Fiber optic module and system including rear connectors
A telecommunications assembly including a housing and a plurality of modules mounted within the housing. The modules includes a rear face in which is mounted at least one fiber optic connector. Within an interior of the housing are positioned at least one fiber optic adapters. Inserting the module through a front opening of the housing at a mounting location positions the connector of the module for insertion into and mating with the adapter of the housing. The adapters within the interior of the housing are mounted to a removable holder. A method of mounting a telecommunications module within a chassis.
1. A fiber optic telecommunications assembly comprising:
(a) a housing defining an open front and a back opposite the open front;
(b) at least one fiber optic adapter mounted to the housing, the fiber optic adapter configured to mate with a telecommunications module inserted through the front of the housing, the fiber optic adapter including a front end and a rear end, each end of the fiber optic adapter configured to receive a mating fiber optic connector, the front end positioned to receive a first mating fiber optic connector of the telecommunications module inserted through the front toward the back and the rear end positioned to receive a second mating fiber optic connector of a fiber optic cable; and
(c) a telecommunications module mounted to the housing, the telecommunications module including:
a module housing defining a front end and a rear end; and
the first mating fiber optic connector, the first mating fiber optic connector being mounted to the module housing at an intermediate mounting location forwardly offset from the rear end of the module housing and rearwardly offset from the front end of the module housing, the fiber optic connector having an interface end that faces in a rearward direction, the interface end of the fiber optic connector being accessible from outside the module housing and including a ferrule;
(d) wherein the telecommunications module is mounted within the
housing separately from the fiber optic adapter such that the ferrule of the first mating fiber optic connector of the telecommunications module engages the fiber optic adapter mounted to the housing when the telecommunications module is mounted to the housing.
2. A fiber optic telecommunications assembly according to claim 1 , wherein the telecommunications module includes a flexible latching tab for being removably mounted to the housing with a snap-fit interlock.
3. A fiber optic telecommunications assembly according to claim 1 , wherein the telecommunications module includes at least one optical component, a first optical fiber cable extending from the first mating fiber optic connector to the optical component and at least one second optical fiber cable extending from the optical component to a cable exit location of the telecommunications module.
4. A fiber optic telecommunications assembly according to claim 3 , wherein the optical component is an optical splitter, the first optical fiber cable includes a single strand of fiber and a plurality of second optical fiber cables extend from the optical component to the cable exit location of the telecommunications module.
5. A fiber optic telecommunications assembly according to claim 1 , wherein the at least one fiber optic adapter is removably mounted to the housing.
6. A fiber optic telecommunications assembly according to claim 1 , wherein the cable exit location of the telecommunications module is at the front end.
7. A fiber optic telecommunications assembly according to claim 1 , wherein the housing defines a plurality of mounting locations and at least one fiber optic adapter mounted at each of the mounting locations.
8. A fiber optic telecommunications assembly according to claim 7 , further comprising a plurality of the telecommunications modules mounted to the housing.
9. A fiber optic telecommunications assembly according to claim 7 , wherein the telecommunications module includes a pair of opposing mounting flanges and each mounting location includes a pair of opposing slots for receiving the mounting flanges, one of the mounting flanges being larger than the other and only one of the slots being sized to receive the larger flange.
