The disclosed optical receive module with overload protection function comprises: an avalanche photodiode with reverse offset voltage provided by a DC/DC boost-up circuit, a sample resistance with one end connected with the output end of said boost-up circuit and another end connected a limit current protective resistance with larger resistance value than the sample one in series with the reverse off-set voltage tube pin. When the input optical power is too high, it produces large photocurrent to enlarge the voltage drop on said protective resistance to lead the reverse off-set voltage of avalanche photodiode lowering rapidly to make it can not produce avalanche effect and avoid overcurrent damage.
