Abstract
Signal-to-noise ratio (SNR)-based bit error ratio (BER) calculations for reporting beyond a forward error correction (FEC) threshold include measuring signal-to-noise ratio (SNR) of a first signal; extrapolating the SNR of a first signal to determine an SNR of a second signal; and determining a pre-FEC bit error rate (BER) for the second signal based on the determined SNR of the second signal. The process can further include reporting the determined pre-FEC BER. The measuring and extrapolating can be used when the second signal is beyond the FEC threshold.
