Continuous real-time measurements are demonstrated from a 200Gb/s format configurable CFP transceiver that uses dual-polarization probabilistic-shaped 16QAM (DP-PS16QAM) modulation. Placed in a 50GHz coherent DWDM transmission system, DP-PS16QAM achieves a back-to-back 1.8dB OSNR gain over uniform DP-16QAM. It also transports over 1940km with EDFA-only amplification, thus doubling propagation distance of uniform DP-16QAM. Furthermore, a 1Tb/s super-channel consisting of five 200Gb/s DP-PS16QAM sub-carriers is placed in a 200GHz grid, and it achieves over 1600km transmission and 5b/s/Hz SE with a raw SE at 6.86b/s/Hz.
