Abstract

A fiber optic telecommunications device includes a frame and a fiber optic module including a rack mount portion, a center portion, and a main housing portion. The rack mount portion is stationarily coupled to the frame, the center portion is slidably coupled to the rack mount portion along a sliding direction, and the main housing portion is slidably coupled to the center portion along the sliding direction. The main housing portion of the fiber optic module includes fiber optic connection locations for connecting cables to be routed through the frame. The center portion of the fiber optic module includes a radius limiter for guiding cables between the main housing portion and the frame, the center portion also including a latch for unlatching the center portion for slidable movement. Slidable movement of the center portion with respect to the rack mount portion moves the main housing portion with respect to the frame along the sliding direction.

First claim

The invention claimed is:

1. A telecommunications module comprising:
a fixture;
a fiber optic cassette mounted to the fixture via a first snap-fit interlock structure, the fiber optic cassette including:
a body defining a front and an opposite rear and an enclosed interior;
a fiber optic signal entry location defined on the body for a fiber optic signal to enter the interior of the cassette via a fiber optic cable;
an adapter block defining a plurality of fiber optic adapters, the adapter block removably mounted to the cassette body via a second snap-fit interlock structure, each adapter of the block including a front outer end, a rear inner end, and internal structures which allow mating of fiber optic connectors that are mounted to the front and rear ends, respectively;
optical fibers terminated with fiber optic connectors extending from the fiber optic signal entry location to the rear inner ends of at least some of the fiber optic adapters of the snap-fit adapter block for relaying the fiber optic signal to fiber optic connectors to be coupled to the front outer ends of the adapters;
wherein at least a portion of the first snap-fit interlock structure is defined by the adapter block.

2. A telecommunications module according to claim 1 , wherein the first snap-fit interlock structure is configured to allow the adapter block to be mounted to the fixture without the remainder of the fiber optic cassette.
