Abstract

We demonstrate the world's first field-trial of bidirectional 200G TFDM coherent PON enabled by real-time FPGA-based reception with two subcarriers, achieving - 34-dBm downstream sensitivity and - 31-dBm upstream sensitivity at 4.5-dB subcarriers power-difference with 21-dB dynamic range.
