Abstract :
In-band OSNR measurement for IM/DD O-OFDM systems using high-resolution spectral analysis is experimentally demonstrated. It is shown that noise level can be monitored by direct optical spectrum analysis using no polarization analysis or coherence properties and avoiding the need for data demodulation.
