Small form-factor pluggable transceiver cage

Claim 1

A small form-factor pluggable transceiver cage adapted to be mounted to a panel, the cage comprising: a mainframe including a top plate, a bottom wall opposite to the top plate forming a spring latch, and first and second parallel sidewalls between the top plate and the bottom wall, the first sidewall integrally connected to the bottom wall, and the second sidewall integrally connected to both the bottom wall and the top plate, the mainframe further including a rear cover, and a sidewall cover depending from one edge of the top plate and at least partially overlapping the first sidewall; a grounding device mounted to an entrance of the mainframe, the grounding device including at least one outward spring tab disposed below a spring latch of the mainframe and adapted to contact a face of the panel; last line, the period has been changed to a semicolon and the following paragraphs have been inserted thereafter: wherein the grounding device is dimensioned to closely fit over a front portion of the mainframe; wherein the grounding device is made from a single piece of metallic material; wherein the grounding device is spot welded to a front portion of the mainframe; wherein the grounding device is hooked onto a front portion of the mainframe with at least one hook; wherein the mainframe is made from a single piece of metallic material; wherein a plurality of inward grounding fingers are formed on a front portion of the mainframe; wherein the inward grounding fingers project into the cage for contacting a corresponding transceiver module, thereby providing multiple grounding paths and preventing electromagnetic interference.
