Demonstration of 10-Gb/s, 5-GHz Spaced Coherent UDWDM-PON with Digital Signal Processing in Real-Time

This paper experimentally demonstrate the real-time field trial of 40×10-Gb/s coherent UDWDM-PON at 5-GHz spacing over 40-km field-installed fiber. The system stability is demonstrated by 8-hour real-time BER measurement with power budget of 29 dB.
