Key Points

A power gain of up to 1.75 dB was achieved over traditional BCH-BCH product codes.
The hybrid soft- and hard-decision decoder was used for the first time in a coherent passive optical network.
The system utilizes flexible-rate Polar-BCH product codes operating with 16QAM modulation.
Experiments demonstrated the performance over 48 km of transmission distance.

Implication

Experimental demonstration shows a power gain of up to 1.75 dB in flexible-rate systems using a new decoder.

Abstract

The flexible-rate Polar-BCH product codes are experimentally demonstrated in a coherent passive optical network system with 16QAM for the first time. Using a new hybrid soft- and hard-decision decoder, we achieve a power gain of upto 1.75 dB over traditional BCH-BCH product codes after 48 km transmission.
