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.

First claim

What is claimed is:

1. A fiber enclosure comprising:
a chassis configured to house a plurality of cassettes;
a first tray guide secured to the chassis, the first tray guide including a plurality of first detents;
a second tray guide secured to the chassis, the second tray guide including a plurality of second detents;
a cassette tray configured to move between the first tray guide and the second tray guide, the cassette tray comprising:
a first rail having a continuous length extending from a rear end and a front end of the first rail, the first rail configured to move within the first tray guide, the first rail including a first stopping member configured to engage with the plurality of first detents included in the first tray guide, the first rail further including a first routing member comprising the front end of the first rail wherein the first routing member is configured to route a cable at a front end of the fiber enclosure;
a second rail configured to move within the second tray guide, the second rail including a second stopping member configured to engage with the plurality of second detents included in the second tray guide;
a tray base; and
a third rail configured to be removably attached to the tray base between the first rail and the second rail.

2. The fiber enclosure of claim 1 , wherein at least one of the first rail or the second rail includes a unification clip slot configured to receive a unification clip.

3. The fiber enclosure of claim 1 , wherein the third rail includes a third routing member configured to route a cable at a front end of the fiber enclosure.

4. The fiber enclosure of claim 1 , wherein the first stopping member and the second stopping member are a flexible metal spring.

5. The fiber enclosure of claim 1 , further comprising:
a slack management plate configured to manage slack in a cable installed into the fiber enclosure, the slack management plate configured to be removably attached to a rear of the chassis by at least one spring-loaded fastener.

6. The fiber enclosure of claim 1 , further comprising:
a slack management plate configured to manage slack in a cable installed into the fiber enclosure, the slack management plate configured to be removably attached to a rear of the chassis and the slack management plate includes at least one fastener configured to removably secure the slack management plate to be substantially level relative to the chassis.

7. The fiber enclosure of claim 1 , further comprising:
a slack management plate;
a divider; and
a plurality of openings on each of a first side and a second side of the divider for removably attaching the divider at different locations on the slack management plate.

8. The fiber enclosure of claim 1 , further comprising:
a slack management plate;
a divider disposed perpendicular to a plane of the slack management plate; and
a plurality of openings on each of a first side and a second side of the divider for removably attaching the divider at different locations on the slack management plate.

9. The fiber enclosure of claim 1 , further comprising a slack management plate, the slack management plate comprising:
a first side wall configured to be rotatably attached to a first side wall of the chassis by a first support pin; and
a second side wall configured to be rotatably attached to a second side wall of the chassis by a second support pin.

10. The fiber enclosure of claim 1 , wherein the plurality of first detents include at least three detents and the plurality of second detents includes at least three detents.

11. The fiber enclosure of claim 1 , further comprising:
at least three layers of the first tray guide stacked on top of each other; and
at least three layers of the second tray guide stacked on top of each other.

12. The fiber enclosure of claim 1 , wherein:
the first rail further comprising a first rear post stop configured to prevent a cassette installed into the cassette tray using the first rail from further moving past the first rear post stop; and
the second rail further comprising a second rear post stop configured to prevent a cassette installed into the cassette tray using the second rail from further moving past the second rear post stop.

13. The fiber enclosure of claim 1 , wherein:
the first rail further comprising a first front post stop configured to interact with a front post of a cassette to assist seat the cassette into the cassette tray using the first rail; and
the second rail further comprising a second front post stop configured to interact with a front post of a cassette to assist seat a cassette into the cassette tray using the second rail.

14. The fiber enclosure of claim 1 , the second rail having a continuous length extending from a rear end and a front end of the second rail, the second rail further including a second routing member comprising the front end of the second rail wherein the second routing member is configured to route a cable at the front end of the fiber enclosure.
