Unrepeatered Transmission of $10\times 400\text{G}$ Over 370 km via Amplification Map Optimization

We demonstrate unrepeatered transmission of 10 × 400-Gb/s PM-16QAM Nyquist wavelength-division multiplexing (WDM) dual-carrier superchannels (75-GHz flexigrid) at the SE = 5.33 b/s/Hz, where each superchannel is coherently detected by a single wideband receiver. A 350-km transmission is achieved by using optimized amplification map to efficiently design remote optically pumped amplifier and hybrid amplifiers. Additional digital domain nonlinear compensation allows to increase the transmission distance up to 370 km.
