Abstract
An optical transceiver module includes a receiving unit, a transmission driving unit, and a terminal control unit. The receiving unit outputs a receiver lost signal. The transmission driving unit includes a positive receiving signal terminal and a negative receiving signal terminal. The terminal control unit is coupled between the positive receiving signal terminal and the negative receiving signal terminal. The terminal control unit controls whether a differential terminator impedance is coupled between the positive receiving signal terminal and the negative receiving signal terminal according to the receiver lost signal.
