Operator Trial of 100 Gbit/s FLCS-PON Prototype with Probabilistic Shaping and Soft-Input FEC

We introduce probabilistic shaping and soft-input FEC to our 100-Gbit/s flexible PON concept, FLCS-PON, beside varying the modulation format and FEC code shortening/puncturing. These features improve granularity of bitrate adjustment for various channel conditions in downstream direction. We demonstrate our prototype in an operator trial.
