Abstract
A passive optical network transceiver includes an avalanche photodiode, a bias voltage generator for supplying a bias voltage to the avalanche photodiode, a temperature detector for measuring the operating temperature of the avalanche photodiode, a memory for storing one reference bias voltage and a processing circuitry to process the value of the measured operating temperature and the reference bias voltage to generate a control signal for controlling the bias voltage generator to adjust the bias voltage supplied by the said bias voltage generator.
