Single-channel 5.12 Tbit/s (1.28 Tbaud) DQPSK Transmission over 300 km Using Non-coherent Nyquist Pulses

摘要

We demonstrate a single-channel 5.12-Tbit/s, 300-km transmission using non-coherent Nyquist pulses with polarization-multiplexed DQPSK at 1.28 Tbaud. Despite this ultrahigh baud rate, we achieved a record distance at 5.12 Tbit/s thanks to the high PMD tolerance of the Nyquist pulse.
