First Demonstration of 200G Bi-Direction Self-Coherent PON Based on Pre-Amplified Stokes Vector Direct Detection

We propose bidirectional self-coherent PON (SC-PON) architecture based on preamplified SVDD using semiconductor optical amplifiers (SOA) in the transceiver of ONUs and experimentally demonstrate the first 200 G bidirectional SC-PON. We achieve 30.5 and $31.5-\mathrm{dB}$ power budget for the downstream and upstream transmission over a $20-\mathrm{km}$ SMF respectively.
