2023年11月20日 · 800G以太网是一种高速以太网技术，用于数据传输和通信网络，提供了每秒800千兆比特（800Gbps）的数据传输速率。 800G以太网的速度比前一代400G以太网快一倍，提供了更大的带宽，适用于处理大规模数据传输、高清视频、云计算、物联网等高带宽需求。

FEC requirements for 800GbE/1.6TbE optics (200G per lane) are elaborated in terms of performance, latency and power.

In this presentation, we share observation of FEC related topic of logic layer to help move forward. “In telecommunication, information theory, and coding theory, forward error correction (FEC) or channel coding is a technique used for controlling errors in data transmission over unreliable or noisy communication channels.

2024年4月25日 · FEC（Forward Error Correction）被廣泛運用，起因來自 400GbE／800GbE、及未來 1.6TbE 等更高速的乙太網路速率皆使用 PAM-4 訊號調變。 這種調變格式讓 400GbE 及以上速度運行得以實現，但 PAM-4 調變因為是在每個符號（symbol）上編碼 2 個位元，讓時脈速率不變並把資料速率變成 2 倍，雖然快，卻更容易受到雜訊和訊號完整性的影響；然而，透過使用整合到乙太網路堆疊中的前向糾錯（FEC）編碼，可以緩解這一問題。

Abstract: Forward error correction (FEC) performance down to 1e-15 bit error rate (BER) of a open FEC code (OFEC), which was recently proposed for the 800G inter-data center interconnect (DCI) standard, is verified with a 100-piece-FPGA implementation at a …

With a record 400Gbps 100-piece-FPGA implementation, we investigate performance of the potential FEC schemes for OIF-800GZR. By comparing the power dissipation and correction threshold at 10 −15 BER, we proposed the simplified OFEC for the 800G-ZR FEC.

Propose FEC architecture to support 100G/lane and 200G/lane 800GE PHYs applications and migration. End-to-End FEC architecture is the best for Gen1 and Gen2 interconnects (performance discussion can refer to lu_3df_01b_220215.pdf). While for Gen1.5, a segmented FEC architecture with terminated FEC for 200G/L optics is preferred.
