Claim Text:
1. An optical transceiver, comprising: an electric terminal configured to receive power from a host equipment and to provide a power supply voltage to the optical transceiver; a power failure monitor circuit integrated in the optical transceiver, where the power failure monitor circuit is configured to detect an imminent loss of the power supply voltage, wherein the power failure monitor circuit is configured to produce a dying-gasp control signal when such imminent loss of power supply voltage is detected or when a disabling control signal is received from the host equipment; a driver configured to receive output data and the dying-gasp control signal; and an optical transmitter powered by the power supply voltage and configured to emit a first optical signal under the control of the driver, wherein the driver and the optical transmitter are configured to produce an optical-layer dying-gasp signal in response to the dying-gasp control signal.
