Computing Insertion Loss when Transitioning Through Dissimilar Fiber
Discusses steps for calculating IL when measuring through dissimilar fiber
When trying to make an insertion loss measurement in dissimilar fiber (e.g. SMF-to-Low Bend Loss to-SMF), the calculation is complicated by the fact that the Raleigh scatter level is generally different, and the shift in scatter level must be accounted for to produce an accurate result. To properly measure insertion loss we need to know the relative difference in scatter levels.
