nbsCohpmCurrentMaxCD

Module: NBS-COHERENT-MIB

OID (symbolic): NBS-COHERENT-MIB::nbsCohpmCurrentMaxCD

OID (numeric): 1.3.6.1.4.1.629.242.22.3.1.26

Node type: OBJECT-TYPE

Type: Integer32

Access: read-only

Description: Maximum chromatic dispersion (CD) seen in the current interval. Unit measurement: 1 ps/nm

Not supported value: 0x80000000

What is nbsCohpmCurrentMaxCD?

nbsCohpmCurrentMaxCD is read-only and holds a live statistic for the reporting interval now in progress for the maximum 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 nbsCohpmThresholdsMaxCD alarm setting to see how close the link is running to its configured limit.
