Abstract

A telecommunications module includes a main housing portion and a cover, 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 when mounted on the main housing portion. An optical component located within the module receives an input signal from a signal input location of the housing and outputs an output signal toward a signal output location on the front wall. The telecommunications module is configured such that the signal input location can be selected to be either on the front wall or the rear wall of the main housing. The cover defines a protrusion extending from the second sidewall toward the main housing portion, the protrusion being selectively breakable to expose a recess on the front wall of the main housing portion that defines a signal input location.

First claim

What is claimed is:

1. A telecommunications module comprising:
a housing including a removable cover to define an interior of the housing, the housing further defining a front wall, an opposite rear wall, and two walls connecting the front wall to the rear wall;
an optical component located within the interior, the optical component configured to receive and process a fiber optic input signal coming in from a signal input location that is located at the front wall of the housing, wherein a signal output location is also located at the front wall of the housing for exiting an output signal that has been processed by the optical component, wherein both the signal input location for entering the fiber optic input signal to be processed by the optical component and the signal output location for exiting the output signal are defined by a flexible boot structure protruding from the front wall of the housing; and
a flexible latch defined on at least one of the two walls connecting the front wall to the rear wall of the housing for mounting the module to a telecommunications chassis with a snap-fit interlock.

2. The telecommunications module of claim 1 , wherein the optical component includes an optical wavelength division multiplexer/demultiplexer.

3. The telecommunications module of claim 1 , wherein the optical component includes a fiber optic splitter that splits the fiber optic input signal into a plurality of the fiber optic output signals.

4. The telecommunications module of claim 1 , wherein the housing includes at least one cable management structure for guiding a cable carrying the fiber optic input signal between the signal input location and the optical component.

5. The telecommunications module of claim 4 , wherein the at least one cable management structure includes a spool defining a curved wall.

6. The telecommunications module of claim 1 , wherein the housing includes at least one cable management structure for guiding a cable carrying the output signal between the optical component and the signal output location.

7. The telecommunications module of claim 6 , wherein the at least one cable management structure is located adjacent the rear wall of the housing and includes a curved wall.

8. The telecommunications module of claim 1 , wherein the cover defines protrusion extending therefrom toward the housing, the protrusion received within a recess defined on the front wall when the cover is mounted to the housing, the protrusion selectively breakable to expose the recess on the front wall to define at least one signal input location.

9. The telecommunications module of claim 8 , wherein the protrusion includes two breakable portions separated by a break line, the breakable portions include a base portion and a tip portion, wherein, if one input cable carrying a fiber optic input signal is desired to enter the housing, the tip portion is adapted to be selectively broken off and if two input cables carrying fiber optic input signals are desired to enter the housing, the protrusion is selectively broken off at the base portion to remove the entire protrusion.
