Zusammenfassung:	According to the present invention, a light transmitting and receiving module has an internal dual band pass WDM coupler for providing a pass band to selectively pass a light signal of a specific wavelength received in a light receiving unit among light signals received through a common port. According to the present invention, the size and crosstalk of the light transmitting and receiving module can be reduced, and the light transmitting and receiving module can be used as a video transceiver in a light subscriber network following a specification of ITU-RG.983.3. 본 발명에 따른 광 송수신 모듈에는 광 송신부로부터 출력되는 송신신호와, 공용 포트를 통해 입력되는 광신호 중 광 수신부에서 수신하는 특정 파장의 광신호를 선별적으로 통과시키기 위한 통과대역을 제공하는 듀얼 대역통과 WDM 커플러가 내장되어 있다. 이러한 본 발명에 의하면 광 송수신 모듈의 크기 및 누화를 감소시킬 수 있으며, ITU-RG.983.3 규격을 따르는 광 가입자 망에서 비디오 송수신기로서 사용될 수 있다.
