Field Trial of Probabilistic-Shaping-Programmable Real-Time 200-Gb/s Coherent Transceivers in an Intelligent Core Optical Network

We report the first demonstration of the use of probabilistic-shaping-programmable real-time 200-Gb/s coherent transceivers in a deploying intelligent core network to achieve improved performance, energy-efficiency, and protection in case of fiber cuts, showing the benefits of such probabilistic-shaping-programmable transceivers.
