- BER = Bit Error Rate
- FEC = Forward Error Correction

- throwaway_pdp09 6y agoFor them like me who don't know https://en.wikipedia.org/wiki/Forward_error_correction https://en.wikipedia.org/wiki/Forward_error_correction as I didn't know what the 'forward' part meant. It seems be error correction add to the sending stream to 'mend' broken data, vs error correction by the receiver detecting an error and requesting a re-send.
- henrikeh 6y agoAnd just to elaborate a bit further: Forward error correction is the coding (as in information coding) principle of how to enable error correction. The error correction still happens at the receiving end and it is aided by the redundancy introduced by FEC.
