The first and second coupling holes are large enough to respectively allow the optical output block and the optical transmitting block to be partially inserted thereinto. The optical output block is connected to an optical signal connector and is coupled to the first coupling hole of the housing. The optical transmitting block is connected to an electrical signal connector and is coupled to the second coupling hole of the housing.

The transmitting devices are laser diodes which oscillate optical signals having different wavelengths. The transmitting devices are arranged in a line to be parallel to the optical output block. Second lenses(132a-132d) are arranged on the light output side of the transmitting devices to correspond respectively to the transmitting devices. The second lenses are separated from the transmitting devices by a predetermined gap, and optical axes of the second lenses match output axes of the transmitting devices respectively. An optical MUX block(140) is disposed within the housing and between the optical is output block and the optical transmitting block. The optical MUX block multiplexes optical signals of multiple wavelengths, which were output from the transmitting devices and passed through the second lenses, and transmit the multiplexed optical signals to the optical output block.
