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.
