200 Gb/s and dual-wavelength 400 Gb/s transmission over transpacific distance at 6 b/s/Hz spectral efficiency

We transmit 106×200 Gb/s channels over 10,290 km at 6.0 b/s/Hz enabled by Nyquist spectral shaping and nonlinearity compensation. We also transmit 53×400 Gb/s channels over 9,200 km detecting two 200 Gb/s wavelengths simultaneously using a wideband receiver.
