Abstract
This paper presents a simple method for localization of events on traces of group of optical fibers from the same fiber optic link segment (FOLS) of a fiber-optic transmission line (FOTL). This method is primarily focused on determining the location of the most "problematic" for the automated search events "without reflection," which fit to optic fiber fusion splices with insertion loss significantly less than the standard values and simultaneously related values of backscattering coefficients of fused optical fibers. Proposed solution is based on comparison of tables of events for measured traces with test of condition of check sum of distances to the same event in backward directions relative to optical length of fiber optic link segment and condition of belonging of pair of events on traces of different optical fibers of the same direction to one event. As a result, it is possible to make a conclusion about the presence of this event on all other traces of the group. Further, corresponding corrections are made in tables of traces with missing events.
