A bi-directional optical transceiver module includes: an optical transmission unit to output a transmission signal; an optical reception unit to receive a reception signal, the transmission signal and the reception signal having different corresponding first and second wavelength values within a single channel; a splitter, inclined with respect to an incident direction of the transmission signal output from the optical transmission unit, to transmit the transmission signal to an outside, and reflect optical signals input from the outside, the optical signals including the reception signal; and a reflected light-blocking optical filter unit to pass, as the reception signal among the optical signals reflected by the splitter, an optical signal within a preset wavelength range including the second wavelength value.
