Abstract
An optical transceiver module is comprised of a mount substrate, a transmitting semiconductor laser, a receiving photodiode, a communicating hole, and a first filter. The mount substrate is provided so as to intersect with a predetermined axis X and has first and second principal surfaces facing each other. The transmitting semiconductor laser is mounted on the first principal surface and is configured to emit light of a first wavelength. The receiving photodiode is mounted on the predetermined axis X and on the second principal surface and is configured to receiving light of a second wavelength. The communicating hole is provided in a region of the mount substrate where the receiving photodiode is mounted, and makes the first and second principal surfaces communicate with each other.
