BIDIRECTIONAL OPTICAL TRANSMITTING AND RECEIVING MODULE

Disclosed is a bi-directional optical transceiver module. The bi-directional optical transceiver module includes: an optical transmission unit configured to output a transmission signal; an optical reception unit configured to receive an input of a reception signal, the transmission signal and the reception signal having different wavelength values within a single channel; a splitter installed to be inclined with respect to an incident direction of the transmission signal output from the optical transmission unit to output the transmission signal to an outside and to reflect optical signals input from the outside; and a reflected light-blocking optical filter configured to pass, as a receiving signal, only an optical signal within a preset wavelength range including the wavelength value allocated to the reception signal among the optical signals reflected by the splitter so as to block external reflected light. The present disclosure may prevent a bi-directional optical transceiver module capable of preventing a link fail between optical communication networks according to reflection and backscattering on an optical line.
