WebDamage threshold determines the power density that a glass fiber can handle, so it must also be considered. Defined by the laser beam wavelength, damage threshold is … WebOct 23, 2015 · There are two thresholds you need to be concerned with. Saturation point (where the receiver is “blinded”, and takes errors). Damage point (where the receiver is actually damaged). The actual values depend on the specific optic. But generally speaking, only 80km+ optics are at risk. phoenix gold titanium series https://billymacgill.com
