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 removing a cassette installed in a high density enclosure, comprising:

advancing a cassette tray to a cassette removal position;

applying upward pressure on a front portion of said cassette near front posts of said cassette until front posts of said cassette are released from a front post stop area on rails disposed on said cassette tray while rear posts on said cassette remain engaged with rear post stops on said rails;

tilting said cassette slightly so that said front portion of said cassette is higher than said rails;

pulling said cassette away from a front side of said cassette tray while maintaining said tilt of said cassette until rear posts on said cassette clear said front side of said cassette tray; and

removing said cassette from said cassette tray.

2. The method of claim 1 further comprising removing patch cords from said cassette prior to pulling said cassette away from said front side of said cassette tray.

3. The method of claim 1 further comprising removing trunk cables from said cassette prior to removing said cassette from said cassette tray.

4. The method of claim 1 further comprising said cassette having LC adapters.

5. The method of claim 1 further comprising said cassette having MPO adapters.

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

7. The method of claim 1 further comprising said rails including front patch cord management loops disposed on a front portion of said rails.

8. The method of claim 7 wherein said tilting said cassette slightly upward further 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.

13. The method of claim 1 further including sliding said rear posts on said cassette within a channel of said rails when pulling said cassette away from the front side of said cassette tray.

9. A method for removing a cassette installed in a high density enclosure, comprising:

applying upward pressure on a front portion of said cassette until said front portion of said cassette is released from a front post stop area on rails disposed on a cassette tray while a rear portion of said cassette remains engaged with rear post stops on said rails;

tilting said cassette slightly so that said front portion of said cassette is higher than said rails;

pulling said cassette away from a front side of said cassette tray while maintaining said tilt of said cassette until said rear portion on said cassette clears said front side of said cassette tray; and

removing said cassette from said cassette tray.

10. The method of claim 9 further comprising advancing said cassette tray to a cassette removal position until a protrusion disposed on the outside of one of the rails engages with a detent located on a chassis.

11. The method of claim 9 further comprising said rails including front patch cord management loops disposed on a front portion of said rails.

12. The method of claim 11 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.
