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.
