  • Patent number: 6926551
    Abstract: The invention features novel systems and methods for latching a pluggable transceiver to and unlatching the pluggable transceiver from a cage. In one aspect, a pluggable transceiver includes a housing and a cam. The housing has a front end configured to couple to a transmission cable and a back end configured to be inserted into a cage. The cam is disposed on an exposed outer surface of the transceiver housing and is configured to displace a cage latch and engage a cage slot upon insertion of the transceiver housing into the cage. In another aspect, a cage includes a housing and a latch. The housing has a front end for receiving a pluggable transceiver and defines a slot for engaging a transceiver cam. The latch is disposed at the front end of the cage housing.
