200-Gb/s, 430-km PDM-DQPSK Trans­mis­si­on with End­less Po­la­ri­za­ti­on Tracking

200-Gb/s, 430-km PDM-DQPSK Transmission with Endless Polarization Tracking
For the first time, an endless optical polarisation tracking speed of 100 krad/s is demonstrated. During a 64-hour measurement, a polarisation trajectory of ...
