High-Performance 50G-PON Burst-Mode Upstream Transmission at 25 Gb/s with DSP-Assisted Fast Burst Synchronization and Recovery

We experimentally demonstrate high-performance burst-mode upstream transmission at 25 Gb/s for 50G-PON. With a novel DSP-assisted burst-mode receiver, we achieve fast burst synchronization and recovery within ∼200 ns, and a record receiver sensitivity of −29.8 dBm at the SD-LDPC BER threshold of 2×10−2 after 20-km SSMF transmission.
