Application of MIMO concept to detect nonreflecting events on cable fiber traces

The paper presents the research results to assess the efficiency of using MIMO technique in the tasks of detection and location of nonreflecting events on traces of a group of optical fibers of a cable line. The mean values and standard deviations of the detection probability of a splice closure and also the first described efficiency parameters are calculated as evaluation criterion. Calculations are carried out for different values of cable capacity, repeater spacing and dynamic range of reflectometer. The analysis showed that the use of MIMO technique significantly increases the detection probability of a splice closure on traces of optical fibers of a cable line.
