nbsCohpmThresholdsMaxSOP

Module: NBS-COHERENT-MIB

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

OID (numeric): 1.3.6.1.4.1.629.242.21.1.1.106

Node type: OBJECT-TYPE

Type: Unsigned32

Access: read-write

Description: Persistent. The maximum state of polarization (SOP) threshold. Unit measurement: 1 rad/s

The first time nbsCohpmCurrentMaxSOP meets/exceeds this threshold during a given current interval triggers nbsCohpmTrapsMaxSOP.

The reserved value 0xFFFFFFFF disables notifications for this event.

What is nbsCohpmThresholdsMaxSOP?

nbsCohpmThresholdsMaxSOP is read-write and holds a persistent, administrator-set alarm threshold for the maximum state of polarization (SOP) rate of change on this coherent optical interface, i.e. how fast the signal's polarization is rotating/drifting on the fiber, a proxy for physical fiber disturbance (vibration, bending, temperature swings); not-supported is encoded as 0xFFFFFFFF. Unit measurement: 1 rad/s. The first time nbsCohpmCurrentMaxSOP meets/exceeds this threshold (or, for a Min object, drops below it) during a reporting interval, the device raises the nbsCohpmTrapsMaxSOP notification, so a sysadmin sets this value to the maximum state of polarization level they consider unsafe for this specific link's optics and fiber path.

Examples
