FEC Function Certain OTUs, tributary boards, and line boards have forward error correction (FEC) function, the high performance forward error correction (HFEC) function, the soft-decision forward error correction (SDFEC) function, SDFEC2, the advanced forward error correction (AFEC) function and AFEC-2 function. With the FEC, HFEC, SDFEC, SDFEC2, AFEC and AFEC-2 functions, the OSNR requirements of the system are less at the receive end. This extends the transmission distance between the optical amplifier section and the regenerator section. In addition, the FEC, HFEC, SDFEC, SDFEC2, AFEC and AFEC-2 help to reduce the bit error rate (BER) during the transmission. It also enhances the transmission quality of DWDM networks.

Which FEC is applied when and where, I mean the situation or the condition of transmission. Could you please describe?

Thank you.

In what situation shall we need to choose HFEC complaint compared to FEC?

Hi there！
Forward Error Correction (FEC), also called Forward Error Correction (FEC), is a method to increase the reliability of data communication. In a one-way communication channel, once an error is detected, its receiver has no right to request transmission. FEC is a method of transmitting redundant information using data. If an error occurs during transmission, the receiver will be allowed to re-establish the data.

I'll be posting a post on how FEC works next month, please follow me.
