Patent ID: 6894903

Claim:
An optical data link comprising: a mounting member having a substrate with a plurality of holes, and a plurality of electrically conductive pins passing through said plurality of holes of said substrate; a circuit board having a pair of surfaces with an electrically conductive layer connected to at least one pin of said plurality of electrically conductive pins, each of said pair of surfaces mounting an electronic component; an optical element assembly, mounted on said mounting member, including a semiconductor optical element connected to said electrically conductive layer provided on said circuit board; a first support member located along one side of said circuit board and being provided between said circuit board and said mounting member for supporting said circuit board, said first support member having a thickness substantially equal to an interval between said circuit board and said mounting member; and a second support member located along an opposite side of said circuit board and being provided between said circuit board and said mounting member for supporting said circuit board, said second support member having a thickness substantially equal to said interval between said circuit board and said mounting member; wherein said circuit board has a cutout so as to receive a tail of said optical element assembly, said first support member holding said optical element assembly on two sides.
