CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a divisional of U.S. application Ser. No. 12/855,973, filed on Aug. 13, 2010 now U.S. Pat. No. 8,368,533, the disclosure of which is incorporated herein by reference. 
    
    
     BACKGROUND OF THE INVENTION 
     An optical fiber is made up of a core, cladding, and a buffer coating. The core carries light pulses, the cladding reflects the light pulses back into the core, and the buffer coating protects the core and cladding from moisture, damage, etc. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths than other forms of communications. Such fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Optical fibers are also used for illumination, and are wrapped in bundles so they can be routed together, thus allowing illumination of tight spaces. 
     Today, optical fibers are widely used by communication services to route data to individual homes. For example, telephone companies, cable television companies, and internet service providers (ISPs) often utilize fiber optic cables to transmit data to a subscriber&#39;s home. However, running the fiber optic communication lines to the subscriber&#39;s home can be very time consuming and expensive. For example, in some residential areas, telephone and other communication lines are run aerially via telephone poles. In these areas, connections are made from the aerial line to a point in the user&#39;s home. This connection may require trained installers to route the aerial line down an exterior wall of the home, drill a hole in the wall, run the line through the house, etc. Other residential areas require communication lines to be run underground, for example, beneath roadways. Connecting these lines to a home may require digging up enough ground to locate the communication line, and then digging a path from the communication line to the user&#39;s home to run an adjoining line. Additionally, joining lengths of optical fiber is more complex than joining electrical wire or cable. The ends of the fibers must be carefully cleaved, and then spliced together either mechanically or by fusing them together with an electric arc. Special connectors are used to make removable connections. 
     SUMMARY OF THE INVENTION 
     One aspect of the disclosure provides a system for data communication connection in an architecture including an optical fiber communication line running from a communication service provider source to a proximity of a building, a fiber optic branch line extending from a point along the communication line generally towards the building, and a receptacle disposed at an end of the fiber optic branch line.

The communication unit may include a visual indicator. The system further comprises a fiber optic cable coupled to the communication unit, and at least one connector adapted to couple the branch line to the fiber optic cable coupled to the communication unit, the connector residing within the receptacle. The visual indicator of the communication unit provides a visual indication that coupling of the branch line and the fiber optic cable is effected, and the fiber optic cable relays the visual indication from the visual indicator to an opposing end of the fiber optic cable. 
     The visual indication may comprise illumination of a light emitting diode, such as one of a plurality of different colored light emitting diodes disposed on the communication unit. The connector may comprise a window for viewing the visual indication relayed to the opposing end of the fiber optic cable. According to one embodiment, a displacement box may be coupled between the communication unit and the branch line. The communication line, branch line, and receptacle may be located underground.

     According to one aspect, the above-described method may further comprise coupling the branch line to the cable via the at least one connector, and receiving a visual indication at an area proximal to the coupling of the branch line and the cable. This visual indication may be transmitted by the communication unit in response to the coupling of the branch line to the cable. The method may further comprise providing a displacement box outside the building, and coupling the displacement box between the communication unit and the branch line. 
     An even further aspect of the disclosure provides a kit of component parts for facilitating data communication connection in an architecture including an optical fiber communication line running from a communication service provider source to a proximity of at least one building, a fiber optic branch line extending from a point along the communication line generally towards the at least one building, and a receptacle.

     DETAILED DESCRIPTION 
       FIG. 1  illustrates a scenario according to an aspect of the disclosure. As shown, a house  110  sits on a lot  112 , which is separated from roadway  116  by a curb  114 . Communication line  150  runs underneath the roadway  116 . However, communication line  150  may also be run overhead, depending on zoning regulations where the house  110  is located, etc. The communication line  150  may be any type of line transmitting any type of information, such as voice, data, etc. For purposes of the present example we assume that the communication line  150  is a fiber optic line. 
     Rather than running a line from communication line  150  directly to the house  110 , as in conventional systems, the communication line  150  is run to a receptacle  160  via branch line  155 . The receptacle  160  may be an underground hand-hole which houses a connector to the fiber optic communication line  150 . It may be placed anywhere between the curb  114  and the house  110 . A most cost-effective placement of the receptacle  160  may be on the lot  112  just inside the curb  114 . 
     The receptacle  160  may be any type of housing for electronic components. For example, it may be any shape, such as cylindrical, cubical, etc., and it may be made of any material, such as plastic, metal, etc. It may be disposed above ground, for example, in an above-ground electrical box on a pole, on a roof, on an exterior wall of a house, etc. Alternatively, it may be disposed underground, as shown in  FIG. 1 . 
     Inside the receptacle  160 , the branch line  155  may terminate in a connector, such as connector  370  shown in  FIG. 3 . The connector may be adapted to receive an end of a fiber optic cable. Alternatively, the connector may be adapted to receive a complementary connector attached to the end of the fiber optic cable. 
     As shown in  FIG. 2 , a communication unit, such as an optical network termination (ONT) device  230 , resides within the house  210 . The ONT device  230  may be an Internet connection device, such as a router or a modem, or any other communication terminal, such as a telephone, a television set-top box, etc. The ONT device  230  may be connected to the communication line  250  at the receptacle  260 . For example, such connection may be performed by an owner or resident of the house  210 , or it may be outsourced to a company providing such connection services. 
     According to one aspect of the disclosure, the ONT device  230  may be connected to the communication line  250  through a displacement box  240  residing on an exterior of the house  210 . For example, the ONT device  230  inside the house  210  may be connected to the displacement box  240  via a connection  235 , such as a fiber optic connection. An exterior line  245  may then be run from the displacement box  240  to the receptacle  260  to establish a connection between the ONT device  230  and the communication line  250 . 
     The displacement box  240  may facilitate connection to the receptacle  260  in several regards. For example, the displacement box  240  enables the exterior line  245  to be completely outside the house  210 , and thus it may be run underground. This eliminates a risk of disturbance of the exterior line  245  from individuals in the house  210 . Further, the displacement box  240  shortens the required distance of the wired connection  235  from the ONT device  230 . Such shortened required length also serves to reduce a risk of disconnection of the ONT device  230  from the communication line  250 . Even further, the displacement box  240  enables multiple ONT devices  230  within the house  210  to be connected to the communication line  250  without running a separate cable from each to the underground receptacle  260 . 
     According to one aspect of the disclosure, at least one of the ONT device  230  and the displacement box  240  may include an indicator, such as an indicator light, which indicates whether a connection between the ONT device  230  and the communication line  250  is complete. For example, the indicator light may include a red light emitting diode (LED) to indicate that the connection is incomplete, and a green LED to indicate that the connection is complete in the form of separate LEDs or a single bi-color LED. In this regard, a user running the connection from the ONT device  230  to the receptacle  260  will be able to visually determine if the ONT device  230  is operating disconnected from the communication line  250 . Data communications between the ONT device  230  and the communication line  250  should remain unaffected by the presence of the indicator light. 
     According to another example, the indicator may be any other type of indicator, such as an aural indicator. For example, the indicator may emit one sound or pattern of sounds when connection between the ONT device  230  and the communication line  250  is complete, and another sound or no sound when the connection is incomplete. 
     In the example where connection  235  and exterior line  245  are fiber optic cables, a color of the indicator light may be seen at a tip of the fiber optic cable when an opposing end is connected to the ONT device  230 . For example, when the cable is connected to the ONT device  230  at one end, but is not connected to the connector line  255  in the receptacle  260 , the red indicator light may be carried through the fiber optic cable(s) to the tip where it is visible. 
       FIGS. 3 and 4  demonstrate this concept. As seen in  FIG. 3 , ONT device  330  includes an indicator light  332 . Connected to the ONT device  330  proximal to the indicator light  332  is fiber optic cable  345 . For example, the indicator light  332  may be coupled to an input/output port for receiving the fiber optic cable  345 . As mentioned above, the cable  345  may include a connector at its distal end, such as male connector  380 . The male connector  380  may be structured such that light from the indicator  332  may be seen through the male connector  380 . For example, as shown in  FIG. 3 , the connector  380  includes a transparent portion  385  near a tip thereof to enable light traveling through the fiber optic cable  345  to be visible through the transparent portion  385 . 
     Inside receptacle  360 , communication line  355  terminates at a connector  370 . The communication line connector  370  may be adapted to receive an end of the cable  345 , or may be adapted to receive a complementary connector. For example, communication line connector  370  may be a female connector adapted to engage male connector  380 . 
     According to one aspect, the communication line connector  370  may include a window  375  to allow light from the fiber optic cable  345  to be seen therethrough. For example, if the male connector  380  is inserted into the connector  370 , but not properly engaged, the indicator light  332  on the ONT device  330  may be red. This red light may travel through the fiber optic cable  345  and be seen at the tip  385  through the window  375  of the communication connector  370 . Accordingly, a user would be alerted that the connection was not complete. 
       FIG. 4  illustrates the example where fiber optic cable  445  and communication line connector  480  are properly engaged, thus providing an effective coupling therebetween. Accordingly, indicator light  432  on ONT device  430  may display a green light, indicating that connection between the ONT device  430  and the communication line  455  is complete. This green light may be transmitted through the fiber optic cable  445  and connector  480  to a tip thereof. Similar to the example of  FIG. 3 , communication line  455  may terminate in a communication line connector  470  inside receptacle  460 . The communication line connector may include window  475 , through which light from a tip of the cable  445  is visible. Thus, the green light emitted by the indicator  432  and transmitted through the cable  445  may be seen through the window  475 . In this regard, a user attempting to couple the ONT device  430  to the communication line  455  will receive visual affirmation that his efforts were successful. 
       FIG. 5  provides a block diagram of an ONT device  530 . The ONT device  530  includes an optical interface  590  which couples to the communication line (e.g., communication line  150  of  FIG. 1 ) via optical fiber  545 . The optical interface  590  may contain a laser transmitter and a photodiode receiver for data communications. The optical interface  590  may be coupled to one or more computing devices in a home, and may thus transmit information from the computing devices to other devices connected via the connection line  155  (e.g., any other computing device connected to the Internet). Similarly, the optical interface  590  may provide information transmitted through the communication line  150  to the one or more computing devices. 
     The ONT device  530  also includes visual indicator unit  532 . The visual indicator unit  532  may include one or more light emitters, such as light emitting diodes (LEDs). For example, the visual indicator unit  532  may include a bi-color LED, or a separate red LED for indicating that the ONT device  530  is not connected to the communication line  150 , and a green LED for indicating that the ONT device  530  is properly connected to the communication line  150 . Alternatively, the visual indicator unit  532  may be a bitmap or liquid crystal display (LCD) display screen or any type of electronic visual indicator. 
     The optical interface  590  and the visual indicator unit  532  may also be connected to a control unit  540 . The control unit  540  may be any type of processor or other device capable of executing instructions. For example, the control unit  540  may be programmed to switch the bi-color LED in the visual indicator unit  532  from red to green upon determining that the optical fiber  545  is connected to the optical interface  590  and the communication line  150 . The control unit  540  may detect such connection by, for example, laser light received from the optical interface  590 . 
     The visual indicator unit  532  may be connected to a local indicator  534  for the ONT device  530 . The local indicator may be, for example, a window on a face of the ONT device  530  providing information from the visual indicator unit  532 . The visual indicator unit  532  may be connected to the local indicator  534  via, for example, a light tube  542 . Accordingly, in the instance where the visual indicator unit  532  includes a red or green LED, the light tube  542  would route the red or green light from the visual indicator  532  to the local indicator  534 . 
     The visual indicator unit  532  may also be coupled to combiner  536 . For example, the visual indicator unit  532  and the WDM combiner  536  may be connected via light tube  544 . Also coupled to the combiner  536  may be the optical interface  590  and the optical fiber  545 . In this regard, the combiner  536  may combine laser light from the optical interface  590  with visible light from the light tube  544  to provide a visual indication from the visual indicator unit  532  through the optical fiber  545 . For example, when the visual indicator unit  532  illuminates a green LED to indicate that connection of the optical data interface  590  is complete, the combiner  536  may facilitate the transmission of the green light through the optical fiber  545 . According to one aspect, the combiner  536  may be a passive wavelength division multiplexed (WDM) combiner. Accordingly, the combiner would not need to be electrically powered. Moreover, it would be wavelength selective. For example, laser communications wavelengths in the infra-red could be combined with the visible LED light. 
     A method of connecting a communication line to a home using the above-described system is illustrated in  FIG. 6 . It should be understood that the steps of the method need not be performed in the particular sequence illustrated. Moreover, the steps need not all be performed by the same individual or entity. For example, while some steps may be performed by a communication service provider, other steps may be performed by a homeowner or an independent contractor. 
     In step  610 , a communication line, such as the line  150  is installed. As discussed, the communication line  150  may be installed in any of a variety of ways, such as aerially or underground. Accordingly, the communication line  150  may extend a great distance to provide coverage to multiple homes and neighborhoods. The communication line  150  is preferably comprised of one or more fiber optic cables. 
     In step  620 , a branch line, such as the branch line  155 , is connected to the communication line  150  and installed to extend to a predetermined point. The predetermined point may be on or close to a homeowner&#39;s property. At the predetermined point, a receptacle housing a terminal end of the branch line  155  may also be installed. For example, the receptacle may be an underground hand-hole, such as the receptacle  160 , with a cover protecting its contents while also providing access thereinto. 
     In step  630 , a cable is connected to an ONT device inside the home. The ONT device may be a modem, a television set-top box, or the like. Alternatively, the ONT device may be a separate unit that may be coupled to modems, set-top boxes, computing devices, televisions, telephones, or other data transmitting/receiving devices in a home. 
     The ONT device may include a visual indicator viewable by a user. Accordingly, when the ONT device is powered on, or when the cable is connected thereto, it may provide an indication of such to the user. Using an example discussed above, the indication may be a red LED which is illuminated. Accordingly, in step  640  it is determined whether a visual indication is provided to the user. If no such indication is provided, it may be that there is a problem with the ONT device or with the cable connected thereto. Accordingly, the user may troubleshoot in step  650  to identify the problem and correct it. However, if a visual indication is provided, the ONT device is operating correctly, and the method may proceed to step  660 . 
     In step  660 , the cable from the ONT device may be connected to the branch line terminating in the receptacle. For example, the cable may be run outside the home and along a path to the receptacle. The path may be an aerial path, an underground path, or any other type, such as a path above ground and secured along a driveway. The cable and the branch line  155  may be connected via one or more connectors. For example, a particular connector device may be used to secure each of the lines to each other. Alternatively, one or both of the lines may be terminated in a connector, as discussed with respect to  FIGS. 3-4 , for ease of interconnection with each other. 
     In step  670 , it may be determined whether a positive visual indication is given to indicate that the connection of the ONT device to the communication line (e.g., via the cable and the branch line) is complete. For example, referring back to  FIG. 2 , the visual indication from the ONT device  230  may be transmitted through the fiber optic cables  235  and  245  and viewable at an end of the cable  245  near the receptacle  260 . Thus, in the example where a visual indication of a red light is given in step  640 , this red light may pass through the cable and be viewed by the user at its distal end. However, when properly connected to the branch line  255  in the receptacle  260 , the ONT device  230  may detect the connection. For example, a signal from the communication line  250  may be received by the ONT device  230 . Accordingly, the ONT device  230  may display a different visual indication, such as a green light. This green light may similarly be transmitted through the fiber optic cable  235 ,  245  to be seen by the user at its distal end. If the user receives positive visual indication, the method may be ended as connection of the ONT device  230  is complete. However, if no positive visual indication is received (e.g., if the light at the distal end of the cable remains red), the user may attempt to reconnect the cable to the branch line  255 . 
     Thus, a user may easily acknowledge a successful connection without returning inside the home to check the ONT device or any other connected devices. This provides a significant advantage as it prevents wasted time and frustration of trying to determine whether the ONT device is properly connected. An additional advantage is that this acknowledgement may be provided without requiring any additional manipulation of the fiber optic cable or installation of additional equipment. Rather, the fiber optic cable may be connected from one or more devices within the home to the communication line in the roadway or overhead with relative ease. 
     According to an alternative aspect, a separate visual indicator may be disposed within the receptacle to facilitate connection of the ONT device and the communication line from the service provider. For example, an LED may be housed in the receptacle, and may be illuminated to indicate whether connection was successful. This LED may be powered by, for example, a battery within the receptacle or a separate electrical line run from the home. In this regard, any type of wire may be used to form the connections between the ONT device and the service provider, and the wire would not need to transmit light therethrough. 
     According to one aspect, various components may be provided together in a kit. For example, the ONT device, one or more fiber optic cables for coupling the ONT device to the branch line, and at least one connector adapted to couple the fiber optic cables to each other or to the branch line may be provided together in a kit to a customer of a telephone company, cable company, and/or ISP. Further, instructions for connecting these components may also be included in the kit. In this regard, connection of computers, modems, routers, televisions, telephones, and other devices in the user&#39;s home to a communication service provider source may be further facilitated. 
     Although the present invention has been described with reference to particular embodiments, it should be understood that these examples are merely illustrative of the principles and applications of the present invention. For example, while the invention has been described above with respect to residential establishments, it should be understood that the same principles, concepts, and applications may also be applied to commercial entities. Additionally, it should be understood that numerous other modifications may be made to the illustrative embodiments and that other arrangements may be devised without departing from the spirit and scope of the present invention as defined by the appended claims.
