Pluggable optical transceiver with highly shielded structure
First Claim
1. 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 metal sleeve protruding in said optical receptacle;
a circuit board for installing an electronic circuit that electrically communicates with said optical assembly; and
a resin holder plated with metal, said resin holder fixing said optical assembly against said upper housing and said lower housing, wherein said upper and lower housings, said cover and said holder electrically shield said cavity to prevent noise generated by said electronic circuit from radiating outside of said transceiver and to prevent noise from invading into said transceiver.

Abstract
The present invention is to provide an intelligent pluggable transceiver improving an EMI tolerance with a simple mechanism. The optical transceiver of the invention comprises upper and lower housings (11, 12), a holder (81), optical assemblies (51, 61), a cover (14), a substrate (15) and a grip (13). The optical assemblies are fixed with the upper and lower housings together with the holder with interposing the conductive elastic member. Although the rear end of the substrate exposes outside the transceiver, the shield gasket and the ground pattern on the substrate shields the contact portion between the substrate and the upper housing and between the substrate and the cover. Moreover, the grip and the latch lever installed in the lower housing, and the elastic piece realize the latching/releasing mechanism of the transceiver with the host system.
