nbsCoherentStatsMinDGD
Module: NBS-COHERENT-MIB
OID (symbolic): NBS-COHERENT-MIB::nbsCoherentStatsMinDGD
OID (numeric): 1.3.6.1.4.1.629.242.90.2.1.33
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: Minimum differential group delay (DGD) observed. Unit measurement: 1 ps
Not supported value: 0xFFFFFFFF
What is nbsCoherentStatsMinDGD?
nbsCoherentStatsMinDGD is read-only and holds the minimum differential group delay (DGD) observed on this coherent optical interface since statistics collection last started or was cleared (nbsCoherentStatsState), i.e. how much delay skew polarization-mode dispersion has introduced between the two polarization axes of the signal; not-supported is encoded as 0xFFFFFFFF. Unit measurement: 1 ps. A sysadmin treats it as a longer-run baseline for this specific optic/fiber path, useful for spotting a slow drift in link quality that a single quarterHour or twentyfourHour sample in nbsCohpmCurrentTable might not reveal.
