Abstract
An optical transceiver provides a TOSA, a ROSA, a base member, a circuit board and a shield member. The shield member is formed by cutting and bending a metal sheet without welding or soldering. The shield member includes a center partition and a pair of sides, which forms two spaces each receiving the TOSA or the ROSA. The center partition has a V-shaped cross section which is able to be inserted into a cut of the circuit board so as to shield the ROSA from the TOSA. The shield member provides a frame ground by being in the bottom of the center partition in contact with the base member and also in contact with the cover.
Claims15
An optical transceiver, comprising:
- a transmitter optical sub-assembly (TOSA);
- a receiver optical sub-assembly (ROSA);
- a shield member with a center partition and a pair of sides, said center partition including two walls and a bottom configured to connect said walls, one of said walls forming a first space accompanied with one of said sides, and another of said walls forming a second space accompanied with another of said sides, wherein said TOSA is set in said first space and said ROSA is set in said second space;
- a circuit board electrically connected with said TOSA and said ROSA, said circuit board including a center cut;
- and
- a base member configured to mount said circuit board and said shield member thereon,
- wherein said bottom of said center partition comes into physical contact with said base member by passing said two walls through said center cut of said circuit board.
