Patent ID: 7850373

Claim:
An optical block for reinforcing an optical block disposed on a circuit board and adapted to be connected to an optical connector, comprising: a pressure-receiving surface to which a pressure from the optical connector is applied when connecting the optical connector to the optical block, wherein the optical block reinforcing member comprises a separate body from the optical block and is adapted to be attached covering the optical block on the circuit board, wherein: the optical block comprises A) a block body, B) a first lens array on a front surface of the block body, the first lens array being adapted to be optically coupled with an optical fiber of the optical connector, C) a reflection surface in the block body for changing a propagation direction of an optical signal, and D) a second lens array on a bottom surface of the block body, the second lens array being adapted to be optically coupled with an optical element mounted on the circuit board; and the optical block reinforcing member is substantially C-shaped for covering both sides and a front face of the optical block and comprises an opening on a front face thereof, the opening being adapted to allow passage of an optical signal from the optical connector or the first lens array, wherein the pressure-receiving surface is formed around the opening.
