nbsCohpmCurrentAveCD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCohpmCurrentAveCD
OID (numeric): 1.3.6.1.4.1.629.242.22.3.1.20
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Average chromatic dispersion (CD) seen in the current interval. Unit measurement: 1 ps/nm
Not supported value: 0x80000000
What is nbsCohpmCurrentAveCD?
nbsCohpmCurrentAveCD is read-only and holds a live statistic for the reporting interval now in progress for the average chromatic dispersion (CD) on this coherent optical interface, i.e. how much the fiber link has spread out the optical signal in time due to wavelength-dependent propagation delay; not-supported is encoded as 0x80000000. Unit measurement: 1 ps/nm. A sysadmin polls it to watch this metric evolve in real time during the interval still underway, and compares it against the matching nbsCohpmThresholdsAveCD alarm setting to see how close the link is running to its configured limit.
