Patent ID: 7536075

Claim:
A telecommunications assembly comprising: a chassis and a module mounted within the chassis; the chassis including: a housing with a top, a bottom, and opposing sides, defining an interior space accessible through an open front, the housing including a back opposite the open front; a plurality of mounting locations within the interior space; at least one fiber optic adapter corresponding to each of the mounting locations mounted within the interior space, the fiber optic adapters each including a front end directed toward the open front and a back end directed toward the back, each front end and each back end configured to receive a fiber optic connector; and, the fiber optic adapters mounted to an adapter assembly mounted to the chassis, the adapter assembly removable from the interior space of the chassis; and, the module mounted at one of the mounting locations and including: a housing defining an interior and a rear face to which is mounted at least one fiber optic connector engaging the at least one fiber optic adapter of the chassis, wherein the at least one fiber optic connector projects rearwardly from the rear face, the housing also defining a cable exit; and an optical wavelength division multiplexer/demultiplexer mounted within the interior of the housing, a first fiber optic cable within the interior of the housing extending from the at least one fiber optic connector to the optical wavelength division multiplexer/demultiplexer mounted within the interior of the housing and a second fiber optic cable extending from the optical wavelength division multiplexer/demultiplexer to an outside of the housing through the cable exit; wherein the module is mounted within the chassis housing separately from the removable fiber optic adapter assembly such that the at least one fiber optic connector of the module engages the at least one fiber optic adapter mounted to the chassis when the module is mounted within the chassis housing, wherein the chassis includes a flexible shield for blocking light off a front end of an adapter of the adapter assembly, 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 module when the module is slidably inserted within the chassis.
