Fiber optic cable management system
First Claim
1. A fiber optic cable management system for connecting to optical fibers, comprising:
- an enclosure having enclosure side walls;
a tray slidingly insertable into the enclosure and slidingly extendable at least partially out from the enclosure, the tray including;
a floor and side walls;
sliders attached to an inside surface of the enclosure side walls; and
mating sliders attached to an outside of the side walls of the tray, wherein the sliders slidingly reciprocate in brackets attached to the inside surface of the enclosure side walls, and the mating sliders slidingly reciprocate within the sliders;
one or more optical fiber modules located inside the tray and including front optical fiber ports extending out front ends of the fiber modules, back optical fiber ports extending out back ends of the fiber modules, and rails located on opposite sides of the optical fiber modules slidingly coupling the optical fiber modules to the side walls of the tray, wherein the optical fiber modules can slide independently of the floor and side walls of the tray when the tray is extended at least partially out of the enclosure moving the back ends of the modules out of the enclosure and locating the back optical fiber ports a spaced distance in front of a front end of the enclosure; and
optical fiber splitters located inside ones of the fiber modules, the optical fiber splitters each connected between a first one of the optical fiber ports configured to connect to a remote radio unit, and a second one of the optical fiber ports configured to connect to a baseband unit (BBU).

Abstract
A fiber optic cable management system includes a tray configured to reciprocate inside of an enclosure between an inserted position and an extended position. Optical fiber modules are located in the tray and retain optical fiber splitters or optical fiber multiplexer/de-multiplexers. The tray when moved to the extended position moves the optical fiber modules out of the front end of the rack enclosure. This allows a technician to access the back of the modules for maintenance operations without having to access the back end of the enclosure. A flexible cable guide allows the optical fibers connected to the modules to move with the tray into and out of the enclosure. Reflectors can be attached to the connectors to test fiber optic lines between a central office and the cell site location.
