Abstract

A high density fiber enclosure system includes a chassis, cassette trays, an optional unification clip, cassettes, and an optional trunk cable management system. The chassis, cassette trays, and cassettes are configured such that individual cassettes may be installed, removed, and otherwise positioned for easy access by a user. The unification clip allows two adjacent cassette trays to be connected to one other such that cassette trays move as one unit. The trunk cable management system is designed to organize trunk cables and trunk cable furcation legs as well as relieve strain on the trunk cables and trunk cable furcation legs.

Claims

1. A method for loading a cassette into a high density enclosure, comprising:

advancing a cassette tray to a cassette installation position inside a chassis;

inserting a cassette into a cassette bay formed between two rails disposed on said cassette tray by placing a rear portion of said cassette on the tray so that said rear portion of said cassette is located between a front post stop area and rear post stop on each of said rails, wherein said rails include front patch cord management loops disposed on a front portion of said rails;

tilting said cassette slightly upward so that a front portion of said cassette is higher than said rear portion of said cassette, wherein said tilting said cassette slightly upward comprises tilting said front portion of said cassette upward until said front portion of said cassette is disposed above said front patch cord management loops;

pushing said cassette backward into said cassette bay while maintaining said tilt of said cassette until rear posts of said cassette engage with said rear post stops on said rails; and

applying downward pressure on said front portion of said cassette until front posts of said cassette are secured in said front post stop area.

2. The method of claim 1 further comprising connecting patch cords to said cassette.

3. The method of claim 1 further comprising connecting trunk cables to said cassette prior to pushing said cassette backward into said cassette bay.

4. The method of claim 1 further comprising said cassette having local connector adapters (“

LC adapters”

).

5. The method of claim 1 further comprising said cassette having multi-fiber push-on/pull-off adapters (“

MPO adapters”

).

6. The method of claim 1 wherein advancing said cassette tray to said cassette installation position further comprising advancing said cassette tray until a spring protrusion disposed on the outside of one of the rails engages with a detent located on said chassis.
