Abstract:
1. An optical transceiver module comprising: a receiving unit outputting a receiver lost signal; a transmission driving unit comprising a positive receiving signal terminal and a negative receiving signal terminal; a first terminator impedance; a second terminator impedance, wherein the first terminator impedance and the second terminator are directly connected to a reference potential to form a differential terminator impedance; a first signal switch coupled between the positive receiving signal terminal and the first terminator impedance and controlling whether the positive receiving signal terminal is coupled to the first terminator impedance according to the receiver lost signal; and a second signal switch coupled between the negative receiving signal and the second terminator impedance and controlling whether the negative receiving signal terminal is coupled to the second terminator impedance according to the receiver lost signal; wherein when the optical transceiver module is coupled to an electronic transceiver through the positive receiving signal terminal and the negative receiving signal terminal and the differential terminator impedance is coupled between the positive receiving signal terminal and the negative receiving signal terminal, the electronic transceiver issues a link training sequence.
