Method used to determine whether the corrected error count is proper

Question:
A huge corrected error count commonly exists on OTU boards with FEC. How do I determine whether the number is proper?
None
Analysis:
The corrected error count is associated with bit error rate.
Bit error rate = Corrected error count/(Time x Board rate).
Answer:
The corrected error count is expressed in bits, and the board rate is expressed in bit/s. Therefore, the time must be converted into seconds. For example, the rate of an LWF board is 10 Gbit/s. If the 24-hour corrected error count is 5 million, the BER is calculated as follows: (500 x 10000)/(24 x 3600 x 10 x 1000000000) = 5.79 x 10E�?. Then, you can determine whether the corrected error count is proper.
