How to Eliminate the Unreal Peak?

Unreal peak is mainly along the fiber by Fresnel reflex peak returned in two events between multiple reflection results, and therefore must be reduced from the peaks of amplitude。When we const it, we should choose return loss greater activity connector or in the optical fiber cable port place and matching liquid.

If it is due to the end of the fiber formation of unreal peaks, the fiber end in the optical fiber matching liquid, or fiber end play a small diameter knot, or range as far as possible is set to a little more than be measured the length of the fiber

If magic peak appeared in the effective backscattering curve, then change measuring engineering method, Such as access another section lead fiber using ratio measuring shoe line longer guide optical fiber or from the other end of the optical fiber measurement, magic peak may no longer appear.
