1-Tbit/s dual-carrier DP 64QAM transmission at 64Gbaud with 40% overhead soft-FEC over 320km SSMF

We demonstrate 1-Tbit/s dual-carrier dual-polarization 64QAM transmission at 64Gbaud over 320km of standard single-mode fiber with EDFAs only. Error free performance is validated by sFEC decoding of the received data after fiber transmission.
