Description: Attenuation Gradient Threshold on Receive Fiber. Applies to both TRMT and RCV directions; but threshold violation is reported for each direction separately by the 'tapping' alarms: INTRUDE-RCV and INTRUDE-TRMT.
What is scCapAttGradientTh?
This OID sets the sensitivity level for detecting fiber tapping—unauthorized physical access to the fiber link—by monitoring sudden attenuation changes. Network engineers enable this with an appropriate threshold to alert on potential security breaches or someone inserting an unauthorized tap on the fiber. For example, if someone breaks into the fiber at a distribution point and inserts a coupler, the sudden attenuation change triggers an INTRUDE-RCV or INTRUDE-TRMT alarm.
