International Classification:

H04B 10/00
H01J 40/14

US Classification:

398136, 250214 R

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.

Abstract:

A GPON module comprises a housing and a circuit board disposed in the housing. The circuit board further includes ground lines that substantially isolate regions of the circuit board, an electro-optical interface for converting an inbound optical signal to an electrical signal and processing circuitry that is arranged to provide an electrical RF signal to an RF interface. The RF interface comprises a three-pin RF connector exposed from the housing, wherein the RF connector is coupled directly to the circuit board, and two of the three pins are coupled to ground.
