Fluctuations in dBm sensor values

Hi,

I've been thinking about this for quite some time. We are monitoring all our SFP core ports in Observium and I can see Fluctuations on TX/RX one some interfaces, its not a lot (0.1db) but one other interfaces its really stable. Seems to be more of an issue on fibers internally (both SM and MM) but not so much on dark fiber exiting the building.

I know interference can be a thing but should it Fluctuate at all?
