Single-lane 180 Gb/s SSB-duobinary-PAM-4 signal transmission over 13 km SSMF

A 90 GBaud single sideband duobinary PAM-4 signal is generated using bandwidth pre-compensation and duo-binary pulse shaping employing a 92 GSa/s DAC. Transmission over 13 km of SSMF is achieved in 50 GHz channel enabled by dispersion pre-compensation at the transmitter.
