Description: Quality Factor Standard Deviation, Optical Transport Unit.
What is cienaCesPmBasicOtuHist24HBinQStdevOtu?
This reports the standard deviation of the Q-factor samples for this OTU signal within the bin. Because this reading comes from a closed, completed 24-hour history bin 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, across that completed 24-hour day.
