After 400G fiber-optical communication standard is proposed, considerable attention has been paid to the next-generation optical network. In this paper, we propose a zipper encoder architecture with low-overhead memory and optimized BCH encoder. Working at 500MHz, the zipper encoder can achieve throughput of 962Gbps, which meets the requirement of 800G optical communication system. The whole design was implemented with Design Compiler in the TSMC 65nm. Result shows that our design achieves 1.8x/1.7x energy-efficiency and 2.2x/1.2x area-efficiency higher than prior 200G/400G staircase encoders.
