Cisco Optical Channel Interface Controller Pre FECBER Mantissa

1.3.6.1.4.1.9.9.639.1.1.1.1.10

This object gives the mantissa part of the Pre FEC BER or correctable BER at any instance of time. It is represented in one hundreths of a unit.The exponent part is defined in coiIfControllerPreFECBERExponent Pre FEC BER is the BER of the signal before it undergoes the FEC algorithm. FEC will correct errors upto a certain Pre FEC BER beyond which the signal starts becoming uncorrectable. Knowing the Pre FEC BER helps monitor system health. Pre FEC BER is expressed in Scientific E notation with two decimal places Example: The value 235 represents the mantissa of 2.35
