According to an embodiment of the present invention, provided is a wavelength multiplexing bidirectional optical transmitting and receiving apparatus, which comprises: a light transmitting block; a band pass filtering unit for light transmission provided at one side of the light transmitting block; and a band pass filtering unit for light reception provided at one side or the other side of the light transmitting block. A light transmission signal incident to the light transmission block through the light transmission band pass filtering unit is reflected to the band pass filtering unit for light reception and emitted to the outside of the light transmission block. The light receiving signal incident from the outside and passing through the light transmitting block passes through the band pass filtering unit for light reception and is reflected by the band pass filtering unit for light transmission. 본 발명의 실시예에 따른 파장다중 양방향 광송수신 장치는 광 투과 블럭; 상기 광 투과 블럭의 일측에 구비된 광송신용 밴드패스필터링부; 및 상기 광 투과 블럭의 일측 또는 타측에 구비된 광수신용 밴드패스필터링부를 포함하며, 상기 광송신용 밴드패스필터링부를 통과하여 상기 광 투과 블럭으로 입사된 광 송신신호는 상기 광수신용 밴드패스 필터링부에 반사되어 상기 광 투과 블럭의 외부로 방출되고, 외부에서 입사되어 상기 광 투과 블럭을 통과하는 광 수신신호는 상기 광수신용 밴드패스필터링부를 통과하고 상기 광송신용 밴드패스 필터링부에 반사된다.
