Abstract
An SFP transceiver cage includes two sidewalls, a sidewall cover, a top plate, a bottom wall and a rear cover which are collectively preferably made from a single piece of metal plate, and an outer grounding plate. The outer grounding plate has a plurality of outward grounding spring tabs. A plurality of inward grounding spring tabs formed on the top plate project into the cage for contacting an SFP module. The inward and outward grounding spring tabs cooperate to provide multiple grounding paths and prevent EMI. A plurality of compliant legs, needle eye legs and support legs depends from the sidewalls. The compliant and needle eye legs are extended through a PCB, and prevent the cage from moving during solder reflowing. The support legs abut a face of the PCB. The support legs serve as standoffs, separating the cage from the PCB to facilitate accurate soldering.
