We propose and experimentally demonstrate a simple method for monitoring optical signal-to-noise ratio. The novel method can be used in the optical transport networks using optical cross-connects or reconfigurable optical add-drop multiplexers. OSNR is measured by monitoring the transmitted optical power and the reflected optical power from fiber Bragg grating. We have obtained OSNR with an error less than 0.8 dB.
