The invention discloses an optical receiver module sensitivity estimation method and system. The optical receiver module sensitivity estimation method comprises the steps of: obtaining a formula (with reference to the specification); by taking 1g[-1g(BER)] as a variable and taking 101g(Sen.delta) as an independent variable, obtaining a curve; selecting a curve segment on the curve, and obtaining a fitting linear equation that y=ax+b; and obtaining a set value BER of an optical module and rho, re and in, calculating a sensitivity Sen, and obtaining an estimated value. The sensitivity estimation method disclosed by the invention breaks a conventional complex sensitivity estimation mode, simplifies a sensitivity estimation formula, is convenient for sensitivity estimation, solves the problem of difficulty in sensitivity estimation, carries out calculation on the sensitivity according to the obtained equation, is simple and convenient, does not need to consider a signal-to-noise ratio and is convenient to process
