DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring now to FIGS. 1 and 3, a fiber distribution apparatus 10 is shown for use in cross-connect applications. FIGS. 2 and 4 show a similar fiber distribution apparatus 10′ configured for interconnect applications. Both apparatus 10, 10′ include an outer enclosure 20, and an inner frame 22 including a plurality of optical modules 23 mounted thereto. As will be described below in greater detail, modules 23 have particular functions, and apparatus 10, 10′ is preferably provided with different modules 23 selected to have the desired functions for the particular application.

Enclosure 20 typically extends from the ground over underground cables 300, 302 (FIG. 3) and 400, 402 (FIG. 4) which extend upwardly from the ground and contain multiple individual optical fibers or bundles of fibers. Cables 300, 302, 400, 402 may be single cables or multiple cables. Enclosure 20 protects the inner components, in this case fiber optic telecommunications equipment. Enclosure 20 can be any convenient structure sized to protect frame 22 and modules 23. In the drawings, enclosure 20 includes a main vertical portion 40 extending from the ground and a top cap 42. Typically, a movable front door is provided, and a lock provides secure access.

Referring now to FIGS. 1-7, frame 22 is secured to main portion 40 of enclosure 20 along a rear side 41 of main portion 40. Frame 22 includes a base or bottom 50, and an opposed top 52. Frame 22 further includes a front 54, and an opposed rear 56, and spaced apart sides 58. Rear 56 of frame 22 can be screwed, riveted, or otherwise fastened to rear side 41 of main portion 40 of enclosure 20 through holes 62.

Frame 22 further includes an upper module mounting bracket 66, and a lower module mounting bracket 68 extending between sides 58. Each module mounting bracket 66, 68 receives a plurality of modules 23 connected via fasteners 70, such as screws, or other fasteners. Preferably, the fasteners are releasable to enable removal of modules 23, as desired, such as for repair, or replacement. Each of the module mounting brackets 66, 68 includes a plurality of holes 67, 69 for receipt of fasteners 70.

Lower module mounting bracket 68 defines a cable tray 60 (FIG. 5) including a plurality of lower holes 72, each sized for receipt of one or more cables, as will be described in greater detail below.

A cover 76 (FIGS. 5 and 6) mounts to frame 22 so as to close front 74. Side flanges 78 to cover 76 include a plurality of downwardly angled slots 80 for receipt of pins 82 extending from sides 58, 60 of frame 22. Nuts, such as wing nuts, can be mounted to pins 82 with threads to help secure cover 76 to frame 22.

Referring now to FIGS. 1-4, and 8-12, a connection module 24 is shown. Connection module 24 comprises one of modules 23. Connection module 24 includes a front 90 defining a plurality of connection locations 91. Front 90 also includes opposed mounting flanges 92, 94 extending along front 90 for mounting to module mounting brackets 66, 68 of frame 22. Each of flanges 92, 94 includes a plurality of holes 96, 98 for receiving fasteners 70. A spaced apart rear 100 of connection module 24, and a spaced apart top 102 and bottom 104, and opposed, spaced apart sides 106, 108 define an interior region. A cable notch 110 formed by portion of rear 100, bottom 104, and sides 106, 108 receives a cable 300 for connection to the connection locations 91 within the interior of module 24. Notch 110 further includes an opening 112 for cable 300. Opening 112 is large enough to receive one or more additional cables.

Each of the connection locations, 91 preferably includes an adapter 200 for mounting to a fiber optic connector, such as an SC (shown), an ST, an FC, or other connector. Cable 300 entering connector module 24 at opening 112 includes its individual fibers connected to the individual connection locations 91, as desired. Two illustrated example fibers 300a, 300b of cable 300 connect to two connection locations 91. A connector 208 (FIG. 11) is preferably on an end of fibers 300a, 300b. Adapter 200 preferably has two ends 202 and 204. End 202 is disposed within module 24 for connection to connector 208. Opposite end 204 defines the exposed opening of the connection location 91 along the front of module 24 for connection to a second connector 218. A clip 210, such as the clip disclosed in U.S. Pat. No. 5,214,735 may be used to releasably attach each adapter to module 24. Clip 210 also angles connection locations 91 downwardly when module 24 is installed in frame 22 as in the drawings. Each clip 210 holds each adapter 200 in one of the openings 93 of front 90 of module 24 to define each connection location in the preferred embodiment. In the illustrated embodiment of module 24, only two connection locations 91 are shown, but a fully loaded module 24 would define a connection location 91 at each opening 93. Clip 210 is preferably a snap mounted clip to enable easy assembly. A removable clip 210 is preferred to allow cleaning of connector 208 and end 202 if desired.

A similarly configured second connection module 24a is mounted to frame 22 to permit cross-connection through the use of patch cords 114a, 114b (FIG. 3) to cross-connect between the fibers of each cable connected to the respective connection modules 24, 24a. Cable 302 is connected to the rear of module 24a as cable 300 is for module 24. Patch cords 114a, 114b, and fibers 300a, 300b are shown schematically in FIGS. 3 and 9, but each fiber has a connector like connectors 208, 218 to mate with adapter 200. Alternatively, other connector systems as noted above can be used, as desired.

Each connection module 24, 24a can be made of sheet metal sections, held together with fasteners, such as screws, so as to allow access as desired to the interior of each module.

To facilitate cable management, and cable protection, a cross-connect storage module 26 as one of modules 23 is provided having three spools 116 along a front 120 (FIGS. 1, 3 and 20). Along a front 120 of an interconnect storage module 26a as one of modules 23 is provided two spools 116 (FIGS. 2, 4 and 21). Flanges 124, 126 permit mounting of each storage module 26, 26a to frame 22 in a similar manner as modules 24, 24a. Holes 128, 130 receive fasteners 70 to mount storage modules 26, 26a to frame 22. Front projections 118 along vertical side edges 117 further enable cable management and cable protection during use. A cable clamp 134 (FIG. 4) is provided for front mounting of one or more cables to storage module 26a for the interconnect system. Posts 135 (FIG. 21) hold the clamp pieces.

Cable notch 110 is useful to avoid excess cable bending during manipulation and positioning of connection modules 24. The use of notch 110 provides a greater distance between the cables extending upward from the ground to the clamp mounting locations on modules 24. The extra distance is advantageous when manipulating module 24 as it is installed into or removed from frame 22.

In the example cross-connect system of FIG. 3, two fibers 300a, 300b (FIG. 9) of cable 300 are shown as optically linked to two fibers of cable 302 through patch cords 114a, 114b in a cross-connect application between modules 24, 24a. In the example interconnect system of FIG. 4, two fibers 402a, 402b of cable 400 are shown as optically linked to two fibers of cable 400.

Referring now to FIGS. 18 and 19, alternative connection modules 224, 226 include different numbers of vertical rows of connector locations 91. Modules 24, 24a included two vertical rows. Connection module 224 includes a single row of connection locations 91, and connection module 226 includes three. Four or more rows are also possible.

Referring now to FIGS. 13-17, module 24 is shown as including optical components such as splices and/or optical couplers within the module between cable 300, and connection locations 91. In FIGS. 13 and 14, a splice 350 to a one-by-two optical splitter 351 allows for module 24 to have line and monitor functions associated with connection locations 91. Row 352 of connection locations 91 could serve as the line function, and row 354 could serve as the monitor function. Each pair of connection locations 91 (one from each row) would be linked to one of the fibers of cable 300 in FIG. 13. Other splitters, such as one-by-fours, etc. may be used, as desired.

In FIGS. 15 and 16, a splice 360 to a wave division multiplexer (WDM) 361 allows for module 24 to have wavelength division multiplexing functions associated with connection locations 91. A “dense” wave division multiplexer may be used, if desired (DWDM). For the multiplexing function, row 362 of connection locations 91 could serve as the first wavelength ports, and row 364 could serve as the different wavelength ports. Each pair of connection locations 91 (one from each row) would be linked to one of the fibers of cable 300 in FIG. 15.

FIG. 17 shows just a splicing component 370 so that each fiber of cable 300 could be spliced to a fiber leading to one connection location 91. Other passive optical components can be selected as desired to provide module 24 with the desired function or functions.

Referring now to FIGS. 22 and 23, blank panels 150, 170 comprising modules 23 are shown. Each blank panel 150, 170 includes a generally planar front 152, and flanges 154 including holes 158, 160 to enable mounting of the blank modules 150, 170 to frame 22. Blank modules 150, 170 are utilized to fill open spaces of frame 22. Blank module 170 is a single width, and blank module 150 is a double width. Additional widths can be supplied as desired.

During assembly of a system for a particular outside plant application, the desired function (cross-connect, interconnect, other) is selected. The types of modules 23 (connection, storage, blank) and widths of modules 23 are also selected. Further the types of connections and whether any optical splices or optical couplers are to be utilized are selected. The appropriate modules are selected and then mounted to frame 22 within an enclosure 20. Over time, the modules 23 can be removed for repair, replacement, or to change function. Also, the front connections can be changed as the need arises.

The above specification, examples and data provide a complete description of the manufacture and use of the composition of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
