- As demand for telecommunications increases, fiber optic networks are being extended in more and more areas. In facilities such as multiple dwelling units (MDU's), apartments, condominiums, businesses, etc., fiber optic distribution terminals are used to provide subscriber access points to the fiber optic network. Fiber optic distribution terminals are often installed at separate floors of an MDU and are connected to the fiber optic network through cables connected to a network hub. The length of cable needed between the fiber optic enclosure and the network hub varies depending upon the location of the fiber optic enclosure with respect to the network hub. As a result, there is a need for a fiber optic enclosure that can effectively manage varying lengths of cable. Cables are also used to interconnect the subscriber access points provided by the fiber distribution terminals with subscriber interface units (e.g., Optical Network Terminals) provided at subscriber locations (e.g., at each residence of an MDU). With respect to such fiber distribution systems, there is also a need for techniques to effectively manage excess cable length while also taking into consideration space constraints.
- One aspect of the present disclosure relates to a fiber distribution device including a rotatable arrangement about which a length of fiber optic cable is coiled. The fiber optic cable includes at least one optical fiber contained within a cable jacket. An optical splitter can be added to the fiber distribution device subsequent to deployment of the fiber distribution device (e.g., when service is requested) from the fiber distribution device.
- In some implementations, the optical splitter has a configuration that enables subsequent installation of the splitter in the device.
- In some implementations, the input of the optical splitter may include either an adapter port or a connector configured to be received at an adapter port.
- Another aspect of the present disclosure relates to a fiber distribution system including a fiber distribution hub and one or more fiber distribution devices that can be installed at different locations within a building. Both the hub and the device can be initially deployed without splitters.
- In certain implementations, the device can be deployed with no output adapters at which subscriber patch cords can be connected to the device.
- In certain implementations, the hub can be deployed with no output adapters at which cables dispensed from the devices can be connected to the hub.
- Optical splitters having adapter output ports can be incrementally installed at the hub and/or the devices.
- In certain implementations, the output splitters of the hub and devices are interchangeable with each other.

The splitter input region of other types of splitter modules includes an optical connector.
- In some examples, the input region is disposed at a notched region of the body so that a splitter input port or connector is inwardly recessed from the splitter output ports.
- The optical splitter held within the splitter body can have any of a variety of ratios (e.g., 1:2, 1:4, 1:8, 1:16, 1:32, 1:64, etc.). In certain examples, a first splitter module can have a first splitter body holding an optical splitter having a first split ratio (e.g., 1:4) and a second splitter module can have a second splitter body holding an optical splitter having a second split ratio (e.g., 1:8) wherein the first and second splitter bodies have the same dimensions. Some splitters can be 2:4 or 2:8, with two inputs and 4 outputs or eight outputs for each input.

- Another aspect of the present disclosure relates to a fiber distribution device including a length of fiber optic cable with a connectorized end matable to an adapter for connecting to either a fiber optic connector and a cable or a fiber optic splitter with a plurality of outputs. An optical splitter can be added to the fiber distribution device subsequent to deployment of the fiber distribution device (e.g., when service is requested) from the fiber distribution device. The optical splitter has a configuration that enables subsequent installation of the splitter in the device.

Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like structure.
- Referring to
FIG. 1A , an example fiberoptic distribution system 10 in accordance with the principles of the present disclosure is shown. The fiberoptic distribution system 10 is shown incorporated into a building, such as a multi-dwelling unit (MDU) 12, havingmultiple floors floor 12 a can be a basement. A riser 14 can run between thevarious floors 12 a-12 d. While depicted in an MDU, it will be appreciated that thefiber distribution system 10 can be used in other types of buildings and other types of applications. - The
fiber distribution system 10 is shown including afiber distribution hub 20 installed at thefloor 12 a (e.g., typically in the basement or lowest floor of the building). Thefiber distribution hub 20 is shown receiving at least onefeed fiber 22 routed from a service provider 21 (e.g., from a central office of a service provider). Thefiber distribution hub 20 can include ahousing 24 that is capable of receiving one or moreoptical splitters 26. Eachoptical splitter 26 is configured to split optical signals supplied to thefiber distribution hub 20 by thefeed fiber 22. In various implementations, an optical splitter mounted at thehub 20 can be a 1:2 splitter, a 1:4 splitter, a 1:8 splitter, a 1:16 splitter, a 1:32 splitter, and/or a 1:64 splitter. Outputs of theoptical splitter 26 can be optically connected to optical fibers routed to thevarious floors 12 b-12 d of the building. - The
optical splitters 26 can be incrementally installed at thehub 20 as service is needed. For example, thehub 20 may initially be devoid ofsplitters 26. When one or more subscribers request service, one ormore splitters 26 may be installed at thehub 20. In some implementations, thesplitters 26 have output pigtails extending therefrom that can connect at adapters to the optical fibers routed to thefloors 12 b-12 d. In other implementations, thesplitters 26 have output adapters configured to receive connectorized ends of the optical fibers routed to thevarious floors 12 b-12 d or intermediate fibers. The splitter input also may include a connectorized pigtail, an unconnectorized pigtail, or an adapter. Thehousing 24 can also enclose various structures for making optical connections between optical fibers of optical cables. For example, the housing can include a plurality of fiber optic adapters for connecting fiber optic connectors, splice trays for protecting optical splices between optical fibers, or other types of structures. - The
fiber distribution system 10 is shown includingfiber distribution terminals 30 at each of theupper floors 12 b-12 d.Fiber optic cables 40 interconnect thefiber distribution hub 20 and thefiber distribution terminals 30. Thefiber optic cables 40 can each include one or more optical fibers contained within a protective jacket. The optical fibers of thefiber optic cables 40 can be optically coupled to thefeed fiber 22 through theoptical splitter 26 at thehub 20. At thefiber distribution terminals 30, thefiber optic cables 40 can be optically coupled topatch cords 50, which can be routed (e.g., horizontally along the floor) to optical network terminals (ONT's) 60 or other types of interface devices (e.g., an interface box, an interface panel, etc.) corresponding to different subscriber locations (e.g., apartments, residences, offices, condominiums, etc.) on eachfloor 12 a-12 d. AnONT 60 is an active device that converts optical signals from the service provider to electrical signals used at the subscriber locations. - If the
fiber optic cables 40 contain single optical fibers, thenoptical splitters 70 can be provided in each of thefiber distribution terminals 30 for splitting signals carried by the optical fibers of thefiber optic cables 40. Thepatch cords 50 are optically coupled to thesplitters 70 to carry the split signals to the ONT's 60. In some implementations, theoptical splitters 70 splits the signals to connectorized pigtails housed within thefiber distribution terminals 30, which are routed to adapters mounted within thefiber distribution terminals 30. In other implementations, theoptical splitters 70 have output adapter ports at which thepatch cords 50 can be inserted to receive the split signals. In certain implementations, theoptical splitters 70 can provide a split ratio of at least 1:4. In one example, theoptical splitters 70 can provide a split ratio of 1:8. In another example, theoptical splitters 70 can provide a split ratio of 1:4. In another example, theoptical splitters 70 can provide a split ratio of 1:16. - The
patch cords 50 can include first and second connectorized ends 50 a, 50 b. In some implementations, the first connectorized ends 50 a are optically connected to the connectorized pigtails within thefiber distribution terminals 30 by fiber optic adapters within thefiber distribution terminals 30. In other implementations, the first connectorized ends 50 a are optically connected to splitter output adapters within thefiber distribution terminals 30. The second connectorized ends 50 b of thepatch cords 50 can be coupled to the ONT's 60. - In other examples, the
fiber optic cables 40 can each include a plurality of optical fibers that are optically connected to thefeed fiber 22. For such examples, thefiber distribution terminals 30 can include fan-out devices (e.g., fan-out modules) that separate the optical fibers of thefiber optic cables 40 routed to eachfiber distribution terminal 30 into a plurality of connectorized pigtails that can be optically connected to subscriber locations viapatch cords 50 as described above. The ends of thefiber optic cables 40 that interface with thefiber distribution hub 20 can be terminated with multi-fiber fiber optical connectors. In this type of example, all of the optical splitting of the building can be accomplished at thefiber distribution hub 20. In contrast, the previous example uses a distributed optical splitting strategy where optical splitting can occur at thefiber distribution hub 20 and/or at each floor 12 b-12 d. - In some implementations, all of the components of the
fiber distribution system 10 are installed within theMDU 12 simultaneously. In other implementations, however, some of the components are initially installed and other components are installed only after those components are needed for service. For example,FIG. 1B shows thefiber distribution system 10 after an initial installation but prior to a service request from any of thefloors 12 b-12 d in accordance with some implementations. Thefiber optic cables 40 are routed from thefiber distribution terminals 30 to thehub 20. However, none of thefiber distribution terminals 30 includeoptical splitters 70 and nopatch cords 50 have been installed. When service is requested by one of the ONT's 60, asplitter 70 can be installed at the correspondingfiber distribution terminal 30 and apatch cord 50 can be routed between thesplitter 70 and theONT 60. -
FIGS. 2-11 show an examplefiber distribution terminal 100 that is one example of a configuration for thefiber distribution terminals 30 ofFIG. 1A . Thefiber distribution terminal 100 includes ahousing 101 having a base 102 and afront cover 104. Thefront cover 104 is movable (e.g., pivotally moveable) relative to the base 102 between an open position and a closed position (seeFIG. 2 ). In certain implementations, thefront cover 104 is removable from thebase 102. Thefiber distribution terminal 100 also includes arotatable arrangement 106 positioned withinhousing 101. Therotatable arrangement 106 can rotate relative to thehousing 101 about an axis of rotation 108 (FIG. 4 ). Therotatable arrangement 106 can be rotatably mounted on aspindle 109 coupled to thebase 102 and aligned along the axis of rotation 108 (SeeFIG. 5 ). - Referring to
FIGS. 3-5 , therotatable arrangement 106 includes aspool 110 and amanagement tray 120 that rotate unitarily with each other. Thespool 110 includes adrum portion 112 about which thefiber optic cable 40 is coiled. Thespool 110 also includes aflange 114 that retains thecable 40 on thespool 110. Thespool 110 includes a second flange spaced from thefirst flange 114 along the axis ofrotation 108. In some implementations, the second flange forms amanagement tray 120 at which thecable 40 is coupled to thepatch cords 50. In one example, thefiber optic cable 40 can include a single optical fiber and can include afirst end 40 a (FIG. 3 ) that is connectorized by a single fiber optical connector (e.g., an SC connector, an LC connector, etc.). Thefirst end 40 a of thefiber optic cable 40 can be routed to thefiber distribution hub 20 for connection to thefeed fiber 22 as described above. - The
fiber management tray 120 includes a base 121 extending generally parallel with theflange 114. Thebase 121 defines anaperture 122 through which asecond end 40 b of thefiber optic cable 40 can be routed to an opposite side of the base 121 from thespool 110. In certain implementations, a bend radius limiter extends rearwardly from the base 121 at theaperture 122 to inhibit excessive bending of thecable 40 when thecable 40 transitions through theaperture 122. The base 121 also defines achannel 123 or other structures for providing fiber bend radius protection for routing thesecond end 40 b of thecable 40 to a holdinglocation 124 on themanagement tray 120. In some implementations, the cablesecond end 40 b is connectorized by a single fiber optical connector (e.g., an SC connector, an LC connector, etc.). In such implementations, anadapter 125 can be disposed at the holdinglocation 124 and theconnectorized end 40 b can be inserted into one port of the adapter 125 (seeFIG. 3 ). - To deploy the
fiber distribution terminal 100, the terminal 100 is positioned at the desiredfloor 12 b-12 d and thefiber optic cable 40 is paid off from thespool 110 by pulling on thefirst end 40 a of thefiber optic cable 40. Thefirst end 40 a of thefiber optic cable 40 is pulled down the riser 14 to thefiber distribution hub 20. As thefiber optic cable 40 is paid off from thespool 110, therotatable arrangement 106 rotates relative to thehousing 101 about the axis ofrotation 108 defined by thespindle 109. Themanagement tray 120, theadapter 125, and thesecond end 40 b of thecable 40 are carried with therotatable arrangement 106 and rotate in unison with (i.e., in concert with) therotatable arrangement 106 about the axis ofrotation 108 as thefiber optic cable 40 is paid off from the rotatable arrangement 106 (seeFIG. 6 ). - After the
cable 40 has been connected to thefiber distribution hub 20, thesecond end 40 b of thecable 40 remains at theadapter 125 awaiting a subscriber on therelevant floor 12 b-12 d to request service. In certain implementations, therotatable arrangement 106 can be rotationally locked in position when the cable is dispensed. Upon a request for service, anoptical splitter 70 can be installed on the management tray 120 (seeFIG. 7 ). Theoptical splitter 70 includes a body/housing 71 having at least oneinput region 72 and at least oneoutput region 74. Theoptical splitter body 71 also defines aconnection interface 75 that mounts thesplitter body 71 to thebase 121 of thetray 120. For example, theconnection interface 75 may couple to a mounting interface 126 (e.g., latches, snaps, dove tail, etc.) on the tray 120 (seeFIG. 5 ). In certain implementations, the terminal 100 includes surrounding structure that holds thesplitter body 71 in position. -
FIGS. 8 and 9 illustrate example implementations ofoptical splitters optical splitters 70 ofFIG. 7 . Each of theoptical splitters optical splitters hub 20, or other enclosure. In the example shown, the input port of theoptical splitter splitter optical splitters - As shown in
FIG. 8 , the exampleoptical splitter module 130 has a splitter body/housing 131 defining aninput region 132 and anoutput region 134. In the example shown, theinput region 132 includes an adapter defining an empty port at which theconnectorized end 40 a of thecable 40 can be received. For example, theconnectorized end 40 a can be stored at a fixed location within thedistribution terminal 100 so that mounting thesplitter 130 to the terminal 100 causes theconnectorized end 40 a to enter the adapter. The opposite end of the adapter receives a connectorized end of an internal fiber leading to an optical splitter within thehousing 131. In other implementations, theinput region 132 may include the connectorized end of an internal fiber leading to the optical splitter within the housing 131 (seeFIG. 9 ). In the example shown, theoutput region 134 includes multipleadapter output ports 135 at which first ends 50 a of thepatch cords 50 can be received. In the example shown, theoutput region 134 includes fouradapter output ports 135. - As shown in
FIG. 9 , the exampleoptical splitter module 140 has a splitter body/housing 141 defining aninput region 142 and anoutput region 144. In the example shown, theinput region 142 includes aconnectorized end 143 of an internal fiber leading to an optical splitter within thehousing 141. Theconnectorized end 143 is configured to be received at theadapter 125 when thesplitter module 140 is installed at the tray 120 (seeFIG. 10 ). In other implementations, theinput region 142 may include an adapter defining an empty outward-facing port, such as that shown inFIG. 8 . In the example shown, theoutput region 144 includesmultiple adapter ports 145 at which first ends 50 a of thepatch cords 50 can be received. In the example shown, theoutput region 144 includes eightadapter output ports 145. - In some implementations, the
splitter body 131 of thesplitter module 130 has the same dimensions as thesplitter body 141 of thesplitter module 140. In certain implementations, theoutput region 134 of thesplitter module 130 has the same dimensions as theoutput region 144 of the splitter module 140 (e.g., compareFIGS. 8 and 9 ). In some such implementations, the adapter ports of theoutput region 134 accommodating fewer output paths are more spaced apart than the adapter ports of theoutput region 144 accommodating more output paths. In some such implementations, the adapter ports of theoutput region 134 accommodating fewer output paths can include SC-type adapters and the adapter ports of theoutput region 144 accommodating more output paths can include LC-type adapters, LX.5-type adapters, or other such high density adapters. - Installing the
optical splitter modules adapters splitters fiber distribution terminals 100 before service is requested. In addition, theoptical splitter modules fiber distribution hub 20 as theoptical splitters 26. For example, theoptical splitters fiber distribution terminals 100 can be interchangeable with thesplitters 26 at thefiber distribution hub 20. - As shown in
FIG. 11 , thepatch cords 50 can be used to connect the ONT's 60 to thefiber distribution terminal 100. For example, the first ends 50 a of thepatch cords 50 can be inserted into theoutput ports splitter module patch cords 50 can be routed onto thetray 120 through ports 127 (seeFIG. 5 ). A gasket or other sealing member can be provided at theports 127 to weather-proof the interior of thefiber distribution terminal 100. After deployment of thefiber distribution terminal 100, any remaining unused length of thefiber optic cable 40 can remain coiled on the drum portion of therotatable arrangement 106 for storage within thehousing 101 of thefiber distribution terminal 100. -
FIGS. 12-15 illustrate an alternative type of fiber distribution terminal 200 for use in a fiber distribution system in which a single cable orcable assembly 90 is routed from thehub 20 to the terminals 200 on eachfloor 12 b-12 d. The example terminal 200 does not include a rotatable cable storage spool. - Rather, the terminal 200 includes a base 202 defining a
channel 203 through which thecable assembly 90 can be routed. Thechannel 203 defines abreakout region 201 at which an optical fiber of thecable assembly 90 can be accessed and pulled into thebase 202. Thebreakout region 201 leads to arouting passage 206 that provides slack storage around a spool orbend radius limiter 207. Asplicing passage 208 leads from therouting passage 206 to one or moreoptical splice holders 209. Apigtail passage 205 also connects to therouting passage 206 and/or to thesplicing passage 208. Thepigtail passage 205 extends to a holdinglocation 224 that is configured to hold an optical adapter 225 (FIG. 13 ). - As shown in
FIG. 13 , thecable assembly 90, which is routed through theMDU 12 along a riser or other ducting, is disposed within thebase channel 203. Anoptical adapter 225 is mounted to the holdinglocation 224. Aconnectorized end 94 of asplice pigtail 92 is plugged into one port of theoptical adapter 225. The remaining length of thesplice pigtail 92 is routed through thepigtail passage 205 to thesplicing passage 208. In certain implementations, excess length of thesplice pigtail 92 can be stored in therouting passage 206 before the unconnectorized end of thesplice pigtail 92 is routed to thesplicing passage 208. An optical fiber can be broken out from thecable assembly 90, routed through thebreakout region 201, along therouting passage 206, to thesplicing passage 208. The optical fiber of thecable assembly 90 can be spliced (e.g., mechanical splice, fusion splice, etc.) to thesplice pigtail 92 and stored at one of thesplice holders 209. Thereby, optical signals are carried from thehub 20, along the fiber of thecable assembly 90, along thesplice pigtail 92, to the second port of theoptical adapter 225. - As shown in
FIG. 14 , anoptical splitter 70 can be mounted to thebase 202 of the terminal 200. Any of theoptical splitters base 202. The input connector 73 of thesplitter 70 plugs into the second port of theadapter 225 to receive the optical signals from thehub 20. One ormore patch cords 50 can be plugged into the output ports at thesplitter output region 74 to carry the split optical signals to theONTs 60. As shown inFIG. 15 , acover 204 can be mounted to the base 202 before and/or after thesplitter 70 is mounted to the terminal 200. Thecover 204 provides protection to thesplitter 70, fibers, and connections contained within the terminal 200. - Referring now to
FIGS. 16-29 , afiber distribution hub 300 is shown having anenclosure 302 and adoor 304, which hingedly mounts toenclosure 302. Afiber feed 22 entersfiber distribution hub 300 for connection tooptical splitters 306. Outputs from theoptical splitters 306 are shown asfiber optic cables 40, which route to one or more fiber distribution devices that are installed at different locations within a building. For example,fiber distribution hub 300 can be located in a basement. Fibers fromfiber feed 22 can be spliced atsplice tray 308 tosplitter inputs 310, which lead to eachsplitter tray 312. Eachsplitter tray 312 holds one ormore splitters 306 with a mounting device like the type noted above forterminals 100, 200.Splitters 306 in the example include oneinput 328 and eightoutputs 330.Splitters 306 are constructed in a similar manner as previously describedoptical splitters Splitter 306 is interchangeable withsplitters -
Splice tray 308 andsplitter trays 312 are mounted to abacking plate 316.Splitter trays 312 are pivotally mounted so as to permit access to a desired splitter tray in the stack ofsplitter trays 312. The pivotingsplitter trays 312 can also allow access to splicetray 308 as desired. Eachsplitter tray 312 holds twooptical splitters 306 and therespective splitter inputs 328. - As shown, each
splitter tray 312 includes cable routing for routing of thesplitter inputs 328, which are outputs from the splice tray in one example. Therouting pathways 320 extend around a perimeter ofsplitter tray 312.Cable routing 320 can includecable management troughs 322,fingers 324 and rings 326.Splice tray 308 includes afiber input 332 and a fiber output 334.Splice tray 308 opens up and allows internal storage of the fiber splice. -
Fiber distribution hubs feed fiber 22. In some cases,feed fiber 22 can be split out to multiple hubs so as to distribute the splitting and splicing functions amongmultiple hubs splitters -
FIG. 30 illustrates anotherfiber distribution hub 400 similar to thehub 300 illustrated inFIGS. 16-29 . Thefiber distribution hub 400 includes anenclosure 402 and is shown without a cover to illustrate the internal features thereof In thefiber distribution hub 400, theoptical splitters 406 are oriented in a horizontally stacked arrangement adjacent thebottom 401 of theenclosure 402. Theoptical splitters 406 are arranged in a direction from afront 403 of thehub 400 toward a back 405 of thehub 400. As in thehub 300 ofFIGS. 16-29 , theoptical splitters 406 are configured to receive an input signal from afiber feed 22 that entersfiber distribution hub 400. In the example of thehub 400, fiber feeds 22 enter fromsides enclosure 402 and fibers from thefiber feed 22 are spliced tosplitter inputs 410 at asplice region 408 within theenclosure 402. Outputs from theoptical splitters 406 are shown asfiber optic cables 40, which exit the enclosure from a top 411 and route to one or more fiber distribution devices that are installed at different locations within a building. For example, as inhub 300,hub 400 can be located in a basement. Each of thesplitters 406 may be mounted to theenclosure 402 with a mounting device like the type noted above forterminals Splitters 406 in the example include oneinput 410 and eightoutputs 430.Splitters 406 are constructed in a similar manner as previously describedoptical splitters Splitter 406 is interchangeable withsplitters - Referring now to
FIGS. 31-37 , anotherfiber distribution hub 500 similar to thehub 400 illustrated inFIG. 30 is shown. Thefiber distribution hub 500 includes anenclosure 502 for housingfiber optic splitters 506 in a manner similar to the arrangement shown inFIG. 30 . InFIG. 32 , theenclosure 502 is shown without acover 504 to illustrate thesplitters 506 located within theenclosure 502. In thefiber distribution hub 500, in addition to thesplitters 506, a plurality offanouts 580 are located above theenclosure 502. Thefanouts 580 are oriented in a stacked arrangement similar to thesplitters 506 therebelow in a direction from thefront 503 of thehub 500 toward the back 505 of thehub 500. As in thehub 400 ofFIG. 30 ,fiber feed 22 entersfiber distribution hub 500 for connection to theoptical splitters 506. Similar to thehub 400 ofFIG. 30 , thefiber feed 22 enters from thesides enclosure 502 and fibers from thefiber feed 22 are spliced tosplitter inputs 510 at asplice region 508 within theenclosure 502. However, in contrast to the arrangement shown inFIG. 30 , theriser cables 40 are spliced into pigtails at thefanouts 580 located above theenclosure 502. The connectorized pigtails then lead to theoutputs 530 of thesplitters 506. In this manner, theriser cables 40 do not have to be preterminated with connectors, which can often lead to issues in providing the correct length for the individual cables. - The
fanouts 580 are shown in isolation inFIGS. 33 and 34 . Eachfanout 580 includes ariser cable port 582 at a top 581 of thefanout 580 and apigtail port 584 at a bottom 583 of thefanout 580. Asplice region 585 is provided within thefanout 580 as well as acable management spool 587 for managing fibers within thefanout 580 without violating minimum bend radius requirements. - The
splitters 506 are shown in isolation inFIGS. 35-37 . Thesplitter 506 is shown inFIG. 37 without a cover 511 thereof for illustrating the internal structure thereof. In the depicted example of thehub 500, thesplitters 506 are 1×16 splitters. As in the earlier described embodiments, eachsplitter 506 may be mounted to theenclosure 502 with a mounting device like the type noted above.Splitters 506 are constructed in a similar manner as previously describedoptical splitters Splitter 506 is interchangeable withsplitters - Referring now to
FIGS. 38-55 , anotherfiber distribution hub 600 is shown. The fiber distribution hub includes anenclosure 602 including abasepart 604 and acover 606. In the illustrated embodiment, cables enter and exit from the sides ofhub 600.Basepart 606 includes a firstmajor side 650, a secondmajor side 652 generally parallel to firstmajor side 650, a firstminor side 654, and a secondminor side 656 oppositely disposed to firstminor side 654.

Aconnector 712 extends fromsplice 710 and mates withadapter 714.Output connector 715 with cable connects toconnector 712 to provide service to a single customer or outlet. - If additional customers or outlets are in need of service, a
splitter 716 can be used instead ofoutput connector 715.Splitter 716 includes a plurality ofoutputs 718 each with anoutput adapter 717 matable to anoutput connector 715 with cable. - A
splitter input connector 720′ is illustrated in the modified version offiber distribution terminal 700′ shown inFIGS. 62-69 . Similar parts are noted with an apostrophe inFIGS. 62-69 relative toFIGS. 56-61 . Thesplitter input connector 720 is on the rear ofsplitter 716 and not visible inFIGS. 56-61 .Splitter 716 mounts with a sliding motion in the illustrated examples.Splitter 716 can be easily added after installation ofterminal 700, when single service is no longer needed, and additional outputs are desired for servicing multiple customers or multiple units/outlets. - The
splitter 716′ ofFIGS. 62-69 includes abase 740, afront cover 742, and anintermediate tray 744.Tray 744 holdsoutput connector 720′ andoutput adapters 717′. - Various features of
splitters - The splitter output and splitter input are in the opposite direction in one implementation.
- The input-adapter is placed in the base (not in splitter) to be able to add a single customer pigtail, if desired.
- The splitter output is facing downwards, and the splitter-input is upwards in one implementation.
- The pigtail for a single customer (in case of no splitter) is leaving the box at the bottom (same exit-direction as for pigtail exit in case of a splitter) in one implementation.
- The splitter output adapters are placed generally in the center of the splitter module, in one implementation
- The splitter input connector is placed generally in the middle of the module but in a different height level; underneath the splitter out adapters in one implementation.
- The output adapters of the splitter are placed vertically to keep the width small in one implementation.
- The input connector is placed horizontally to keep height small in one implementation.
- The pigtail boots clicked in the splitter out adapter (splitter out) are within the splitter footprint in one implementation.
- The splitter has side bend-protection for the pigtail attached in the splitter adapter out ports in one implementation.
- In one implementation, the width of the splitter is around 90 mm, the length is around 120 mm.
- The adapters can be provided at a slight angle for extra access by the user in one implementation.
- A sealing foam strip can be added to the splitter to close the pigtail opening between splitter and outer cover which can be added over the splitter like
cover 704 in one implementation. - A fixating screw can be added to fix the splitter to the base; with the screw direction is aligned with the feeder-adapter mating direction in one implementation.
- Referring now to
FIGS. 70 and 71 ,splitter 816 includesinputs 818 in the form of adapters, andsplitter outputs 820 in the form of adapters.Splitter 816 also includes one or moreconnector storage locations 840. Twolocations 840 are shown forsplitter 816. Eachlocation 840 can store aconnector 842 for later use as an output connector foroutputs 820. Such a situation can occur if the connector or cable in one ofoutputs 820 becomes damaged.Connector 842 can be used to change out the damaged connector/cable and provide a ready to use back up signal path.Location 840 stores an end ofconnector 842 in a protective manner and also keeps it organized for a future deployment.Connector 842 is an extra pigtail of the riser cable in one example. - In one implementation,
location 840 is located close to the central channel of the hub. - With the above systems, splitters can be mounted in a hub and/or in an MDU or floor box as desired. Various of the systems provide flexibility for adding splitters as needed after initial installation of the system. Various of the systems utilize splicing for adding pigtails to cables which are not preconnectorized. However, the above systems can be used with preconnectorized cables, in the case of feeder, riser, or other.
- Various modifications and alterations of this disclosure will become apparent to those skilled in the art without departing from the scope and spirit of this disclosure, and it should be understood that the scope of this disclosure is not to be unduly limited to the illustrative examples set forth herein.
