Popis:	We propose and demonstrate a simple technique to monitor the optical signal-to-noise ratio (OSNR) of WDM signals by analyzing the high-frequency receiver noise above the modulation frequency. The results show that the OSNR of WDM signals could be monitored with an accuracy better than 1 dB even after transmission over 640 km of single-mode fiber.
