Abstract

Abstract An oprical fiber cable closure (20) includes a cable termination assembly (22) and a cover (23) into which the termination assembly is inserted. The cable termination assembly includes two spaced end plates (34,36) through which cables (28,29) to be spliced extend. One of the end plates supports a frame (101) which supports a plurality of optical fiber splicing trays (120-120). Adjacent end portions of the trays are staggered and hinged so that some trays may be moved pivotally to expose others. Optical fibers from each incoming cable are routed in individual tubes (115-115) or as ribbons from an optical fiber breakout (110) mounted in the frame to selected ones of the trays. Hinge lock plates (130-130) which complete a hinge for each tray also serve to clamp the tubes incoming to each tray to prevent unintended movement. Each of the trays may be provided with a plurality of organizing modules (140,140) each of which is adapted to hold a plurality of optical fiber connective devices. Advantageously, each of the modules includes a compliant insert (160) which not only holds a plurality of splicing connections but also is capable of storing any of a plurality of commercially available connective arrangements. The modules have utility in environments other than in closures.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 156 words
An optical fiber cable closure, said closure comprising: a cover having a closed end and an open end; and a cable termination assembly which is adapted to become disposed within said cover, said cable termination assembly including: cable entry means through which cables to be provided with connective arrangements are routed into said closure; support means which extends from said cable entry means and which has a free end adapted to be disposed adjacent to said closed end of said cover, and at least one tray which is mounted on said support means for holding optically connected portions of optical fibers of cables; said closure being characterized by at least one organizing module which is mounted in said at least one tray, each said module including compliant means for holding a plurality of optical fiber connective arrangements which may include different kinds of connective arrangements, said tray being capable of holding a plurality of said modules.
Claim 2
Dependent Claim 41 words
The closure of claim 1, wherein each said organizing module includes a holder, and an insert which is adapted to become supported in said holder, said insert being made of a compliant material and having a plurality of nests formed therein.
Claim 3
Dependent Claim 103 words
The closure of claim 2 wherein said insert is formed to include a plurality of parallel, longitudinally extending nexts therein, each said nest at each end of said insert communicating with a groove which opens to an outer surface of said insert and with a bore which opens to an end face of said insert, wherein each said insert includes opposed sidewalls and a plurality of partitions between which are formed said nests, each of said sidewalls and each of said partitions being provided with a slot with the slots in the sidewalls and in the partitions being aligned transversely across said insert.
Claim 4
Dependent Claim 69 words
The closure of claim 3, wherein said holder is provided with a surface which engages a surface of said insert and to which a plurality of longitudinally extending slots open, said slots being aligned with said nests in said insert when said insert is supported in said holder, and wherein an opposite surface of said holder is provided with an adhesive material to secure said holder to a surface.
Claim 5
Dependent Claim 43 words
The closure of claim 3, wherein said holder is provided with tabs along said sidewalls thereof such that when two such inserts become disposed adjacent to each other, said tabs of adjacent sidewalls become interleaved to form a channel for receiving optical fiber.
Claim 6
Dependent Claim 22 words
The closure of claim 2, wherein each said insert is capable of being separated from a holder in which it is mounted.
Claim 7
Dependent Claim 84 words
An organizing module for holding at least one optical fiber connective arrangement, said organizing module comprising: a holder, an insert which is supported in said holder and which includes a plurality of nests each adapted to receive an optical fiber connective arrangement, said insert being made of a material and having a configuration which facilitates the reception and the retention of any of a plurality of optical connective arrangements in each of said nests; and means for attaching said holder to a supporting surface.
Claim 8
Dependent Claim 54 words
The organizing module of claim 7, wherein said insert is formed to include a plurality of parallel nests therein, each said nest at each end of said insert communicating with a groove which opens to an outer surface of said insert and with a bore which opens to an end face of said insert.
Claim 9
Dependent Claim 54 words
The organizing module of claim 8, wherein each said insert includes opposed sidewalls and a plurality of partitions between which are formed said nests, each of said sidewalls and each of said partitions being provided with a slot with the slots in the sidewalls and in the partitions being aligned transversely across said insert.
Claim 10
Dependent Claim 49 words
The organizing module of claim 9, wherein said holder is provided with a surface which engages a surface of said insert and to which a plurality of longitudinally extending slots open, said slots being aligned with said nests in said insert when said insert is supported in said holder.
