What is osnrInstant?
This is the instantaneous, most-recently-sampled value of the optical signal-to-noise ratio (OSNR) measured on this channel during the current performance-monitoring interval, expressed in dB. A live OSNR reading is one of the first values an admin checks when a channel's error rate suddenly rises, since a falling OSNR directly explains degraded signal quality. For example, if an amplifier along the path starts to fail, an admin would see osnrInstant drop in real time on every downstream channel riding that amplifier.
