Intelligent pluggable optical transceiver

An optical transceiver having strengthened tolerance to electro-magnetic-induced noise, comprising:

• a metal upper housing including a shield gasket at a rear end thereof;
• a metal lower housing forming an optical receptacle cooperating with said metal upper housing;
• a metal cover for forming a cavity cooperating with said upper and lower housings;
• an optical assembly;
• and
• a substrate including first and second portions each put within said cavity and a third portion put outside of said cavity, said first and second portions installing an electronic circuit communicating with said optical assembly, said second portion being divided from said third portion by a first conductor extending from a side to another side of a first surface of said substrate,
• wherein said shield gasket comes in uniform contact to said first conductor on said first surface of said substrate to shield said cavity and to prevent noise generated by said electronic circuit from radiating outside of said cavity and to prevent noise from invading into said cavity.

• a metal upper housing;
• a metal lower housing forming an optical receptacle cooperating with said metal upper housing;
• a metal cover for forming a cavity cooperating with said upper and lower housings, said metal cover including a plurality of conductive tabs at a rear end thereof, the conductive tabs each having a tip portion bent inward of said cavity;
• an optical assembly;
• and
• a substrate including first and second portions each put within said cavity and a third portion put outside of said cavity, said first and second portions installing an electronic circuit communicating with said optical assembly, said second portion being divided from said third portion by a first conductor extending from a side to another side of a first surface of said substrate,
• wherein said bent tip portion of said conductive tabs comes in contact with said first conductor on said first surface of said substrate to shield said cavity and to prevent noise generated by said electronic circuit from radiating outside of said cavity and to prevent noise from invading into said cavity.
