Abstract

Optical fiber supporting and routing apparatus is disclosed which includes a support member for attaching a multiplicity of optical fibers which are bundled together and the bundle is coiled. An attaching bracket is secured to the support member for mounting the distribution unit.

Claims

1. An optical fiber distribution unit mounted in a distribution cabinet with a support frame comprising:

a support member;

a multiplicity of optical fibers, each optical fiber having a first end and a terminal end, said multiplicity bundled together and said bundle coiled and attached to said support member;

a bracket secured to said support member for mounting said distribution unit, said bracket defining a hook portion for hooking to a portion of said support frame;

a quick disconnect member cooperating with said bracket for securing said mounted distribution unit to said support frame, said quick disconnect member defining a spring-catch spaced from said hook portion and located to engage another portion of said frame.

13. The apparatus of claim 14 wherein said quick disconnect member defines a spring-catch spaced from said hook portion and located to engage another portion of said frame.

14. The apparatus of claim 1 and further comprising:

a support rail defining a plurality of support notches, said support rail being secured to said frame; and

at least one spool being received and supported by one of said notches such that said spool is positioned and located so as to support at least one of said optical fibers in said bundle as said optical fiber is routed to a termination point.

2. An optical fiber distribution unit for use with a distribution terminal having a support frame comprising:

a support member;

a multiplicity of optical fibers, each optical fiber having a first end and a terminal end, said multiplicity bundled together and said bundled together and said bundle coiled and attached to said support member;

a bracket secured to said support member for mounting said distribution unit;

a support rail defining a plurality of support notches, said support rail being secured to said frame;

at least one spool being received and supported by one of said notches such that said spool is positioned and located so as to support at least one of said optical fibers in said bundle as said optical fiber is routed to a termination point, said spool including a fiber-optical support post and said support post defines a circumferential attaching groove at a first end of said spool, and said support rail has a front face and a side face to form an “

L”

cross-sectional shape, said support notches defined in said front face of said support rail having a throat portion extending from an entrance groove defined in said side face of said rail such that said circumferential groove of said spool passes through said throat portion to said support notch.

3. The apparatus of claim 2 wherein said spool further defines a backing plate attached to said first end of said spool, said backing plate having a larger area than the cross section of said spool and said entrance groove being large enough to receive said backing plate.

4. The apparatus of claim 2 and further comprising a quick disconnect member cooperating with said bracket for securing said mounting distribution unit.

10. The apparatus of claim 2 wherein said optical fiber distribution unit is mounted in a distribution cabinet with a support frame and further comprising a quick disconnect member cooperating with said bracket for securing said mounted distribution unit to said support frame.

11. The apparatus of claim 2 wherein said distribution unit is for use with a distribution terminal having a support frame and said bracket defines a hook portion for hooking to a portion of said support frame for mounting said unit to said frame.

12. The apparatus of claim 11 wherein said optical fiber distribution unit is mounted in a distribution cabinet with a support frame and further comprising a quick disconnect member cooperating with said bracket for securing said mounted distribution unit to said support frame.

5. An optical fiber distribution unit for use with a distribution terminal having a support frame comprising:

a support member;

a multiplicity of optical fibers, each optical fiber having a first end and a terminal end, said multiplicity bundled together and said bundle coiled and attached to said support member;

a support rail defining a plurality of support notches, said support rail being secured to said frame;

at least one spool being received and supported by one of said notches such that said spool is positioned and located so as to support at least one of said optical fibers in said bundle as said optical fiber is routed to a termination point;

a bracket secured to said support member for mounting said distribution unit;

a quick disconnect member cooperating with said bracket for securing said mounted distribution unit;

said bracket defining a hook portion for hooking over a portion of said frame to mount said unit to said frame and said quick-disconnect member is a spring-catch spaced from said hook portion and located to engage another portion of said frame.

6. In a terminal facility having a first panel mounted to a support frame for providing distribution terminals for optical fibers, apparatus for adding a second optical fiber distribution panel, comprising:

a second panel for providing distribution connections for optical fibers; and

an optical fiber distribution unit comprising;

a support member;

a multiplicity of optical fibers, each optical fiber having a first end terminating in said second panel and a terminal end having a connector suitable for connecting to a matching connector on said first panel, said multiplicity of optical fibers bundled together and said bundle coiled and attached to said support member,

an attaching bracket secured to said support member for mounting said distribution unit to said support frame at a location proximate said first panel, said bracket defining a hook portion for hooking over a portion of said frame to mount said unit to said frame and said quick disconnect member is a spring-catch spaced from said back portion and located to engage another portion of said frame.

7. The apparatus of claim 6 and further comprising:

a support rail defining a plurality of support notches, said support rail being secured to said frame; and

at least one spool received and supported by one of said notches such that said spool is positioned and located so as to support at least one of said optical fibers in said bundle as said optical fiber is routed to a termination point.

8. In a terminal facility having a first panel mounted to a support frame for providing distribution terminals for optical fibers, apparatus for adding a second optical fiber distribution panel, comprising:

a second panel for providing distribution connections for optical fibers; and

an optical fiber distribution unit comprising;

a support member;

a multiplicity of optical fibers, each optical fiber having a first end terminating in said second panel and a terminal end having a connector suitable for connecting to a matching connector on said first panel, said multiplicity of optical fibers bundled together and said bundle coiled and attached to said support member,

an attaching bracket secured to said support member for mounting said distribution unit to said support frame at a location proximate said first panel;

a support rail defining a plurality of support notches, said support rail being secured to said frame;

at least one spool received and supported by one of said notches such that said spool is positioned and located so as to support at least one of said optical fibers in said bundle as said optical fiber is routed to a termination point said spool includes a fiber-optic support post and said support post defines a circumferential attaching groove at a first end of said support post, and said support rail has a front face and a side face so as to form an “

L”
