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 assembly comprising:

A. a chassis defining a plurality of mounting locations for slidably receiving telecommunications modules; and

B. a telecommunications module inserted into one of the mounting locations of the chassis, the telecommunications module comprising;

i. a housing having a main housing portion and a removable cover cooperatively defining an interior, the main housing portion defining a first sidewall, 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;

ii. 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; and

iii. a friction clamp located within the interior for removably mounting the optical component to the main housing portion, the friction clamp including a U-shaped rubber gasket that includes a top portion, a bottom portion, and a connector portion that connects the top portion to the bottom portion, the rubber gasket being slidably inserted between an upper clamp wall and a lower clamp wall defined within the main housing portion, wherein the upper clamp wall and the lower clamp wall define opposing notches, and the rubber gasket defines keying tabs on the top and bottom portions thereof for slidable mating with the notches of the upper and lower clamp walls, the rubber gasket defining an open end facing toward the second sidewall defined by the cover, the friction clamp configured to slidably receive the optical component through the open end of the rubber gasket and retain the optical component within the interior solely via frictional force from both the top portion and the bottom portion of the U-shaped rubber gasket, wherein the optical component is mounted to the main housing portion such that the optical component is not received within the main housing portion without first contacting the rubber gasket.

2. A telecommunications assembly according to claim 1, wherein a fiber optic adapter that is mounted to the chassis separately from the telecommunications module is configured to mate with a connector that protrudes from the main housing portion when the telecommunications module is inserted into the chassis.

3. A telecommunications assembly according to claim 2, wherein each mounting location includes a spring-loaded shield for blocking light off a front end of the fiber optic adapter, the shield movable between an operating position and a non-operating position, the shield configured to be moved from the operating position to the non-operating position by the telecommunications module when the module is slidably inserted within the chassis.

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

5. A telecommunications assembly according to claim 1, wherein the chassis includes a latch slot, the latch slot configured to receive a portion of a flexible latch of the telecommunications module for forming a snap fit interlock with the module for retaining the module within the chassis.

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

7. A telecommunications assembly according to claim 1, wherein the chassis includes a plurality of the telecommunication modules inserted into the chassis.

8. A telecommunications assembly 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.

9. A telecommunications assembly according to claim 1, wherein the telecommunications module defines an opening for receiving optical fiber cables carrying the fiber optic input signal.

10. A telecommunications assembly according to claim 1, wherein the telecommunications module further comprises a cable exit structure including a bell-shaped portion defining the signal output location, the bell shaped portion configured to provide bend radius protection to optical fiber cables carrying the fiber optic output signal.

11. 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, 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;

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; and

a friction clamp located within the interior for removably mounting the optical component to the main housing portion, the friction clamp including a U-shaped rubber gasket that includes a top portion, a bottom portion, and a connector portion that connects the top portion to the bottom portion, the rubber gasket being slidably inserted between an upper clamp wall and a lower clamp wall defined within the main housing portion, wherein the upper clamp wall and the lower clamp wall define opposing notches, and the rubber gasket defines keying tabs on the top and bottom portions thereof for slidable mating with the notches of the upper and lower clamp walls, the rubber gasket defining an open end facing toward the second sidewall defined by the cover, the friction clamp configured to slidably receive the optical component through the open end of the rubber gasket and retain the optical component within the interior solely via frictional force from both the top portion and the bottom portion of the U-shaped rubber gasket, wherein the optical component is mounted to the main housing portion such that the optical component is not received within the main housing portion without first contacting the rubber gasket.

12. A telecommunications module according to claim 11, wherein the signal input location is defined by a connector that protrudes from the main housing portion, the connector configured for mating with a fiber optic adapter.

13. A telecommunications module according to claim 11, wherein a height of the telecommunications module is between 2 and 3 inches and configured to fit within one standard unit (RU) of rack space in a standard telecommunications rack.

14. A telecommunications module according to claim 11, further comprising a flexible latch for mounting to a telecommunications fixture with a snap-fit interlock.

15. A telecommunications module according to claim 11, 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.
