摘要：Disclosed is a bi-directional optical transceiver module. The bi-directionaloptical transceiver module includes: an optical transmission unit configured to output atransmission signal; an optical reception unit configured to receive an input of a receptionsignal, the transmission signal and the reception signal having different wavelengthvalues within a single channel; a splitter installed to be inclined with respect to an incidentdirection of the transmission signal output from the optical transmission unit to outputthe 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, onlyan 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 asto block external reflected light. The present disclosure may prevent a bi-directionaloptical transceiver module capable of preventing a link fail between optical

communication networks according to reflection and backscattering on an optical line.
