Sfp transceiver equipped with deep drawn metal emi sleeve around mating portion of lens module

An SFP (Small Form Factor Pluggable) transceiver comprising:

• a metallic housing made by a die-casting process and a metallic upper cover made by forming sheet metal, being assemble to each other to commonly define a receiving cavity therebetween;
• a mating port defined at one end of the housing for coupling to an optical connector;
• a printed circuit board assembly disposed in the receiving cavity and including:
• a printed circuit board with an insulative lens structure around the mating port, said lens structure including a front face with at least one tubular structure forwardly extending therefrom in a front-to-back direction;
• a metallic EMI shielding device including a plate with at least one sleeve forwardly extending therefrom via a deep drawing process:
• wherein
• the plate covers the front face in the front-to-back direction, and the sleeve covers the tubular structure circumferentially.
