Abstract
The present invention relates to a cage for holding an optical transceiver module in electrical contact with a host circuit board. The cage includes front, middle and rear sections, and facilitates the insertion of the optical transceiver into the cage, as well as providing electromagnetic shielding and facilitating thermal dissipation. Typically, the cage is for use with an optical transceiver module including an integral heat sink cover or with an optical transceiver module including an external heat sink mounted over top of the cage. Various embodiments illustrate different schemes for maximizing heat dissipation by providing large openings in the middle section of the cage, as well as mounting surfaces on the front and rear sections for mounting external heat sinks. One or more crossbars are provided for guiding the transceiver module during insertion.
