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.
