Description: Optical Power Received (in dBm) for the physical layer. This is applicable only if the media type for the Access Port is fiber.
What is cmEthernetAccPortStatsOPR?
This metric reports the optical power received (in decibels relative to 1 milliwatt) on a fiber-based Ethernet access port, indicating the signal strength of incoming light on the optical interface. Network operators use this to monitor fiber link health and diagnose signal quality issues; weak optical power may indicate dirty connectors, faulty transceivers, or excessive attenuation. This value is only applicable to fiber media ports.
