2023年1月13日 · FEC（前向纠错码）是用于控制数据传输中误码率的技术，尤其在高速光通信中，能检测和纠正错误，提高传输质量和距离。 Reed-Solomon码是常用的FEC类型，适用于不同类型的光模块，如25G和100G模块。 FEC有块码和卷积码两种形式，能有效对抗噪声和光色散导致的信号退化，但也引入了延迟和额外开销。 在实施FEC时，需确保链路两端匹配的FEC类型。 光模块 正在向着高速率、远距离方向发展。 与100G以太网及更高速率的高速通信时，可能会出 …

2022年12月23日 · 具备fec 符号错误纠正功能，具有误码符号分布图，支持fec-kr4和fec-kp4; 在软件界面上可以快速设置fec模式，显示纠错前的误码个数和误码率、纠错后的误码个数和误码率，纠正的误码个数。

FEC encoding protects IP packets against errors caused by noise and other impairments, and is able to detect and correct those errors. However, the more capable a particular FEC encoding scheme is at detecting and fixing errors, the more latency it adds into the network.

A PROPOSED FEC STRUCTURE • A multi-mode FEC structure based on distributed MLC concept. • The MLC encoding process is done in 2 separate locations. • Code-1 can select KR4 FEC or any other light FEC. • Code-2 uses a strong FEC. It can also be an umbrella code consisting of mother code and daughter code. • Ex-1: Code-1 uses KR4 FEC, m ...
