Description: Quality Factor Standard Deviation, Optical Transport Unit.
What is cienaCesPmBasicOtuHistoryBinQStdevOtu?
This reports the standard deviation of the Q-factor samples for this OTU signal within the bin. Because this reading sits in the rolling window of completed 15-minute history bins for this OTU signal, a rising standard deviation on this signal, even with a stable average Q-factor, reveals the link's quality is becoming less consistent -- for example from an intermittent connector or a marginal amplifier -- which the average alone would hide. For example, a Q-factor standard deviation that jumps from 0.2 dB to 1.5 dB on this OTU signal, with the average unchanged, points to intermittent instability worth chasing before it becomes continuous, within that completed 15-minute window.
