Abstract
We have proposed and demonstrated a simple technique to monitor the OSNR in WDM networks. This technique has no pattern dependency and could measure the receiver noise power within the modulation bandwidth by using the orthogonal delayed-homodyne method. The results show that the proposed technique could measure the OSNR´s of WDM channels with accuracy better than 0.5 dB even after transmission over 640 km of single mode fibre.
