Abstract
A system and method for in-service optical signal-to-noise ratio (OSNR) testing in optical communication systems. At least one OSNR test signal is combined onto an optical path with data channels. A receiver detects the received power of the OSNR test signal and provides output data representative of the OSNR of the system.
