WebMar 15, 2024 · It is called forward error correction (FEC), a technique has been used for years to enable efficient, high-quality data communication over noisy channels. Today, with the increase of data transmission capacity and extension of distance, let’s learn more about FEC technique in optical networks. What Is FEC? WebMar 19, 2024 · Normally, problems with excessive bit/word errors are not an ASIC problem. However, if you want to move the cables around to different ports on the same module then you need to know the archetecture of the module (port layport per ASIC). For Example: MDS 9500 (DS-X9248-256K9) has 4 FC ASICs called Thunderbirds. These FC ASICs each …

Weba Reed-Solomon based FEC acting on a 514 symbol codeword with each symbol consisting of 10 bits, expanded to 544 symbols with the addition of FEC coding. This allows the code to detect and correct up to 16 errored symbols in each codeword block (the FEC can detect but not correct more than 16 errored symbols and can flag the codeword as corrupted).

Webuncorrected errors at the FEC output is not that errors appear at the MAC/PLS service interface, it is that frames are discarded. However, this is also true for 64B/66B coded Ethernet systems without FEC. Here, nearly all errored frames contain 3 or less errors and are guaranteed to be discarded by the MAC because the CRC does not match the data.
