First Real-Time 224Tb/s Single-Span 106-km Field Trial Using Commercial 130-Gbaud DP-QPSK 400Gb/s Backbone OTN Transceivers Over Deployed 7-Core Multi-Core Fiber Cable

We demonstrate the first real-time single-span 106-km field trial over deployed 7-core fiber cable using commercial DP-QPSK 400Gb/s backbone OTN transceivers, which achieve a bit rate of 224Tb/s with a more than 3.5-dB OSNR margin.
