Claim:
1. An optical transceiver that is to be plugged into a cage of a host system, comprising: a multi-fiber push-on (MPO) connector that receives an external optical connector; an assembly substrate having a primary surface, the assembly substrate mounting a holder and at least a semiconductor optical device on the primary surface thereof, the semiconductor optical device having an optical axis substantially in perpendicular to the primary surface of the assembly substrate; a lens block mounted on the primary surface of the assembly substrate, the lens block bending the optical axis of the semiconductor optical device toward a direction substantially in parallel to the primary surface of the assembly substrate; a circuit board that mounts electronic circuits electrically coupled with the semiconductor optical device; at least an inner fiber that couples the lens block with the MPO connector; and a housing including a top housing and a bottom housing that form an inner space enclosing the MPO connector, the assembly substrate, the lens block, the circuit board, and the inner fiber therein, wherein the bottom housing mounts the circuit board thereon and the top housing is thermally and physically in contact to the assembly substrate, wherein the optical transceiver provides a plurality of the inner fibers in an arrayed form, wherein the assembly substrate mounts a plurality of the semiconductor optical devices, wherein the lens block provides a plurality of lens elements coupled with the respective semiconductor optical devices, wherein the arrayed fiber provides a first mechanically transferable (MT) ferrule in an end thereof, and a second MT ferrule in another end thereof, the first MT ferrule coupling with the MPO connector, the second MT ferrule coupling with the lens block, and wherein the holder surrounds the lens block.
