, terminal 300 may be adapted to receive a bundle of incoming fibers 318 from an input channel 316 located at an upper part of terminal 300. Alternatively, terminal 300 may have an input channel 316 located at a lower part of terminal 300. When the terminal 300 is adapted for entry from the bottom, an input cable may be required for bypass of the terminal on the post and form a loop on the post for entry at the bottom of the terminal. One or more outlet receptacles may be arranged to deter precipitation input as well as to channel water from receptacles 31A-
D. The 310A-D output receptacles can be mounted in order to facilitate access by a line operator having a desired approach angle regardless of whether it is an entry from the bottom or an entry from the top in the input channel 316 that is used.
As used herein, the approach angle may, in broad terms, refer to an intended direction and / or angle from which a line operator will approach and / or access terminal 300, a mounting bracket, an output receptacle 310 and / or an output connector 312 when connected to the output receptacle 310 and / or removed from the output receptacle 310. An approach angle may vary based on a mounting position of the terminal 300 (eg, on a post of public service, pedestal, building, etc.), the orientation of terminal 300 (eg, horizontal mounting vs. vertical mounting), an approach method used by a line operator (eg, scale approach, forklift and / or foot) and / or a work position taken by a line operator when interacting with terminal 300 (eg, using one hand while the other hand holds a ladder of scale and / or using two hands while on an ele wafer of wafer and / or while standing on the ground). In addition, the approach angle may take into account the size of a connector and / or cable that is coupled to an input receptacle and / or output receptacle 310, prevailing weather patterns, aesthetic appearance of terminal 300, the number of connections at terminal 300, etc.

In Figure 7A, terminal 700 may include a lower input channel 702 to receive a bundle of incoming fibers 318. The bundle of incoming fibers 318 can be sealed to the lower input channel 702 to form a weatherproof interface using, at by way of example, injection of filler adhesive, overmolding, sealant and / or weatherproof internals. The terminal 700 can facilitate the movement of water away from the lower inlet channel 702 by placing the inlet channel 702 in the vicinity of a lower part 703 of the terminal 700 when it is mounted, for example, on a utility pole. If the incoming fiber bundle 318 is received from a suspended strand, the incoming fiber bundle 318 can cause it to be installed next to terminal 700 and in an upward loop, while maintaining a certain radius of curvature, to pass the beam of incoming fibers 318 to the lower input channel 702.
Figure 7B illustrates an exemplary embodiment of a fiber connection terminal 704 that includes a fiber input channel located at an upper part 705 of terminal 704, consistent with the principles of the invention. In Figure 7B, terminal 704 may include an upper input channel 706 to receive a bundle of incoming fibers 318.

The input receptacle 802 may be plugged using an artificial input plug when the input connector is not present. 804. Terminal 800 may include the input receptacle 802 located at a bottom of the terminal 800. The input receptacle 802 can be adapted to facilitate protection against water penetration from a coincidence zone of the input receptacle 802 and the connector input 804 using, as an example, o-ring closures.
In Figure 8B, terminal 806 may include an input receptacle 802 to receive an input connector 804. The input receptacle 802 may be located at an upper part of terminal 806. The location of the input receptacle 802, in one part The upper end of terminal 806 may facilitate direct routing of a bundle of incoming fibers to the input receptacle 802 without requiring that the bundle of incoming fibers 318 be curved in, for example, a loop prior to the coincidence of the input connector 804 to the 802 input receptacle. The embodiments of Figures 8A and 8B may allow the installation of solid input connectors in a bundle of incoming fibers 318
at the time a fiber optic cable with multiple strands is manufactured. By way of example, if a bundle of incoming fibers 318 includes four optical fibers, the input connector 804 can be adapted to cause the optical signals to traverse the four available fibers in a similar number of optical fibers associated with the input receptacle 802. The input connector 804 may be plugged using a dummy receptacle to protect the optical fibers inside the connector when not in use. A dummy receptacle can provide a weather tight seal and can be removed when the input connector 804 is coupled to terminal 800 and / or 806. The embodiments of Figures 8A and 8B can facilitate the economical manufacturing of connection terminals of fibers while providing a way to keep sealed connectors and / or receptacles sealed until necessary. Although the embodiments associated with Figures 8A and 8B have illustrated the input receptacle 802 as it is located in a lower part or an upper part of the terminal 800 and 806, the input receptacle 802 may be located anywhere else. By way of example, the input receptacle 802 may be located on one side of terminal 800 and / or 806 and / or on a front surface and / or base of terminal 800 and / or terminal 806.
Figure 8C illustrates an area view of an exemplary embodiment of fiber connection terminals of Figures 8A and / or 8B showing the fiber retention and / or routing techniques that can be used within the terminal 800 and / or 806, respectively, consistent with the principles of the invention. The embodiment illustrated in Figure 8C may include a housing 801, a bundle of incoming fibers 318, a first and second central retention device 404, 406, a first and second high lift retention device 412 and / or 414, an input socket 802, an input connector 804, a rupture device 810, optical fibers 808A-D.

In one embodiment, the input receptacle 802 may receive signals associated with four optical fibers, the breaking device 810 can transmit the respective signals to the optical fibers 808A-D. The 808A-D optical fibers may have respective proximal ends and distant ends. The proximal ends of the optical fibers 808A-D can be coupled to the rupture device 810 and the distant ends can be associated with one or more output receptacles 310.

The fibers 808A-D optics can be cut longer than is necessary to reach from the rupture device 810 to one or more output receptacles, such as output receptacles 310A-D. The excess fiber associated with the optical fibers 808A-D may be placed in fiber reels using, by way of example, the low lift retainer 408 (not illustrated in Figure 8C) and / or first and second retention devices of high lift 412 and 414. The fiber coils can be arranged in accordance with the minimum radii of curvature specified by the manufacturer associated with the 808A-D optical fibers. The distant ends of the optical fibers 808A-D may have connectors attached for coupling to a similar number of receptacle bodies, such as the receptacle bodies 416A-D and / or the distant ends may be left bare and spliced / melted to the receptacle bodies

By way of example, the incoming fiber bundle 318, the output connector 312 and / or the output fiber 314 can impart loads and / or stresses on the terminal 300. In some situations, these charges and / or stresses can be transferred directly. to parts of terminal 300. The loads and / or stresses applied to terminal 300 may increase and / or decrease due to the warping of the cables, cables subject to wind loads and / or cables subject to ice loads. Constant and / or variable loads and / or stresses can result in stress cracking on parts of terminal 300. As an example, stress cracks can be formed at stress concentration points in terminal 300 , such as in the vicinity of the first transition zone 334, the second transition zone 338, the first inner angle 340 and / or the second inner angle 342. The embodiments may employ reinforcement techniques to mitigate the loads and / or efforts associated with the embodiments of fiber connection terminals, such as terminal 300.
Figures 9A and 9B illustrate an exemplary embodiment of a fiber connection terminal having a reinforced housing that may include reinforcing splints in locations that may be associated with areas of adverse stresses consistent with the principles. of the invention. The reinforced housing 900 (Figure 9A) may include an external splint 902 and / or an outer housing rib 904. The external splint 902 may include any
device capable of providing a retention force between two surfaces joined at an intersection and forming an angle. By way of example, the external splint 902 can save the valley zone 906 by contacting the first step face 908 and / or the first transition zone 910 and / or the second step face 912 and / or the second transition zone 914 (Figure 9A). The external splint 902 can operate to increase the stiffness of the first stepped face 908, the second stepped face 912 and / or the valley 906. The external splint 902 can be molded with the reinforced housing 900, held in place by adhesive and / or mechanical fixing device The external splint 902 can be made as a pair with a splint located in the vicinity of a first outer edge 918 of the reinforced housing 900 and the other splint located in the vicinity of a second outer edge 920 of the reinforced housing 900. The external splint 902 can be adapted so as not to interfere with the output receptacle 310 and / or output connector 312.
Embodiments of the reinforced housing 900 may use one or more internal splints in addition to, or instead of, the external splint 902. The internal splints may be located in the vicinity of the valley 906 within an interior cavity associated with the reinforced housing 900. Internal splints can operate to reinforce the valley 906 to reduce the detrimental effects of loads and / or stress applied to the reinforced housing. Embodiments may reinforce the valley 906 and / or parts of the housing in its vicinity by increasing the thickness of the material used to form the valley 906 and / or part of the housing in its vicinity. The cross section of the valley 906 can be increased in conjunction with the use of splints 902 or the cross section of the valley 906 can be increased instead of using splints
902. Embodiments may also employ support elements from an interior point of the valley 906, located within an interior cavity of terminal 900, to a base. The support elements may be configured and sized in order to exert a force on a part of a base when a terminal housing 900 is attached to the base. The loads associated with the valley 906 can be transferred through the support element to the base and / or to a mounting support associated with a base.
Embodiments of the reinforced shell 900 may include an outer shell rib 904 to increase the stiffness associated with one side of the reinforced shell 900. By way of example, one or more outer shell ribs 904 may be arranged practically perpendicular to a mounting face 916. An outer shell rib 904 can operate to increase the cross section of the reinforced shell 900 in the vicinity of a potentially adverse load and / or stress zone. The reinforced housing 900 may include internal housing ribs in addition to, or instead of, external housing ribs 904 and / or external splints 902.
Analytical tools such as the creation of finite element models can be used to analyze an existing enclosure design and / or to design new enclosures in order to minimize the probability of failures related to loads and / or efforts. By way of example, the creation of finite element models can be used to identify an embodiment of a staggered face enclosure, where the fixing devices and their corresponding joining structures are located in order to coincide with the locations of the high strain stress, such as, for example, at one or the other end of a valley 906. In particular, the fixing devices can be used to attach the enclosure to a base in a manner that provides reinforcement to the valley 906.

The dummy connector 1408 can be removed when an output connector coincides with the output receptacles 1410A-H.
The first end surface 1420, the second end surface 1422, the first rear surface 1416 and the second rear surface 1418 can operate in conjunction with the first face 1412 and the second face 1414 to form an airtight enclosure.

Embodiments of the terminal 1400 can be attached to the mounting brackets adapted and / or attached to utility posts, suspended strands, walls, fiber distribution concentrators and similar elements. Embodiments of the terminal 1400 may also use receptacle orientations, arrangements of the same level, coincidence angles, global lengths and / or global widths that vary depending on the particular installation locations, installation orientations and / or angles of expected approach.
Figure 15 illustrates an exemplary embodiment of a fiber connection terminal 1500 having outlet receptacles and contoured surfaces associated with the areas of the receptacle cavities, in a manner consistent with the principles of the invention. Terminal 1500 may include a housing 1506, a contoured surface 1508, a flange 1510, an outlet receptacle opening 1512, a receptacle mounting surface 1514, an input receptacle opening 1516, an integrated hole 1518, an appendix of housing lever 1520 and a fiber storage part 1522.
Terminal 1500 may include any device capable of receiving an incoming optical fiber and making a signal present there available for an output receptacle. The terminal 1400 may be manufactured in a manner compatible with the terminals as described with reference to Figures 3A, 13 and 14A-C. Terminal 1500 may include a housing 1506 and a base that can be manufactured using, by way of example, injection molding techniques known in this sector. The housing 1506 may form an internal cavity that may include a fiber storage part 1522. The fiber storage part 1522 may admit the excess fiber in reels held in a practically flat orientation and / or maintained in an angular orientation, such as The angular orientation described with reference to Figure 5. The housing 1506 may include one or more outlet receptacles that may be associated with a contoured surface 1508 and / or a receptacle mounting surface 1514.
The contoured surface 1508 can be located in the vicinity of the outlet receptacle opening 1512. The contoured surface 1508 can be configured, sized and arranged to facilitate protection against water contacts with the outer surface of the housing 1506. The contoured surface 1508 it can operate to prevent the accumulation of ice around the interface of an outlet receptacle in the receptacle opening 1512 and / or an outlet connector, such as the outlet connector 312. The contoured surface 1508 can be designed for contact protection with water for a particular mounting orientation, such as in a utility pole, or it can be designed to facilitate protection against water for a plurality of mounting orientations, such as for horizontal mounting on a strand and for vertical mounting in a public service post. When pairs of outlet receptacles are used, as illustrated in Figure 15, a flange 1510 can be used between two contoured surfaces 1508 to facilitate the removal of water around the outlet receptacle opening 1512.
Embodiments of the invention, using contoured surface 1508, may include features associated with other embodiments of the connection terminals. By way of example, the terminal 1500 may include a lever appendix 1520, one or more integrated holes 1518 that can be used to secure the housing 1506 to a base during service, an inlet receptacle opening 1516, a surface of receptacle assembly 1514, an angled coil storage location inside the housing 1506, etc. Ways to
embodiment of the terminal 1500 can use the input receptacle opening 1516 in the vicinity of a lower part of the housing 1506 and / or in the vicinity of a lower part of the housing 1506 to receive a bundle of incoming fibers.
Figure 16 illustrates an exemplary embodiment of a fiber connection terminal 1600 that employs a cylindrical enclosure, consistent with the principles of the invention. The cylindrical terminal 1600 may include, among other things, an input end cap 1602 having an input receptacle 1604, a first output section 1606 having a first plurality of output receptacles 1608A, 1608B, a second output section 1610 which has a second plurality of outlet receptacles 1608C, 1608D, 1608E and an end storage cap 1614. The cylindrical terminal 1600 may offer structural rigidity in a sufficient space package due to the cylindrical shape of the terminal. The cylindrical shape of terminal 1600 can facilitate passage through the pulleys used to deploy strands on utility posts and / or below ground. The cylindrical terminal 1600 may include sections that can be adapted, when necessary, to obtain a terminal having a desired number of receptacles 1608.
The input end cap 1602 can be molded from plastic material and can include an input receptacle 1604 to receive an input connector containing multiple optical fibers. In one embodiment, the input receptacle 1604 can use several fibers that match the number of output receptacles. The inlet end cap 1602 may include an outer surface and an inner surface with the inner surface forming an inlet cavity. The input end cap 1602 may include an adaptation surface of the input end cap 1616 for the coincidence of the input end cap 1602 with the first outlet section 1606. The fibers can be installed from the input receptacle 1604 through the cavity of the input end cap 1602 en route to the first output section 1606. The fibers associated with the input receptacle 1604 can be protected from the elements when the terminal 1600 is mounted. The input end cap 1602 can include a channel of input instead of an input receptacle 1604.
The first outlet section 1606 may be molded from plastic material and may include one or more receptacle cavities 1620 arranged around an outer surface of the outlet section 1606. The receptacle cavity 1620 may include a receptacle support surface having an opening to receive the 1608A and / or 1608B output receptacles. The receptacle cavity 1620 may be separated by a given spacing that can be measured as a distance and / or as a number of angular degrees. As an example, if two output receptacles are used in an output section, the receptacles can be separated at an angle of 180 ° with respect to a center line of terminal 1600. If four output receptacles are used, the output receptacles They can be separated at an angle of 90º.
The first outlet section 1606 may include a first matching surface 1622A and a second matching surface 1622B. The first coincidence surface 1622A can be configured and sized to coincide with the coincidence surface of the inlet end cap 1616. A seal can be obtained when the inlet end cap 1602 and the first outlet section 1606 are matched together. The first output section 1606 can be modeled so that it has an internal volume to accommodate optical fibers received from the input end cap 1602 and to accommodate fibers that pass through the first output section 1606 en route to the second section. output 1610. The first output section 1606 may include one or more output receptacles 1608A, 1608B arranged in receptacle cavities 1620. The first and second matching surfaces 1622A, 1622B can be practically symmetrical and can be configured and sized to form joints sealing with adjacent sections.
The second outlet section 1610 may include a third matching surface 1624A and a fourth matching surface 1624B. The second output section 1610 may be practically similar to the first output section 1606 in form and / or function. In one embodiment, the second output section 1610 may include the same number of output receptacles that are present in the first output section 1606. When the first and second output sections 1606, 1610 are coincident together, the receptacles of Output in one section may be offset from the output receptacles in a nearby section in an angular displacement 1626. The angular displacement 1626 can be selected to facilitate access to virtually all output receptacles associated with the terminal 1600. It is assumed that each outlet section 1606, 1610 contains four output receptacles 1608 that have relative spacings of an approximate angle of 90 ° to each other. When the terminal 1600 is mounted, the first output section 1606 can be offset by an approximate angle of 45 ° with respect to the second output section 1610, so that the receptacle 1608D is practically aligned between the output receptacles 1608A and 1608B. Terminal 1600 can include virtually any number of output receptacles and can be made by coupling additional output sections together.
The extreme storage cap 1614 may include an outer surface and an inner surface with the inner surface defining an inner cavity that can be used to store excess optical fiber. The end storage cap 1614 may use fiber guides, retention hooks, adhesive, etc., to retain excess fiber in a desired orientation. In addition, the storage end cap 1614 can retain the coils in one or more angular orientations to facilitate obtaining a certain radius of curvature. As an example, the excess fiber associated with the 1608A-D output receptacles can be wound into coils and
stored in an angular orientation to maintain at least the minimum radii of curvature recommended by the manufacturer for the fibers in the coils. The storage end cap 1614 may include a storage cap matching surface 1628 that can be configured and sized in order to form a tight seal when coupled to the fourth matching surface 1624B, of the second outlet section 1610.
One or more sections of the cylindrical terminal 1600 may use o-rings or other sealing devices, which meet the established standards, to facilitate the formation of gaskets at the intersections of the inlet end cap 1602, the first outlet section 1606, the second outlet section 1610 and / or the storage end cap 1614. In one embodiment, a cylindrical fiber connection terminal, such as terminal 1600, can have an outside diameter of the order of magnitude of 3.5 inches (89 mm ).
Figure 17A illustrates an embodiment of a fiber connection terminal 1700 that employs loopback pins in a manner consistent with the principles of the invention. The fiber connection terminal 1700 may be configured in a manner similar to the fiber connection terminals described with reference to Figures 3A, 4, 5, 13, 14A, 15 and / or 16. Terminal 1700 may include output receptacles 1710A-D, a first loopback assembly 1701 and second loopback assembly 1703. Each loopback assembly 1701, 1703 may include a first output connector 1702 and a second output connector 1704 coupled, communicatively , through an output fiber 1706 having a return loop portion 1708.
The output receptacles 1710A-D can be associated in pairs by means of the first loop return assembly 1701 and the second loop return assembly 1703 for testing. As an example, the output receptacles 1710A and 1710D may form a pair through the first loop return assembly 1701. The output connectors 1702 and 1704 can be configured to couple the output receptacle 1710A to 1710D, so that a Optical signal present in receptacle 1710A can be transmitted to output receptacle 1710D.
Embodiments, which employ return loop connectors, can facilitate testing of two incoming optical fibers (e.g., 1710B and 1710C) without requiring that a line operator be present at the fiber connection terminal during the tests. As an example, a test device and / or a technician in a central office and / or a fiber distribution hub can send a test signal along a first incoming optical fiber associated with the output receptacle 1710B. The test signal may pass from the output receptacle 1710B through the first output connector 1702 and the loopback fiber 1706 to the second output connector 1704 and the output receptacle 1710C. The test signal can be moved through a second incoming optical fiber to the central office and / or fiber distribution hub where the technician is located. The technician can detect the presence and / or absence of the test signal in the second incoming optical fiber.
If a fiber connection terminal includes eight output receptacles, four sets of loopback connectors can be used to allow testing of each output and / or fiber receptacle associated with the fiber connection terminal. When a customer is connected to the fiber connection terminal, the loopback assembly can move from the output receptacle that will be connected to the customer and / or be removed from the opposite output receptacle. A dummy connector can be inserted into the opposite outlet receptacle to prevent penetration of dirt and moisture into the opposite receptacle, as long as it is not connected to a customer. An output connector associated with an output cable installed to the customer's premises can be connected to the output receptacle used to serve the customer.
Prior test techniques may require a line operator to inject a signal into an optical fiber at a central office and / or fiber distribution hub and then initiate the test for a fiber connection terminal. The line operator may leave a diesel truck at rest while climbing on a pole and determine if the test signal is present in an output receptacle. After determining whether the signal is present, the line operator may return to the central office and / or fiber distribution hub and connect the test signal to another fiber associated with, for example, an adjacent output receptacle in The fiber connection terminal. The line operator can return to the fiber connection terminal and determine if the test signal is present in the adjacent output receptacle.
Embodiments of the invention that make use of loop return connector assemblies 1701 and 1703 can provide significant cost savings when used to test fiber connection terminals. Cost savings can result from the time saved by eliminating displacement between a place in the fiber connection terminal and a central office and / or fiber distribution hub, while testing a fiber connection terminal. Cost savings can also result from the fuel saved by eliminating trips to and from a fiber connection terminal when testing. The elimination of trips to and from a fiber connection terminal can also conserve natural resources by reducing fossil fuel consumption.
Figure 17B illustrates an example flow chart of a method for testing a fiber connection terminal used in a communication network consistent with the principles of the invention. A fiber connection terminal can be installed in a multi-fiber strand together with loopback assemblies 1701 and / or 1703 (act. 1720). As an example, a fiber connection terminal can be installed in a multi-fiber strand in a mounting installation. As an example, the fiber connection terminals can be attached to breakage elements, or ties,
in association with the multifiber bull. Finished breaks, or ties, can be attached to the multifiber strand for transport to an installation site. An initial check of the continuity of the signal, in the optical fibers leading to the fiber connection terminal, can be carried out in the assembly installation prior to the issuance of the multifiber fiber / fiber connection terminal system. A multi-fiber strand can have numerous terminals and built-in fiber connections.
The multifiber strand and the fiber connection terminal are installed in a predetermined place (act.1730). By way of example, the multifiber strand can be suspended from two or more utility posts and fiber connection terminals can be attached to said utility posts. A near end of the multifiber strand can be associated with a central office and / or an FDH that serves, as an example, a residential development. A distant end of the multifiber strand can be located several kilometers away from the central office and / or FDH and can be associated with a fiber connection terminal. A deployed fiber connection terminal may have an optical fiber associated with each output receptacle. The fiber connection terminal can receive an incoming signal in an optical fiber and provide the signal to a customer when the service is connected to the customer.
A signal generator can be connected to a fiber associated with a first output receptacle (act.1740). By way of example, a signal generator can be located, by way of example, a central office. The signal generator can be connected to a first fiber that serves a first output receptacle in a fiber connection terminal. A first input connector, associated with a loopback assembly, can be coupled to the first output receptacle. A corresponding output connector, associated with the loopback assembly, can be inserted into a second output receptacle associated with a second fiber that returns, by way of example, to the central office. Signal detector can be connected to a second fiber in the central office (act.1750).
Since the first output connector 1702 is communicatively coupled to the second output connector 1704 through a loopback part 1708, a signal arriving at the first output receptacle can pass through the first output connector 1702, the loop return part 1708 and the second output connector 1704 to be present in the second output receptacle. An optical signal present in the second output receptacle can pass through the second optical fiber back to the central office and / or FDH. The optical signal that crosses the second optical fiber can be detected using the signal detector (act.1760). The presence of an optical signal in the second fiber may indicate that the first fiber and the second fiber are operating properly. In contrast, if no signal and / or any degraded signal is detected in the second fiber, the first fiber and / or the second fiber may not be functioning properly. When the tests are completed, a loop return assembly 1701 can remain in place until a customer is connected to the fiber connection terminal. At that time, a loop return assembly 1701 can be removed and reused in another fiber connection terminal. A dummy connector can be inserted into an unused outlet receptacle to prevent contamination by dirt and / or moisture.
The method depicted in Figure 17B may allow a single technician to test some and / or all of the fiber connection terminals associated with one or more multifibre strands from an electronic location. Testing from a single location can provide significant time and fuel savings compared to tests of fiber connection terminals that have a technician move from a central office and / or FDH to and from a fiber connection terminal installed in field. The method of Figure 17B may also allow testing during adverse weather conditions, since the technician may be located indoors, such as when testing from a central office.
Figure 18 illustrates a flow chart showing an exemplary method for routing fiber strands into a fiber connection terminal using an angled fiber management system, consistent with the principles of the invention. . The method begins with the reception of a housing (act. 1810). By way of example, a housing can be used as in the embodiment illustrated with reference to Figures 3A, 9A, 11B, 13, 14A, 15 and / or 16. An outlet receptacle can be installed in a housing using known techniques in the relevant techniques (act. 1820). An input cable, which has one or more optical fibers, can be passed through an input channel, such as the input channel 260, associated with a housing of the fiber connection terminal (act. 1830). Alternatively, an input cable can be terminated with an input connector and attached to an input receptacle in the housing instead of the input channel. The optical fibers associated with the input cable can be installed inside the housing and used, by way of example, centrally managed retention devices (act. 1840). In one embodiment, a central management retention device may be located between two output receptacles, practically along the center line of the housing. One or more ends, such as distant ends, of the optical fibers may be connected to one or more output receptacles (step 1850). The optical fibers can be fused to an output receptacle and / or can be terminated with a connector configured and arranged to match a connector / receptacle associated with an output receptacle mounted in the housing.
An excess fiber optic can be formed in one or more coils and maintained as an angled management coil inside the housing 1306 using a combination of low lift retention devices and / or high lift retention devices (step 1860). The angled management coil may be configured in order to maintain a radius of curvature recommended by the manufacturer of, for example, 1.2 inches and / or 1.5 inches.
Figure 19 illustrates a flow chart showing an example method of installing a fiber connection terminal using a support, consistent with the principles of the invention. A mounting location for the fiber connection terminal is selected (act. 1910). Mounting positions may include utility posts, suspended strands, equipment racks, headquarters and / or building structures. A mounting bracket can be attached to the mounting surface at a desired mounting location (act. 1920). The mounting bracket can be attached using nails, screws, rivets, adhesive, etc. A fiber connection terminal, which includes a housing and / or base, can be placed on or against the mounting bracket (act. 1930). The housing and / or base can be fixed to the support using retaining devices, braces, bolts, keyed interlocking devices and / or a friction-based element that is suitable (act. 1940). By way of example, the housing and / or the base can be joined using screws, wire braces, nylon braces or using a keyed friction retention mechanism, such as a groove and support arrangement. A dummy output connector can be removed from an output receptacle (act. 1950). An output connector having an associated output fiber can be connected to the output receptacle to transmit electromagnetic data, such as optical data, to a customer through an output fiber (act. 1960).
Figure 20 illustrates a flowchart showing a method, by way of example, for installing fiber connection terminals and / or output connectors on a multi-fiber strand prior to field deployment, consistent with the principles of the invention. By way of example, the method of Figure 20 can be performed, to a large extent, in a manufacturing and / or assembly facility. The method can be initiated by receiving information about a desired location of a fiber connection terminal (act. 2010). This location information can be used to identify, or determine, a place of rupture in the multifiber strand. A fiber connection terminal can be installed at the breaking point, such as joining the fiber connection terminal to a fiber bundle extracted from the multifiber strand (act. 2020). As an example, it can be determined that an eight-output fiber connection terminal is required in a utility post that has a specific set of associated geographic coordinates. In the right place within the multifiber strand, a break can be created with the inclusion of eight fibers. This break can provide eight input fibers for the fiber connection terminal.
Referring again to Figure 20, a determination can be made as to whether or not an output connector must be attached to the rupture fibers and / or if a fiber connection terminal must be incorporated there (act. 2030). If an input connector must be incorporated, the input connector can be attached to a bundle of incoming fibers (act. 2040). In contrast, if a fiber connection terminal must be incorporated, said fiber connection terminal can be attached to the appropriate number of rupture strands (act. 2050).
After act. 2040 and / or act. 2050, the fiber connection terminal and / or the input connector can be fixed to the incoming fiber bundle in a manner that facilitates efficient field deployment (act. 2060). As an example, an input connector and the associated incoming fiber bundle can be attached to the multifiber strand using insulating tapes. The bundle of incoming fibers and the input connector can be wrapped with the multifiber strand in a way that facilitates the passage of the assembly through the standard pulleys, which can be used to install the multifibre strands in the utility poles and / or below ground level. The multifibre strand can be deployed in the field to provide data communication services to subscribers (act. 2070).
Although the preferred preferred embodiments have been the object of illustration in this description, alternative configurations of fiber connection terminals consistent with aspects of the invention are also possible. By way of example, an alternative embodiment may include a fiber connection terminal having threaded insertion elements and / or feed grooves for the adaptation of particular sizes and designs of suspended strands. In particular, the insertion elements and grooves can be configured to fit with selected types of mounting brackets for use with different sizes and types of strands. In addition, the support assembly / insertion element / enclosure can be designed to provide receptacles in an orientation optimized for intended approach angles, which can be used by a line operator when accessing the installed enclosure. In addition, the support can be designed in order to eliminate displacement requirements, rotation around the strand and / or warping while being accessed by a line operator
Embodiments of the invention can be mounted on metal strands of strands that are suspended between utility posts. In these applications, embodiments of fiber connection terminals can be securely attached to the strand to prevent longitudinal displacement of the fiber connection terminal along the strand. In addition, the fiber connection terminal can be fixed to prevent rotational displacement around the strand. Finally, the fiber connection terminal and / or mounting device can be configured so that the fiber connection terminal is suspended at a fixed distance below the strand and / or so that the fiber connection terminal is not warped and / or pendant.
Another embodiment of a fiber connection terminal may include output connectors installed in a housing associated with a fiber connection terminal. The output connectors can be used instead of, or in addition to, output receptacles.
Other embodiments of a fiber connection terminal may include provisions such as connectors, receptacles, connection hoses, etc., for transmitting communication signals through copper wires in addition to
transmit optical signals through the output fibers. As an example, the output receptacles may include an optical fiber and one or more copper conductors. The output connectors in coincidence with the receptacles can transmit optical signals and electrical signals to a destination.
Another embodiment of the fiber connection terminals may include electronic data storage and communication devices to facilitate network deployment and configuration. By way of example, an embodiment of a fiber connection terminal may be provided with a radio frequency identification tag (RFID). The RFID tag may store information related to the subscribers associated with the outbound receptacles on the premises, the central offices (COs) that provide data to the premises, the information associated with the maintenance of the premises and / or the geographical location of the premises. The information stored in the RFID tag can be consulted by a line operator on the ground or in a vehicle, before boarding a utility pole using a conventional RFID tag reader. In addition, new information can be stored in the RFID tag to accurately reflect the operating status and configuration of the enclosure. Fiber connection terminals, provided with RFID tags or other electronic processing communication and / or storage devices may, by way of example, be referred to as intelligent fiber connection terminals. The fiber connection terminals can also be configured with radio frequency and / or ground line communication capabilities. By way of example, a fiber connection terminal may be provided with a cellular transceiver that can be configured to facilitate testing of the input and / or output receptacles associated with the fiber connection terminal and / or to facilitate the error detection, such as water penetration inside an enclosure.
In other alternative embodiments, the fiber connection terminals may be provided with means to receive removable rain protections to prevent precipitation from coming into contact with the connectors and receptacles when the fiber connection terminals are subject to service. When a service or operational update operation is completed, a line operator can remove the rain protection. The rain protection can be configured to be reusable, so that it can be used when servicing other fiber connection terminals.
In other alternative embodiments, a base can have a receiving surface that is a channel that presents essentially any shape that can be used with or without a gasket to facilitate a gasket with a housing. Alternatively, the fiber connection terminal housing may include an adaptation channel configured and sized to form a seal with a channel in the base and / or the housing may contain a channel with, or without, a gasket while that the base element includes a practically flat coincidence surface. In addition, the base element can be configured to have an input connector or receptacle and / or an output connector or receptacle to facilitate the output and / or input of electromagnetic signals.
In another alternative embodiment, a cylindrical fiber connection terminal may include an end entry cap for a first exit section and / or a molded storage end cap for a second exit section. The first outlet section may be configured and sized to fit a surface of the second outlet section to form a virtually airtight enclosure. Additional output sections can be added between the first output section and the second output section to achieve virtually any number and / or configuration of output receptacles.
