Patent Description:
This applications also claims the benefit of priority under <NUM> USC §<NUM> of <CIT>; <CIT>; <CIT>; <CIT>; and <CIT>; all designating the United States of America.

The disclosure is directed to fiber optic devices providing at least one optical connection port along with methods for making the same. More specifically, the disclosure is directed to fiber optic extender ports comprising one or more connection ports and a securing feature associated with the connection port for securing an optical connector along with methods of making the same.

Optical fiber is increasingly being used for a variety of applications, including but not limited to broadband voice, video, and data transmission. As bandwidth demands increase optical fiber is migrating deeper into communication networks such as in fiber to the premises applications such as FTTx, <NUM> and the like. As optical fiber extended deeper into communication networks the need for making robust optical connections in outdoor applications in a quick and easy manner was apparent. To address this need for
making quick, reliable, and robust optical connections in communication networks hardened fiber optic connectors such as the OptiTap® plug connector were developed.

Multiports were also developed for making an optical connection with hardened connectors. Prior art multiports have a plurality of receptacles mounted through a wall of the housing for protecting an indoor connector inside the housing that makes an optical connection to the external hardened connector of the branch or drop cable.

The different branch or drop cables may require different lengths to reach the desired connection location. With factory-terminated solutions there are typically several lengths of drop cables that are offered and the user can use the length of connectorized drop cable that best fits the link length required. However, this can require the craft to stock several different length drop cables and lots of slack storage of cable if the lengths are not well-matched to the link length required.

Consequently, there exists an unresolved need for devices that allow flexibility for the network operators to quickly and easily make optical connections to extend the reach of an optical network while also addressing concerns related to limited space, organization, or aesthetics.

<CIT> discloses an adapter with a push-push coupling mechanism having flipper that cooperates with a dual pin on the connector. The push-push mechanism comprises triple prong spring clip, flipper and nest which serves as the vertical axis that the flipper pivots. flipper cooperates with dual pin disposed on connector during insertion and withdrawal for actuating the push-push mechanism.

<CIT> discloses a hybrid connector <NUM> for use with hybrid adapter <NUM>. The hybrid adapter requires an adapter housing defined by an outer part and inner part.

<CIT> and <CIT> disclose other prior art.

The disclosure is directed to extender ports comprising at least one connection port and a securing feature associated with the connection port. Methods of making the devices are also disclosed. The devices can have any suitable construction such as disclosed herein such a connection port that is keyed for inhibiting a non-compliant connector from being inserted and potentially causing damage to the device.

The invention provides an extender port according to claim <NUM>, as well as a method of making an extender port according to claim <NUM>.

It is to be understood that both the foregoing general description and the following detailed description present embodiments that are intended to provide an overview or framework for understanding the nature and character of the claims. The accompanying drawings are included to provide a further understanding of the disclosure, and are incorporated into and constitute a part of this specification. The drawings illustrate various embodiments and together with the description serve to explain the principles and operation.

Reference will now be made in detail to the embodiments of the disclosure, examples of which are illustrated in the accompanying drawings.

The concepts for the devices disclosed herein are suitable for providing at least one optical connection for indoor, outdoor or other environments as desired. Generally speaking, the devices disclosed and explained in the exemplary embodiments are extender ports, but the concepts disclosed may be used with any suitable device as appropriate. As used herein, the term "extender port" means any device comprising a first connection port for receiving a fiber optic connector and making an optical connection. In one embodiment, the extender port has a first connection port and a second connection port that are aligned for making an optical connection between two external fiber optic connectors. Thus, the extender port may be used to customize or extend the length of an optical link by using two cables connected by the extender port,
thereby providing further flexibility to the network provider. In other embodiments, the extender port can be fixed to a tether cable for optical connection with an external connector. The connection port also has a securing feature associated with the at least one connection port for securing and releasing the fiber optic connector. By way of example, the extender port may further include other components such as active components such as a wireless sub-assembly device having electronics for transmitting or receiving a signal disposed within the shell of the extender port.

The concepts disclosed advantageously allow compact form-factors for the extender ports and may also optionally include at least one connection port comprising a keying portion for aligning the fiber optic connector with the securing feature associated with the connection port. Although, extender ports are shown and described for a single inline connection, the concepts are scalable to many in-line connection ports on a single device in a variety of arrangements or constructions. The securing features disclosed herein for devices engage directly with a portion of connector without conventional structures like prior art devices that require the turning of a coupling nut, bayonet or the like. As used herein, "securing feature" excludes threads and features that cooperate with bayonets on a connector. Thus, the devices disclosed may allow connection port to be closely spaced and may result in small devices since the room and structure needed for turning a threaded coupling nut or bayonet is not necessary. The compact form-factors may allow the placement of the devices in tight spaces in indoor, outdoor, buried, aerial, industrial or other applications while advantageously providing a device having at least one connection port with a robust and reliable optical connection in a removable and replaceable manner. The disclosed devices may also be aesthetically pleasing. Organizers may also be used with the extender ports for providing organization for an array of extender ports having optical connections.

The devices disclosed are simple and elegant in their designs. The devices disclosed comprise at least one connection port and a securing feature associated with the connection port that is suitable for retaining an external fiber optic connector received by the connection port. A keying portion of the connection port may cooperates with a key on a complimentary external fiber optic connector to inhibit damage to the connection port by inhibiting the insertion of a non-compliant connector while also ensuring the correct rotational alignment to secure the fiber optic connector. The keying portion may also aid the user during blind insertion of the connector into the connection port of the device to determine the correct rotational orientation with respect to the connection port when a line of sight is not possible or practical for alignment. The keying portion may be an additive keying portion to the primitive geometric round shape of the connection port passageway <NUM> such as a male key. However, the concepts for the connection ports <NUM> of devices may be modified for different connector designs without a keying portion as well.

The concepts disclosed advantageously allow the quick and easy connection and retention by inserting the fiber optic connectors directly into the connection port of the device without the need or space considerations for turning a threaded coupling nut or bayonet for retaining the external fiber optic connector. Generally speaking, the securing features disclosed for use with extender ports herein may comprise one or more components with at least one component translating for releasing or securing the external fiber optic connector to the device. Specifically, the securing feature is capable of translating within the shell. As used herein, the term "securing feature" excludes threaded portions or features for securing a bayonet disposed on a connector.

Since the connector footprint used with the devices disclosed does not require the bulkiness of a coupling nut or bayonet, the fiber optic connectors used with the devices disclosed herein may also be significantly smaller than conventional fiber optic connectors.

The devices disclosed comprise a securing feature for directly engaging with a suitable portion of a connector housing of the external fiber optic connector or the like for securing an optical connection with the device. Different variations of the concepts are discussed in further detail below. The structure for securing the fiber optic connectors in the devices disclosed allows much smaller footprints for both the devices and the fiber optic connectors along with a quick-connect feature. Although shown as simplex devices, the device may also have a dense spacing of connection ports within a shell such as a duplex designs or beyond if desired. The concepts disclosed advantageously allow a scalable and relatively dense and organized array of connection ports in a relatively small form-factor while still being rugged for demanding environments.

The concepts disclosed herein are suitable for optical distribution networks such as for Fiber-to-the-Home or <NUM> applications, but are equally applicable to other optical applications as well including indoor, automotive, industrial, wireless, or other suitable applications. Additionally, the concepts disclosed may be used with any suitable fiber optic connector footprint that cooperates with the securing feature of the device. Various designs, constructions, or features for devices are disclosed in more detail as discussed herein and may be modified or varied as desired.

<FIG> is an exploded view of explanatory extender port <NUM> comprising at least one connection port <NUM> for making optical connections. Generally speaking, extender port <NUM> comprises at least one connection port <NUM> being a portion of a shell <NUM> of the device. By way of explanation, at least one connection ports <NUM> is molded as a portion of shell <NUM>.

Generally speaking, extender port <NUM> comprises a shell <NUM> comprising a body <NUM> and one or more connection ports <NUM> disposed on a first end or portion <NUM> of extender port <NUM>. The connection ports <NUM> are configured for receiving and retaining external fiber optic connectors <NUM> such as shown in <FIG> for making one or more optical connections within the extender port <NUM>. In the embodiment of <FIG>, fiber optic connectors <NUM> are received from each end of the extender port <NUM> for making an optical connection between the fiber optic connectors <NUM> within the device. Although, single-fiber connectors <NUM> are shown, the concepts may be used with multi-fiber connectors as well.

Extender port <NUM> of <FIG> comprises a first connection port <NUM> and a second connection port <NUM>' that are inline or aligned for making an optical connection between fiber optic connectors <NUM> that are inserted from respective ends of the extender port <NUM>. In other embodiments, the extender port may have a fixed cable <NUM> on one end and a single connector port <NUM> for making an optical connection with optical fibers of the fixed cable such as shown in <FIG>.

Connection ports <NUM> each comprise a respective optical connector opening <NUM> extending from an outer surface <NUM> of the extender port <NUM> into a cavity <NUM> of the extender port <NUM> and defining a connection port passageway <NUM>. At least one securing feature <NUM> is associated with the connection port passageway <NUM> for cooperating with the external fiber optic connector <NUM>. The securing feature may translate for releasing or securing the external fiber optic connector <NUM>. One or more respective securing feature passageways <NUM> such as shown in <FIG> extend from the outer surface <NUM> of extender port <NUM> and cooperate with the respective connection port passageways <NUM> of the extender port <NUM>. Respective securing features <NUM> are associated with the connection port passageways <NUM> and may have a portion of the securing feature <NUM> disposed within a portion of the securing feature passageway <NUM> of the extender port <NUM>.

Optical connections to the extender ports <NUM> are made by inserting one or more suitable external fiber optic connectors <NUM> into respective connection port passageways <NUM> as desired. Specifically, the connection port passageway <NUM> is configured for receiving a suitable external fiber optic connector <NUM> (hereinafter connector) of a fiber optic cable assembly <NUM> (hereinafter cable assembly). Each connection port passageway <NUM> is associated with a securing feature <NUM> for retaining (e.g., securing) connector <NUM> in the extender port <NUM>. The securing feature <NUM> advantageously allows the user to make a quick and easy optical connection at the connection port <NUM> of extender ports <NUM> by pushing the connector <NUM> into the port until it is secured. The securing feature <NUM> may operate for providing a connector release feature when actuated such as by pushing downward.

Specifically, the connector <NUM> may be retained within the respective connection port <NUM> of the device by pushing and fully-seating the connector <NUM> within the connection port <NUM> as shown in <FIG>. To release the connector <NUM> from the respective connection port <NUM>, the securing feature <NUM> is actuated by pushing downward to translate the securing feature <NUM> a suitable distance, thereby releasing the securing feature from the connector housing and allowing the connector to be removed from the connection port <NUM>. Stated another way, the at least one securing feature <NUM> is capable of releasing the connector <NUM> when translating within a portion of a securing feature passageway <NUM>. The full insertion and automatic retention of the connector <NUM> may advantageously allow one-handed installation of the connector <NUM> by merely pushing the connector into the connection port <NUM>. The extender ports <NUM> disclosed accomplish this connector retention feature upon full-insertion by biasing the securing feature to a retain position. However, other modes of operation for retaining and releasing the connector <NUM> are possible according to the concepts disclosed. For instance, the securing feature <NUM> may be designed to require actuation for inserting the connector <NUM>; however, this may require a two-handed operation.

Securing feature <NUM> may be designed for holding a minimum pull-out force for connector <NUM>. In some embodiments, the pull-out force may be selected to release the connector <NUM> before damage is done to the device or the connector <NUM>. By way of example, the securing feature <NUM> associated with the connection port <NUM> may require a pull-out force of about <NUM> pounds (about 220N) before the connector <NUM> would release. Likewise, the securing feature <NUM> may provide a side pull-out force for connector <NUM> for inhibiting damage as well. By way of example, the securing feature <NUM> associated with the connection port <NUM> may provide a side pull-out force of about <NUM> pounds (about 110N) before the connector <NUM> would release. Of course, other pull-out forces such as <NUM> pounds (about 330N) or <NUM> (about 440N) pounds are possible along with other side pull-out forces.

The securing features <NUM> disclosed herein may take many different constructions or configurations. By way of explanation, securing features <NUM> may be formed from a single component as shown in <FIG> or a plurality of components as shown in <FIG>. Furthermore, the securing features <NUM> or portions of securing features <NUM> may be constructed as sub-assemblies such as shown in <FIG> for easy assembly. Still other variations are possible. <FIG> depicts a single securing feature <NUM> having opposing locking features that cooperates with mating connection ports <NUM>.

Generally speaking, the extender ports <NUM> comprise at least one connection port <NUM> defined by an optical connector opening <NUM> extending into a cavity <NUM> of the extender port <NUM> along with a securing feature <NUM> associated with the connection port <NUM>.

More specifically, <FIG> is an exploded view of extender port <NUM> comprising at least one connection port <NUM> disposed on the extender port <NUM> with the connection port <NUM> defined by an optical connector opening <NUM> extending from an outer surface <NUM> of the extender port <NUM> into a cavity <NUM> of the extender port <NUM> and defining a connection port passageway <NUM>. Extender port also comprises at least one securing feature passageway <NUM> for receiving at least a portion of the securing feature <NUM>. Securing features <NUM> are biased to a retain position using respective resilient members 310R. The securing feature passageways <NUM> extend from the outer surface <NUM> of extender port <NUM>. This extender port <NUM> comprises a shell <NUM> having a first portion 210A and a second portion 210B along with an adapter assembly 230A.

<FIG> depicts connectors <NUM> aligned at opposite ends of the extender port <NUM> for insertion into respective connection ports <NUM> and <FIG> depicts a plurality of connectors <NUM> retained within respective connection ports <NUM> of the assembled extender port <NUM>. As shown in <FIG>, extender ports <NUM> may have a fixed tether cable <NUM> attached at one end and a mating optical connection port <NUM> for receiving connector <NUM> at the other end according to the concepts disclosed.

By way of explanation, the one or more connection ports <NUM> and the one or more securing feature passageways <NUM> are a portion of the shell <NUM>. Illustratively, <FIG> and <FIG> depict extender port <NUM> comprising a shell <NUM> comprising a body <NUM> with a first connection ports 236disposed on a first end or portion <NUM> and a second connection port <NUM>' disposed on an opposite end. Each connection port <NUM>,<NUM>' comprises a respective optical connector opening <NUM>. The optical connector openings extend from an outer surface <NUM> of shell <NUM> of the extender port <NUM> into a cavity <NUM> and define a respective connection port passageway <NUM>,<NUM>'. One or more respective securing feature passsageways <NUM> extend from the outer surface <NUM> of the shell <NUM> to cooperate with the respective connection port passageways <NUM>, <NUM>'. The second connection port passageway (<NUM>') is aligned with the first connection port passageway (<NUM>) so that respective external connectors <NUM> may be optical mated using the extender port <NUM>. As depicted in <FIG>, shell <NUM> is formed by a first portion 210A and a second portion 210B, but other arrangements are possible for shell <NUM>.

<FIG> is an exploded view showing the second portion 210B of shell <NUM> removed from the first portion 210A and showing the internal assembly of extender port <NUM>. <FIG> show the assembly of the extender port <NUM> of <FIG>. <FIG> shows a longitudinal cross-section through the connection port passageway <NUM> of an assembled extender port <NUM> with no connectors attached.

As shown in <FIG>, securing feature <NUM> is biased to a retain position. Specifically, the securing feature <NUM> is biased in an upward direction using a securing feature resilient member 310R that is positioned between the securing feature <NUM> and shell <NUM>. Consequently, a portion of securing feature <NUM> is capable of translating within a portion of the securing feature passageway <NUM>. As depicted, a sealing feature <NUM> is disposed on the securing feature <NUM>. Sealing feature <NUM> provides a seal between the securing feature <NUM> and the securing feature passageway <NUM> to inhibit dirt, dust and debris from entering the device.

As best depicted in <FIG>, this connection port passageway <NUM> may comprise a keying portion 233KP as part of the extender port <NUM>. As shown, keying portion 233KP is disposed forward of the securing feature <NUM> (i.e., before) in the connection port passageway <NUM> upon entry of the passageway. The keying portion 233KP may have any suitable location in the connection port passageway <NUM> forward of the securing feature. As depicted, the extender port <NUM> has the securing features <NUM> associated with each connection port passageway <NUM> that cooperate with a portion of the securing feature passageway <NUM>. In this embodiment, the securing feature <NUM> is a pushbutton actuator formed as a single component with the locking feature <NUM>.

Extender port may also have a keying portion 233KP disposed on the optical connector opening <NUM> side of the securing feature <NUM>. Keying portion 233KP inhibits the insertion of a non-compliant connector into connection port <NUM>, thereby inhibiting damage that may be caused to the device. Suitable connectors <NUM> have a complimentary keying feature that cooperates with the keying portion 233KP of extender port <NUM>. Keying portion 233KP may be a protrusion or additive feature disposed within the connection port passageway <NUM> on the optical connector opening <NUM> side of the securing feature <NUM> and may take several different configuration if used. For instance, keying portion 233KP may be a simple protrusion as shown. In other embodiments, the keying portion 233KP may take the shape of a D-shaped opening to allow only a suitable connector <NUM> having a complimentary feature to be inserted into the connection port <NUM>. The keying portion 233KP may also aid with blind mating a connector <NUM> into the connection port <NUM> since it only allows further insertion into the connection port <NUM> when the connector is in the proper rotational orientation.

Extender port <NUM> of <FIG> also comprises at least one adapter assembly 230A aligned with one or more of the respective connection ports <NUM> when assembled. Adapter assembly 230A is suitable for aligning the respective ferrules of connectors <NUM> that are inserted into connection ports <NUM>. Adapter assembly 230A may comprise a ferrule sleeve 230FS, an adapter housing formed from one or more components <NUM>, and a resilient member 230R as shown in <FIG> and <FIG>. Ferrule sleeve 230FS receives a portion of the respective ferrule 10F of connectors <NUM> for precision alignment.

<FIG> depict the assembly of extender port <NUM> of <FIG>. <FIG> depicts the securing feature <NUM> being aligned for installation into the securing feature passageway <NUM> of the first portion 210A of shell <NUM>. As depicted, keying features <NUM> of securing feature <NUM> (<FIG>) are aligned with the features of the securing feature passageway <NUM>, which only allow assembly in one orientation for the correct orientation of the locking feature <NUM> in the extender port <NUM>. <FIG> also shows adapter 230A in an exploded view before being aligned and installed into the saddle 210D of first portion 210A of shell <NUM>. Once seated, the resilient member 230R of adapter 230A biases the housing <NUM> components outward and provides the ability for the ferrule sleeve 230FS or adapter 230A to "float" relative to the shell <NUM>. "Float" means that the adapter 230A can have slight movement in the X-Y plane for alignment, and may be inhibited from over-traveling in the Z-direction along the axis of connector insertion so that suitable alignment may be made between mating connectors. Once the adapter 230A is installed into first portion 210A, the biasing force on housing components <NUM> holds the adapter 230A in place until the second portion 210B of shell <NUM> is attached as depicted in <FIG>.

In other embodiments, adapters 230A may be formed from several components, but some adapters or portions thereof could be integrally formed with the extender port as well.

<FIG> depicts is a partial assembled view of extender port <NUM> showing adapter 230A installed into the first portion 210A of the shell <NUM>, and the respective securing feature resilient members 310R placed on a bottom portion of securing feature <NUM> before the second portion 210B of shell <NUM> is attached to trap the securing feature resilient members 310R in place. Securing feature <NUM> may have a bottom recess 310BR or ring for seating the securing feature resilient members 310R and centering the restoring force on the securing feature <NUM> as best shown in <FIG>. Thereafter, the second portion 210B of shell <NUM> may be attached to the first portion 210A is a suitable fashion using a sealing element <NUM> or not.

In this embodiment, the securing feature <NUM> comprises a bore 310B that is aligned with the least one connection port passageway <NUM> when assembled as best shown in <FIG>. Bore 310B is sized for receiving a suitable connector <NUM> therethrough for securing the same for optical connectivity. Bores or openings through the securing feature <NUM> may have any suitable shape or geometry for cooperating with its respective connector. As used herein, the bore may have any suitable shape desired including features on the surface of the bore for engaging with a connector for securing the same.

In some embodiments, the securing feature <NUM> is capable of moving to an open position when inserting a suitable connector <NUM> into the connection port passageway <NUM>. When the connector <NUM> is fully-inserted into the connector port passageway <NUM>, the securing feature <NUM> is capable of moving to the retain position automatically. Consequently, the connector <NUM> is secured within the connection port <NUM> by securing feature <NUM> without turning a coupling nut or a bayonet like the prior art devices. Stated another way, the securing feature <NUM> translates from the retain position to an open position as a suitable connector <NUM> is inserted into the connection port <NUM>. Then, when connector <NUM> is fully-seated the securing feature <NUM> is biased back to the retain position to secure the connector <NUM> in the connection port <NUM>. The securing feature passageway <NUM> is arranged transversely to a longitudinal axis LA of the extender port <NUM>, but other arrangements are possible. Other securing features may operate in a similar manner, but use an opening instead of a bore that receives the connector therethrough.

As shown in <FIG>, securing feature <NUM> comprises a locking feature <NUM>. Locking feature <NUM> cooperates with a portion of the connector <NUM> when it is fully-inserted into the connection port <NUM> for securing the same. Specifically, the connector housing <NUM> of connector <NUM> may have a cooperating geometry that engages the locking feature <NUM> of securing feature <NUM>. In this embodiment, securing feature <NUM> comprise a bore 310B that is respectively aligned with the respective connector port passageway <NUM> as shown in <FIG> when assembled. The bore 310B is sized for receiving a portion of connector <NUM> therethrough. <FIG> are longitudinal cross-sectional views of extender port <NUM> depicting the optical connection port <NUM> of the extender port <NUM> with a connector <NUM> retained therein.

As depicted in this embodiment, locking feature <NUM> is disposed within bore 310B. Specifically, locking feature <NUM> comprises a ramp in this embodiment. The ramp is integrally formed at a portion of the bore 310B with the ramp angling up when looking into the connection port <NUM>. The ramp allows the connector <NUM> to push and translate the securing feature <NUM> downward against the securing feature resilient member 310R as the connector <NUM> is inserted in the connection port <NUM> as shown. Ramp may have any suitable geometry such as a retention surface such as a ledge at the backside or the ramp may lead to a flat portion before the retention surface. Once the locking feature <NUM> of the securing feature <NUM> is aligned with the cooperating geometry of the locking feature <NUM> of connector <NUM>, then the securing feature <NUM> translates so that the locking feature <NUM> engages the locking feature <NUM> of connector <NUM> as shown in <FIG>. Detailed views of the securing feature <NUM> of <FIG> are shown in <FIG>.

The sealing between the components of shell <NUM> may comprise a sealing element (not visible) disposed between the components. The sealing may comprise a groove in one portion of the shell that cooperates with a tongue on the other portion of the shell <NUM>. Grooves may extend about the perimeter of sealing surface. Grooves may receive one or more appropriately sized O-rings or gaskets for weatherproofing extender port <NUM>. The O-rings are suitably sized for creating a seal between the components of the shell <NUM>. By way of example, suitable O-rings may be a compression O-ring for maintaining a weatherproof seal. Other embodiments may use an adhesive or suitable welding of the materials such as ultrasonic or induction welding with appropriate materials for sealing the extender port <NUM>.

<FIG> depicts a perspective view showing details of the second portion 210B of shell <NUM> of <FIG>. Second portion 210B of shell <NUM> comprises at least one pin 210P disposed within a securing member pocket 210SP. The pin 210P and the securing member pocket 210SP cooperate to align and seat the resilient member 310R between the second portion 210B of shell <NUM> and the securing feature <NUM> for biasing the securing feature <NUM> to a retain position.

In this embodiment, shell 210B also comprises a tongue 210T near an outer periphery that may cooperate with a groove <NUM> construction on the first portion 210A of the shell <NUM> for alignment and/or sealing of the device. The interface between components of the shell may have other structure or features for securing or sealing the components such as fasteners for securing the components of the shell or an adhesive, o-ring or gasket or weldable feature for sealing. Shells <NUM> may have any suitable shape, design or configuration as desired. Shells <NUM> may comprise at least one rib or support <NUM>, thereby providing crush support for the extender port <NUM> and resulting in a robust structure. Further, shells <NUM> may comprise more than two portions if desired. Likewise, multiple portions of the shell <NUM> may comprise connection ports <NUM>.

Any of the extender port <NUM> disclosed herein may optionally be weatherproof by appropriately sealing seams of the shell <NUM> between components using any suitable means such as gaskets, O-rings, adhesive, sealant, welding, overmolding or the like. Moreover, the interface between the connection ports <NUM> and the dust cap or connector <NUM> may be sealed using appropriate geometry and/or a sealing element such as an O-ring or gasket <NUM> on the connector or dust cap. If the extender port <NUM> is intended for indoor applications, then the weatherproofing may not be required.

Extender port <NUM> may also comprise integrated mounting features. By way of explanation, shell <NUM> may have mounting features configured as passageways disposed on the lateral sides. Thus, the user may simply use a fastener such as a zip-tie threaded thru these lateral passageways for mounting the extender port <NUM> to a wall or pole as desired.

As shown in <FIG>, the connector mating plane 230MP between the ferrules 10F of connectors <NUM> is disposed within the cavity <NUM> extender port <NUM>. Connectors <NUM> includes a locking feature <NUM> on the housing <NUM> for cooperating with a securing feature <NUM> of extender port <NUM>. Additionally, the connection ports <NUM>,<NUM>' comprise a suitable length L between locking features <NUM> associated with the connection ports <NUM>,<NUM>' so that the connectors <NUM> may have the proper amount of "float" for suitable optical performance. Connector <NUM> may comprise at least one O-ring <NUM> for sealing with the connector port passageway <NUM> at a sealing surface 233SS when the connector <NUM> is fully inserted into the connection port <NUM>. Illustratively, connection port <NUM> has connection port passageway sealing surface 233CS for the connector <NUM> disposed at a distance D3 from the mating plane 230MP of the connectors <NUM>. Distance D3 is farther from the mating plane <NUM> MP than the locking feature <NUM> of securing feature <NUM>. The tolerance stack-up of components between the locking features <NUM> in the disctance L should be managed to allow a suitable connector-to-connector interface with the mating ferrules.

<FIG> depict detailed perspective views of the securing feature <NUM> shown by the explanatory device of <FIG>. Locking feature <NUM> comprises a retention surface 310RS. In this embodiment, the back-side of the ramp of locking feature <NUM> forms a ledge that cooperates with complimentary geometry on the connector housing <NUM> of connector <NUM>. However, retention surface 310RS may have different surfaces or edges that cooperate for securing connector <NUM> for creating the desired mechanical retention. For instance, the retention surface 310RS may be canted or have a vertical wall for tailoring the pull-out force for the connection port <NUM>. However, other geometries are possible for the retention surface 310RS. Additionally, the connection port <NUM> has a sealing location at a connection port passageway sealing surface with the connector <NUM> that is located closer to the optical connector opening <NUM> at the outer surface <NUM> than the securing feature <NUM> or locking feature <NUM>.

Securing feature <NUM> may also comprise other features as best depicted in <FIG>. For instance, securing feature <NUM> may include a sealing member <NUM> disposed above the connector port passageway <NUM> for keeping dirt, debris and the like out of portions of the extender port <NUM>. Sealing member <NUM> is sized for the retention groove 310RG in the securing feature <NUM> and the securing feature passageway <NUM> for sealing.

Securing feature <NUM> may also comprises one or more guides <NUM> that cooperate with the shell <NUM> for keeping the bore 310B in the proper rotational orientation within the respective securing feature passageway <NUM> during translation. In this embodiment, two guides <NUM> are arranged about <NUM> degrees apart and guide the translation of the securing feature <NUM>. Securing feature <NUM> may also comprise one or more keys <NUM> that cooperate with the shell <NUM> or connection port insert <NUM> for only allowing one assembly orientation into the shell <NUM> or connection port insert <NUM>, thereby keeping the locking feature <NUM> in the proper position within the respective securing feature passageway <NUM> with respect to the connector insertion direction.

Securing feature <NUM> may also comprise a stop surface 310SS for inhibiting overtravel or the securing feature <NUM> from being removed from the extender port <NUM> when assembled. In this embodiment, the stop surface 310SS is disposed as the top surface of guides <NUM>. Securing feature <NUM> may also include a dimple <NUM> or other feature for inhibiting inadvertent activation/translation of the securing feature <NUM> or allowing a tactical feel for the user. Securing features <NUM> may also be a different color or have a marking indicia for identifying the port type.

As best shown in <FIG>, locking feature <NUM> is configured as ramp 310RP that runs to a short flat portion, then to a ledge that reverts to a round cross-section for creating the retention surface 310RS for engaging and retaining the connector <NUM> once it is fully-inserted into the connector port passageway <NUM> of the connection port <NUM>. Consequently, the securing feature <NUM> is capable of moving to an open position (OP) when inserting a suitable connector <NUM> into the connector port passageway <NUM> since the connector housing <NUM> engages the ramp 310RP pushing the securing feature downward during insertion.

The securing feature <NUM> translates from a retain position (RP) to an open position (OP) as a suitable connector <NUM> is inserted into the connection port <NUM>. Once connector <NUM> is fully inserted into connector passageway <NUM>, then the securing feature <NUM> automatically moves to the retain position (RP) since it is biased upwards to the retain position. This advantageously allows a plug and play connectivity of the connectors <NUM> with extender port <NUM> without having to turn a coupling nut or a bayonet like conventional devices. Thus, connections to the extender port may be made faster and in positions that may be awkward with relative ease.

Still other types of securing members <NUM> may operate in a similar manner for securing connector <NUM>, but comprise more than one component such as an actuator 310A that cooperates with a securing member <NUM> such as disclosed herein with other embodiments. Additionally, the use of more than one component may allow other arrangements for the securing feature passageway <NUM> relative to a longitudinal axis LA of the device.

To make identification of the connection ports or easier for the user, a marking indicia may be used such as text or color-coding of extender port or marking the input tether (e.g. an orange or green polymer) or the like.

Any of the extender ports <NUM> may also have one or more dust caps (not shown) for protecting the connection port <NUM> from dust, dirt or debris entering the extender port or interfering with the optical performance. Thus, when the user wishes to make an optical connection to the extender port, the appropriate dust cap is removed and then connector <NUM> of cable assembly <NUM> may be inserted into the respective connection port <NUM> for making an optical connection to the extender port <NUM>. Dust caps may use similar release and retain features as the connectors <NUM>. By way of explanation, when securing feature <NUM> is pushed inward or down, the dust cap is released and may be removed.

Other variations of extender ports <NUM> are possible according to the concepts disclosed. By way of example, Extender ports <NUM> of <FIG> and <FIG>are similar to extender port <NUM> of <FIG>, except they use other mechanisms with the securing feature <NUM>, wherein Extender ports <NUM> of <FIG> are not covered by the scope of the appended set of claims. <FIG> depict another explanatory fiber optic extender port <NUM> according to the concepts disclosed. Extender port <NUM> of <FIG> is similar to extender port <NUM> of <FIG>, except it uses a single securing member <NUM> having opposing locking features <NUM>. Using two locking features <NUM> on a common datum of the securing member <NUM> of <FIG> provides easier control of the length L between locking features <NUM> compared with the tolerance stack-up of multiple components Individual actuators 310A (i.e., two) for cooperating with securing member <NUM> for releasing and mating the connection ports <NUM>. Like extender port <NUM> of <FIG>, resilient members 310R bias securing member <NUM> upwards to a retain position at each end for the respective connection ports <NUM>, thereby providing a normally locked position for the connection port <NUM>. To release the locking feature <NUM> of securing member <NUM> of <FIG>, either one of the actuator 310A may be pushed downward for translating one end of the securing member <NUM> downward and moving the locking feature <NUM> to a release position.

<FIG> and <FIG> depict partially exploded views of the extender port <NUM> showing details of the construction, and <FIG> shows an assembled view with the second portion 210B removed. This extender port <NUM> has biased securing features that operates in a similar manner as the other extender ports disclosed. However, this extender port <NUM> uses a securing feature <NUM> with a common securing member <NUM> comprising two locking features <NUM> for avoiding the tolerance stack-up of multiple components in the device for helping preserve optical performance. With reference to <FIG>, the two locking features <NUM> on the common securing member <NUM> are positioned at the desired distance L to allow a suitable connector-to-connector interface between the mating ferrules; and the tolerances and ferrule travel of the connectors may be considered as well. Opposing locking features <NUM> are molded on a common securing member <NUM> as depicted in <FIG>. Locking features <NUM> of the common securing member <NUM> may have suitable geometry for securing connectors such as described herein.

Actuator 310A cooperates with respective securing feature passageways <NUM> formed as a portion of the first portion 210A of shell <NUM> as discussed herein. Actuators 310A also comprise push arms 310PA that are spaced apart for allowing a portion of the connector <NUM> to pass therethrough for mating as best shown in <FIG>. When assembled, push arms 310PA contact portions of the securing member <NUM> adjacent to locking feature as shown and translating the actuator 310A downwards translates the locking feature <NUM> to a release position.

Like the extender port <NUM> of <FIG>, securing features <NUM> may translate in a vertical direction as represented by the arrows in <FIG> for retaining and releasing connector <NUM> in extender port <NUM>. As depicted, the resilient members 310R are disposed below the securing member <NUM> for biasing the ends of the securing member <NUM> (and the actuators 310A) upwards to a normally retained position (RP). Securing feature <NUM> further includes a locking feature <NUM>.

A simplified adapter assembly 230A is used in this embodiment that comprises a ferrule sleeve 230FS for precision alignment of mating ferrules between connectors <NUM> that is disposed within adapter housing <NUM> without a resilient member. <FIG> depicts the extender port <NUM> fully-assembled.

Devices may have other constructions for the securing features <NUM> that use more than one component. Illustratively, <FIG> depict another extender port <NUM> not covered by the scope of the appended set of claims that comprises a connection port <NUM> as a portion of the shell <NUM> with securing features <NUM> comprising more than one component. This extender port is similar to the construction described, and the description of this device with the securing feature <NUM> comprising more than one component will describe differences in the designs for the sake of brevity, and other features are similar to those disclosed.

Extender port <NUM> of <FIG> uses securing features <NUM> comprising an actuator 310A and a securing feature member <NUM>. Specifically, securing feature member <NUM> comprises an opening may be elastically deformed by actuator 310A (or other structure) when pushed (or upon insertion of a suitable connector <NUM> into connection port <NUM>) and the securing feature member <NUM> springs back to engage a suitable portion of connector <NUM> such as loking feature <NUM> of connector housing <NUM>
when the actuator 310A is released or when connector <NUM> is fully-seated within the connection port <NUM> as will discussed in more detail. As best shown in <FIG>, the securing member <NUM> comprises a locking feature <NUM> formed by one or more arms 310AM.

<FIG> are partial assembled views with portions of a securing feature sub-assembly 310SA removed as discussed below for disclosing the construction and operation of the securing feature <NUM>. As depicted in <FIG>, the securing member <NUM> may be placed into a housing formed by one or more housing portions 310HH for maintaining the proper orientation of the securing features within shell <NUM>. The securing feature sub-assembly 310SA also allows for easier assembly of securing members <NUM> into the shell <NUM> of extender ports <NUM>. In other words, the housing portions 310HH may have suitable geometry for keeping the securing members in the desired orientation. The right-side of <FIG> depicts the securing feature sub-assembly 310SA assembled and placed into the second portion 210B of shell <NUM>. For instance, the second portion 210B may have a pocket or other alignment feature for seating the securing feature sub-assembly 310SA. The left-side of <FIG> depicts the securing member <NUM> and the actuator 310A without the housing portions 310HH to show the engagement with the locking features on the connector <NUM>. Consequently, the actuators 310A are aligned and positioned with respective securing members <NUM> of the securing features.

<FIG> is a detailed perspective view showing the securing member <NUM> disposed within the components <NUM> of 310SA and the adapter assembly 230A removed to show the mating of complimentary ferrules 10F of connectors <NUM>. Specifically, the arms of the securing member <NUM> engage a locking feature <NUM> (e.g., a groove) that is integrally-formed on the housing <NUM> of the connector <NUM>. <FIG> is a detailed perspective view similar to <FIG>, but the adapter assembly 230A is shown.

Securing feature <NUM> comprises actuator 310A and securing member <NUM>. Securing member <NUM> comprises an opening between its arms 310AM that may be elastically deformed by actuator 310A when translated (i.e., pushed) or upon insertion of a suitable connector <NUM> into connection port <NUM> by spreading (i.e., translating) the arms of the securing member <NUM> outward. When the actuator 310A is released or the connector is fully-seated within the connection port <NUM> or input port <NUM>, the arms 310AM of the securing member <NUM> springs back to engage a suitable portion of connector <NUM> such as locking feature <NUM> of connector housing <NUM> or move the actuator 310A to a normal position. The arms 310AM have an edge portion that act as a locking feature <NUM> for the suitable connector <NUM>. By way of explanation, the edge portions of arms 310AM engage the locking feature <NUM> of the connector housing <NUM> for securing the connector <NUM>. In order to release the connector <NUM> from the connection port <NUM>, the arms 310AM and locking features <NUM> on the arms 310AM are translated outward.

As best shown in <FIG>, actuator 310A comprises a wedge 310W that pushes into a head end <NUM> of securing member <NUM>, thereby elastically deflecting the arms 310AM of securing member <NUM> outward for releasing connector <NUM>. The securing member <NUM> or actuators 310A of securing feature <NUM> may comprise a variety of different constructions. Likewise, the securing features <NUM> comprising more than one component may be biased by a securing feature resilient member 310RM if desired. For instance, securing feature resilient member 310RM may bias the actuator 310A toward a secure position. In other embodiments, the securing feature resilient member may bias the securing member <NUM>.

<FIG> are various perspective views of the actuator 310A of the securing feature <NUM> of the extender port <NUM> shown in <FIG>. Actuator 310A may include a sealing member <NUM> disposed above the connector port passageway <NUM> for keeping dirt, debris and the like out of portions of the extender port <NUM>. Sealing member <NUM> is sized for the retention groove 310RG in the actuator 310A and the securing feature passageway <NUM> for sealing. Actuator 310A may also be shaped to have one or more guides <NUM> that cooperate with the shell <NUM> or connection port insert <NUM> for keeping proper rotational orientation of the wedge 310W within the respective securing feature passageway <NUM> during translation. In this embodiment, the shape of the flange aids in the rotational orientation. Actuator 310A may also comprise a stop surface 310SS for inhibiting over-travel or the actuator 310A from being removed from the extender port <NUM> when assembled. Actuator 310A may also be a different color or have a marking indicia for identifying the port type. For instance, the actuator 310A may be colored red for connection ports <NUM> and the actuator 310A for the input connection port <NUM> may be colored black. Other color or marking indicia schemes may be used for passthrough ports, multi-fiber ports or ports for split signals.

Thus, the securing feature member <NUM> of securing feature <NUM> is suitable for retaining connector <NUM> in connection port <NUM> as discussed herein. Various different embodiments are possible for securing features <NUM> comprising more than one component for the devices disclosed. <FIG> are various views of securing member <NUM> for explaining details of the design. <FIG> is a perspective view of the securing member blank for forming the securing feature <NUM> depicted in <FIG>. Securing member <NUM> may be formed from any suitable material such as a spring steel and have a suitable geometry for retaining a connector <NUM>. As depicted, securing member <NUM> comprises arms 310AM that define an opening (not numbered) therebetween along with a head end <NUM> formed at the ends of the arms 310AM. The opening (not numbered) between the arms 310AM is sized for cooperating with a suitable connector <NUM>. Arms 310AM may comprise tabs 310T that are curved for aiding the engagement of the connector <NUM> with the securing member <NUM> upon insertion and allowing a smoother pushing and translation of the arms 310AM outward as connector <NUM> is inserted into connection port <NUM>. Likewise, the head end <NUM> may also be formed with a suitable shape that cooperates with the actuator 310A. Like the other securing features <NUM>, the securing feature <NUM> may comprises more than one component for translating from a retain position (RP) to an open position (OP) as a suitable connector <NUM> is inserted into the connection port <NUM>. Once connector <NUM> is fully-inserted into connector passageway <NUM>, then the securing feature <NUM> automatically moves to the retain position (RP) since the arms 310AM are biased to the retain position. This advantageously allows a push and play connectivity of the connectors <NUM> with extender port <NUM> without having to turn a coupling nut or a bayonet like conventional devices. Thus, connections to the extender port may be made faster and in positions that may be awkward with relative ease.

Securing features <NUM> comprising more than one component may have various other configurations for use with devices disclosed herein. <FIG> depict perspective views of another securing feature <NUM> comprising securing member <NUM> for use with an actuator 310A. In this embodiment, the securing member <NUM> is inverted so that the head end <NUM> cooperates with a portion of the extender port shell for translating the arms 310AM outward compared with other embodiments. More specifically, a portion of the extender port such as connector port insert of shell comprises a wedge for translating the arms 310AM outward when the actuator 310A translates downward.

<FIG> is a front view of still another securing feature <NUM> comprising securing member <NUM> for use with an actuator 310A that provides a reduced height compared with other embodiments. This securing member <NUM> comprises arms 310AM that define an opening (not numbered) therebetween along with a head end <NUM> formed at the ends of the arms 310AM. Head end <NUM> of this securing member <NUM> has the ends curled in and downward and the actuator 310A positions the wedge 310W further upward into the acutator 310A footprint as shown in <FIG> resulting in a construction that has a reduced height and allowing the device to reduce its height as well.

Still other variations of the concepts disclosed are possible. Securing features <NUM> may have any suitable orientation or construction for engaging connectors <NUM>. Securing feature <NUM> may be arranged at an angle relative to the longitudinal axis LA of the connection port <NUM>. By way of example, the securing feature <NUM> may comprises securing member <NUM> and actuator 310A disposed in a securing feature passageway <NUM> that is angled with respect to the longitudinal axis LA of the connection port <NUM>. Likewise, connector <NUM> has a connector housing <NUM> with the locking feature <NUM> that is angled with respect to the longitudinal axis of the connector. Similar concepts may be used with as a portion of the shell or the connection port insert as well as a monolithic securing feature <NUM>.

It may be advantageous to organize extender ports <NUM> in arrays. <FIG> depicts an organizer <NUM> comprising a passageway 400P and one or more guides <NUM>. Organizer <NUM> is sized for receiving a plurality of extender ports <NUM> for providing organization for an array of devices as shown in <FIG>. Extender ports <NUM> are aligned with in the passageway 400P and have a friction fit with the organizer <NUM>.

Organizers <NUM> can have a variety of shapes and configurations. <FIG> depicts another organizer <NUM> comprising segregated passageways 400P disposed on opposite sides of a common wall. The passageways 400P have an open side <NUM> and the ends of the common wall have snap-fit features <NUM> for securing extender ports <NUM> to the organizer <NUM> as shown in <FIG>.

<FIG> depicts yet another organizer <NUM> comprising passageway 400P with open side <NUM>. Organizer <NUM> comprises snap-fit features <NUM> for securing extender ports <NUM> to the organizer <NUM> as shown in <FIG>.

The present application also discloses methods for making extender ports. One method of making an extender port comprises providing a shell <NUM> comprising a first connection port <NUM> having an optical connector opening <NUM> and a connection port passageway <NUM>. The method includes assembling at least one securing feature so it is associated with a connection port passageway of the shell securing, and installing at least one securing feature resilient member for biasing a portion of the at least one securing feature.
