Air-cooled optical transceiver module system

摘要

In an opto-electronic system having one or more optical transceiver modules and an enclosure, air is forced through the interior of the transceiver module to dissipate heat generated by the opto-electronic and electronic elements.

主权项

1. An optical transceiver module system, comprising:
an enclosure having a plurality of bays, each bay having an elongated rectangular receptacle shape extending substantially along a longitudinal axis, each bay having a bay electrical connector; a cooling fan in the enclosure configured to convey air in a direction corresponding to the longitudinal axis; a transceiver module plugged into one of the bays, the transceiver module having a nose end and a tail end and extending between the nose end and the tail end in a direction corresponding to the longitudinal axis, the transceiver module comprising:
an electronics subassembly comprising a heat-emitting light source, a heat-emitting electronic device and a substrate having the light source and electronic device mounted thereon, the substrate having a plurality of signal conductors and a generally planar shape elongated in the direction corresponding to the longitudinal axis, the electronics subassembly mated with the bay electrical connector of the one of the bays into which the transceiver module is plugged;an elongated rectangular transceiver module housing assembly having a shape corresponding to the receptacle shape of the bay to provide a slideable fit with the bay, the transceiver module housing assembly extending between the nose end and the tail end of the transceiver module and having at least one optical receptacle disposed at the nose end of the transceiver module housing assembly for receiving a fiber-optic cable plug connector, the transceiver module housing assembly having a first airflow opening and a second airflow opening separated by an interior cavity portion of the transceiver module housing assembly extending in a direction corresponding to the longitudinal axis, wherein the light source is mounted in the interior cavity portion of the transceiver module housing assembly between the first airflow opening and the second airflow opening; andan optics subsystem in the transceiver module housing assembly configured to redirect an optical beam between the light source and the optical receptacle.
