Abstract

An in-band optical signal-to-noise ratio (OSNR) monitoring technique with high resolution and large measurement range is demonstrated based on lowbandwidth coherent receiver and a tunable laser. The measurement range of OSNR is from 10 to 25 dB and the resolution can be controlled about _1 dB.
