Abstract

A fiber distribution frame includes a fixture having a plurality of modules mounted side-by-side within said fixture with each of the modules being individually mounted in a line of travel. Each of the modules can be locked in any one of a plurality of discrete positions within the line of travel. Each of the modules contains a plurality of adapters for receiving and retaining fiber optic connectors. Further, the fixture may be tilted downwardly to provide access to the rear of the fixture.

Claims

1. A fiber optic distribution frame comprising:

a frame member including a base with said frame member having means for supporting a plurality of assemblies along a vertical length of said frame member;

p1 a plurality of connector assemblies secured to said frame with each of said assemblies including a plurality of modules, said modules mounted for individual movement along individual ones of a plurality of lines of travel with each one of said modules including a plurality of adapters for holding a fiber optic connector, each one of said adapters moveable with said one of said modules along a respective line of travel of said one of said modules, said adapters dispersed in a side-by-side array having a longitudinal axis parallel to said lines of travel;

each of said fiber optic connectors having means for connecting a first signal transmission cable at a rear side of said adapter with a second signal transmission cable connected at a front side of said adapter;

a fiber guide secured to said frame for organizing fibers directed toward said modules.

2. A high density fiber distribution frame according to claim 1 wherein said modules mounted in side-by-side relation with said longitudinal axes generally parallel to said lines of travel.

3. A high density fiber distribution frame according to claim 2 wherein said longitudinal axis is vertically oriented.

4. A high density fiber distribution frame according to claim 1 wherein said modules are split for said plurality of adapters to include a first set and a second set of adapters each separately movable along said respective line of travel.
