Low-cost in-band OSNR monitoring based on coherent hybrid in CO-OFDM system
2015 (English)In: CLEO: Science and Innovations, CLEO-SI 2015, 2015Conference paper (Refereed)
We proposed and demonstrated a cost-effective in-band optical signal to noise ratio (OSNR) monitoring technique based on coherent hybrid in 20Gb/s CO-OFDM system. Less than 0.5dB monitoring error is achieved with 400MHz balanced photodetector (PD).
