A bi-directional optical transceiver module includes an optical
transmitter, and an optical receiver, which have a TO-can structure, and
generates a first optical signal and detects a second optical signal,
respectively. A housing includes a first receiving section that receives
the optical transmitter. A second receiving section is arranged opposite
the first receiving section, a third receiving section is arranged below
the first and second receiving sections, and a fourth receiving section
is arranged opposite the third receiving section. The receiving stations
communicate through holes between the first through fourth receiving
sections. An optical fiber ferrule in the second receiving section
supports an optical fiber to input the second optical signal into the
bi-directional optical transceiver module. A block received in the fourth
receiving section and reflects the second optical signal received from
the optical fiber at a predetermined angle with respect to an optical
path of the first optical signal.
