LUT-Assisted Clock Data Recovery and Equalization for Burst-Mode 50-100 Gbit/s Bandwidth-Limited Flexible PON

We demonstrated LUT-assisted CDR and equalization for burst-mode 50-100 Gbit/s bandwidth-limited PON, achieving signal recovery under large 100 ppm frequency offsets and 0.5 UI phase mismatch using reduced 50ns preambles, with 0.3dB sensitivity penalty only.
