Bidirectional coherent WDM-PON performance with real-time Nyquist 16QAM transmitter

This paper experimentally investigates the nonlinear performance and backscattering tolerance for a full-duplex bidirectional coherent WDM-PON with real-time Nyquist 16QAM transmitter. With 2×8×10 Gb/s over 50 km, the performance is evaluated for various pulse roll-off factors.
