Abstract

We conduct field trials to confirm that advanced digital coherent technologies can be employed to double the performance of 400-Gbps optical transmission compared to conventional technologies. Additionally, we show that 400-Gbps channel transmission does not affect existing 100-Gbps channels. We employ these technologies to realize a world-beating result in terms of long-haul transmission: 400-Gbps over 1900 km.
