Abstract: An optical transceiver module coupled to a device is provided. The optical transceiver module includes an electronic signal transmitting terminal coupled to a receiving terminal of the device, an electronic signal receiving terminal coupled to a transmitting terminal of the device, an optical signal receiving terminal coupled to the electronic signal transmitting terminal, and an optical signal transmitting terminal coupled to the electronic signal receiving terminal. When the optical transceiver module is at an normal operation state and the electronic signal receiving terminal does not receive any electronic signal over a first predetermined time period, the optical transceiver module enters a idle detection state to make the electronic signal transmitting terminal to perform a receiver termination detection to the device to determine whether the device is coupled to the optical transceiver module. At the idle detection state, the optical signal transmitting terminal transmits the optical signal continuously.
