Abstract

A telecommunications assembly includes a chassis and a plurality of modules removably mounted within the chassis. The modules include one or more fiber optic signal input locations. The modules include optical equipment for splitting the input signals into customer output signals.

Claims

1. A telecommunications module comprising:

a housing having a main housing portion and a removable cover cooperatively defining an interior, the main housing portion defining a first sidewall, a front wall, a rear wall, a top wall, and a bottom wall, the cover defining a second sidewall of the housing when mounted on the main housing portion to close off the interior, the main housing portion including at least one signal output location defined on the front wall;

an optical component located within the interior, the optical component configured to receive a fiber optic input signal coming in from a signal input location of the housing and output a fiber optic output signal going toward the signal output location defined on the front wall of the main housing portion, wherein the telecommunications module is configured such that the signal input location can be selected to be on either the front wall or the rear wall of the main housing portion;

a friction clamp located within the interior for removably mounting the optical component to the main housing portion, the friction clamp configured to slidably receive the optical component and retain the optical component within the interior via friction; and

a cable exit structure defining a curved top wall and a curved bottom wall, wherein the curved top and bottom walls collectively provide a bell-shaped configuration for the cable exit structure, the cable exit structure defining the signal output location on the front wall, the cable exit structure defining an integrally formed unitary structure extending from the top wall to the bottom wall of the main housing portion, the curved top wall and the curved bottom wall of the cable exit structure forming the bell shaped configuration providing bend radius protection to optical fiber cables carrying the fiber optic output signal, wherein the telecommunications module further comprises a flexible latch for mounting to a telecommunications fixture with a snap-fit interlock, wherein at least one of the curved top wall and the curved bottom wall of the cable exit structure is adjacent the flexible latch, and a curvature of at least one of the top wall and the bottom wall provides spacing for allowing flexing of the latch for unlocking the telecommunications module from the telecommunications fixture.

2. A telecommunications module according to claim 1, wherein the telecommunications module is configured as a rear input module such that the signal input location is defined by a connector that protrudes from the rear wall of the main housing portion, the connector configured for mating with a fiber optic adapter.

3. A telecommunications module according to claim 1, wherein a height of the telecommunications module is defined between the top wall and the bottom wall, the height being between 2 and 3 inches and configured to fit within one standard unit (RU) of rack space in a standard telecommunications rack.

4. A telecommunications module according to claim 1, wherein the module includes a fiber optic splitter within the module, the fiber optic splitter configured to split a single signal incoming into the module into a plurality of same outgoing signals.

5. A telecommunications module according to claim 1, wherein the flexible latch of the telecommunications module is defined adjacent the top wall of the main housing portion, the telecommunications module further including a fixed handle adjacent the bottom wall of the main housing portion opposite the flexible latch.
