336-Tbit/s Real-time Transmission over 332-km 7-Core Fibre Based on 400-Gbit/s CFP2-DCO Silicon Photonics Transceiver

We demonstrate 336-Tbit/s, 332-km real-time transmission of 7×120-channel 75-GHz-spaced DWDM 400-Gbit/s optical signals using 7-core fibre and silicon photonics-based CFP2-DCO module. The spectral efficiency of 37.3 bit/s/Hz is achieved.
