Abstract:
1. A mechanism to dissipate heat from a pluggable optical transceiver set in a cage to a heat sink assembled with said cage through a thermo-conducting sheet put between said transceiver and said heat sink, said mechanism comprising: at least a projection provided in a rear end of said optical transceiver; at least a rail with a pocket provided in said heat sink; and a mechanism provided in said cage and said heat sink to cause a downward force to said heat sink, wherein said projection first lifts said heat sink upward against said downward force by running on said rail of said heat sink when said optical transceiver is inserted into said cage, and wherein said projection finally is set within said pocket of said heat sink to have said thermo-conducting sheet come in contact to said optical transceiver when said optical transceiver is set in a final position within said cage.
