Abstract
The invention relates to a latch device for a pluggable opto-electronic module, such as an optical transceiver, for locking the module in a rail or cage system of a host machine. The latest generation of optical transceivers include all metal housings, instead of all plastic or partial plastic, to ensure adequate heat dissipation. The relatively heavier housings necessitate the use of more robust latch devices. The latch device according to the present invention includes a sliding element with arms extending therefrom for pivoting a latching hook out of engagement with the rail or cage system. In a preferred embodiment, a pair of latching hooks are provided, one on each side of the module. The latching hooks are mounted on the ends of spring arms, which extend from the same sheet of spring metal positioned across the bottom of the housing.
