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
