  • Patent number: 7131859
    Abstract: The invention relates to an optical transceiver system for use in a host device including an optical transceiver receptacle or cage with a heat dissipating structure mounted thereon. The heat dissipating structure is electronically powered by an external source in the host device, which are electrically connected by insertion of a transceiver module into the transceiver receptacle. The present invention enables optical transceivers to support very high data rates, e.g. >8 Gb/s, while still supporting very high density applications, e.g. SFF/SFP. Actuating features on the transceiver module and cage enable the heat dissipating structure to be turned on when the transceiver module is fully inserted into the cage, and turned off when the transceiver module is removed or at least partially removed from the cage.

  • Patent number: 6666484
    Abstract: A push-to-release latching mechanism for retaining a transceiver module in a communication port of a computer or server is provided with a beam spring structure for positional restoration of the latch member, and the latch is supported and moveable relative to the host transceiver module. The latch member may be formed to include camming surfaces that facilitate the insertion of the transceiver module into a communication port and mate with a guide rail and connector resident in a communication port. The latch member may be adapted to latch with a rigid latch bar or a cantilevered spring. Additionally, the latch may be formed with a camming surface which insures that the latch is displaced to a latching position whenever network cables are connected to the transceiver module by camming the latch into the secure, latched position and subsequently preventing the latch from moving to an insecure or unlatched position.
