#### FEC is a common hardware feature deployed in a high speed interconnect. Due to the signal integrity issue, date being tarnsfer might have bit(s) corrupted. The FEC will correct the data's corruptiom and increment counters to account for corrected bits (Pre FEC) or uncorrected frame (Post FEC) |

The bit error rate (BER) is the number of bit errors per unit time. The bit error ratio (also BER) is the number of bit errors divided by the total number of transferred bits during a studied time interval. Bit error ratio is a unitless performance measure, often expressed as a percentage.[1]

I think we are calculating bit error ration as a unitless number as we are calculating num error bits / total number tranfered. The calculation is not num error bits/sec
