Patent ID: 7195403

Claim:
An optical transceiver having strengthened tolerance to electro-magnetic-induced noise, comprising: a metal upper housing; a metal lower housing forming an optical receptacle co-operating with said metal upper housing; a metal cover for forming a cavity cooperating with said upper and lower housings; an optical assembly having at least a metal sleeve protruding in said optical receptacle; a substrate for installing an electronic circuit that electrically communicates with said optical assembly, a portion of said substrate being enclosed within said cavity; and a resin holder plated with metal, and including a supporting portion, and a pair of latch arms extending from said supporting portion, said resin holder fixing said optical assembly against said upper housing and said lower housing, wherein said resin holder provides a conductive elastic member in said supporting portion to be put between said holder and said lower housing to prevent noise generated by said electronic circuit from radiating outside of said cavity and to prevent noise from invading into said cavity by electrically shielding said cavity.
