High-Speed Multilevel Coded Modulation and Soft Performance Monitoring in Optical Communications

We implemented and evaluated probabilistically-shaped multilevel coded modulation and soft-information based performance monitoring at throughputs from 200 Gb/s to 1.2 Tb/s for multi-haul fiber-optic communications. Error-free operations were observed in 5- to 128-ary modulation formats.
