Optical transceiver module with multiple grounding paths

An optical transceiver module comprises a base, a pair of metallic releasable latches attached to opposite lateral sides of the base, and a housing. The housing includes an upper housing and a lower housing, which are mounted to an upper side and a lower side of the base respectively. Each latch includes a retention portion, and a spring portion bent generally perpendicularly from an outer end of the retention portion. The retention portions of the latches are inserted into receiving grooves defined in side walls of the base. The spring portions of the latches sit on the side steps of the base. The upper housing electrically engages with rear parts of the spring portions. Any electrostatic charge that develops on the upper and lower housings is dissipated to external ground via the latches.
