coiIfControllerQFactor

Module: CISCO-OTN-IF-MIB

OID (symbolic): CISCO-OTN-IF-MIB::coiIfControllerQFactor

OID (numeric): 1.3.6.1.4.1.9.9.639.1.1.1.1.12

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: This Object gives the value of Q-Factor represented in one hundredths of a dB. Q-Factor represents the analog signal to noise ratio. It suggests the minimum correctable BER for a given signal. The higher the Q-factor, the better. Q-factor is expressed in dB

Example: The value 365 represents a Q-Factor of 3.65 dB

What is coiIfControllerQFactor?

Reports the optical signal-to-noise ratio metric known as Q-Factor, in hundredths of a dB, where a higher value indicates a lower minimum correctable bit error rate and better signal quality.
