Abstract
Provided is an optical transceiver module having a dual band pass WDM coupler embedded therein, wherein the dual band pass WDM coupler provides pass bands for selectively passing a transmission signal output from an optical transmitting unit, and an optical signal having a specific wavelength received by an optical receiving unit among optical signals input through a common port. According to the present invention, a size and cross-talk of the optical transceiver module may be reduced, and the optical transceiver module may be used as a video transceiver in an optical subscriber network according to an ITU-RG.983.3 standard.
