Fiber optic module and system including rear connectors

A fiber optic telecommunications assembly comprising:

• (a) a chassis defining at least one mounting location;
• (b) at least one fiber optic adapter corresponding to each mounting location of the chassis, the fiber optic adapter including a front end and a rear end, each end of the at least one fiber optic adapter configured to receive a mating fiber optic connector, the front end positioned to receive a fiber optic connector of a telecommunications module that is to be inserted into the chassis and mounted at the at least one mounting location;
• and
• (c) a telecommunications module mounted to the chassis at one of the mounting locations, the telecommunications module including:
• (i) a module housing;
• (ii) a fiber optic connector for inputting a fiber optic signal into the telecommunications module, the fiber optic connector having an interface end that is accessible from outside the module housing, the fiber optic connector including a ferrule;
• (iii) an input fiber routed from the fiber optic connector into the module housing;
• and
• (iv) an output fiber routed toward a fiber output location of the module housing;
• (v) wherein the fiber optic connector of the telecommunications module includes an inner housing mounted inside an outer housing, the inner housing supporting the ferrule, the ferrule defining a connector axis that extends longitudinally through the ferrule, the outer housing being anchored to the module housing by a connection that restricts movement of the outer housing relative to the module housing along the connector axis;
• (d) wherein the telecommunications module is mounted to the chassis at one of the mounting locations such that the ferrule of the fiber optic connector of the telecommunications module engages the at least one fiber optic adapter of the corresponding mounting location when the telecommunications module is mounted to the chassis.
