Transmission reach doubling enabled by transmitter-side digital back propagation and frequency referenced carriers

A 100% reach extension in a coherent Wavelength Division Multiplexing link is demonstrated relying on transmitter-side full-field Digital Back-Propagation and frequency referenced carriers. Transmission reach is extended from 1445 km to 2890 km for a 4-channel 16 GBaud 16-QAM system.
