400.6-Gb/s PDM-BPSK Superchannel Transmission over 12,800-km TWRS Fiber via Nonlinear Noise Squeezing

We transmit a 406.6-Gb/s superchannel consisting of eight 37.5-GHz-spaced 32-Gbaud Nyquist-filtered PDM-BPSK signals over 12,800-km (160x80-km) EDFA-only amplified dispersion-unmanaged TWRS fiber. This result is enabled by nonlinear noise squeezing achieved through optimized digital electronic dispersion pre-compensation.
