Abstract

We transmit 106 × 200 Gb/s channels over 10 290 km at 6.0 b/s/Hz enabled by Nyquist spectral shaping and digital back propagation (DBP). 53 × 400 Gb/s channels are also transmitted over 9200 km detecting two 200 Gb/s wavelengths simultaneously using a wideband receiver. DBP benefit versus channel pre-emphasis, average launch power per channel, and transmission distance are experimentally investigated. We find the DBP benefit scales monotonically with channel power and transmission distance. Measurement results match well with theory.
