摘要
An apparatus and method for measuring optical signal to noise ratio (OSNR) in a node of an optical data network is disclosed. A peak power level and an average power level are measured for an optical input to an optical detector. The OSNR is determined by selecting an OSNR having the peak power level and the average power level associated with an optical signal traversing an optical path having attenuation and optical amplifier noise.
