Algorithm for restoring the differential mode delay map from the set of pulse responses at the far end of fiber optic link

In this article the simple fast algorithm for restoring the differential mode delay map by results of measured pulse responses at the far end of a multimode optical link is considered. This algorithm is based on application of the leastsquare method and steepest descent method. The estimation of adequacy of the offered method, which give an idea of its workability in scheduling problems of capabilities of using the fibers of given type with a specific light source on multigigabit data transmission networks, is carried out.
