Abstract:
1. An optical transceiver having a 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; and a substrate including first and second portions each within said cavity and a third portion 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 the other side of a first surface of said substrate, said first conductor being provided so as to intersect a longitudinal axis of said optical transceiver, wherein said upper and lower housings are electrically connected with said first conductor, and at least one of said upper and lower housings comes in uniform contact with said first conductor to shield said cavity, to prevent noise generated by said electronic circuit from radiating outside of said cavity, and to prevent noise from invading into said cavity.
