FEC – SDFEC2 vs SDFEC

FEC-SDFEC2 vs SDFEC
Both FEC soft-decision FEC-2 ‘SDFEC2’ and soft-decision FEC ‘SDFEC’
Hard-decision FEC is ‘HFEC’ schemes
FEC Functions OTU, tributary boards,line boards, and have forward error correction ‘FEC’ function.
The FEC, HFEC, SDFEC, SDFEC2, AFEC and AFEC2 reduce the bit error rate ‘BER’ during OSN transmission, and enhances the quality of the transmission signal of the DWDM network
The High-Performance-Forward-Error-Correction ‘HFEC’ function and the Soft-Decision-Forward-Error-Correction ‘SDFEC’ and ‘SDFEC2″ and Advanced- Forward-Error-Correction ‘AFEC’ function, and AFEC2 function.
FEC, HFEC, SDFEC, SDFEC2, AFEC and AFEC2 OSN System requirements are at the receiving end, extending the transmission distance between the optical amplifier section and the re-generator section.
