Evaluation method of optical fiber connection loss by unidirectional measurement of optical fiber cable meter (OTDR)

摘要

The present invention relates to a method of evaluating optical fiber connection loss by an unidirectional measurement of optical fiber gauges (OTDRs), and more particularly, to a method of evaluating a connection loss by correcting intrinsic constants according to structural parameters of two connected optical fibers to measured values in one direction of an OTDR , It is possible to verify the reliability of the connection point by easily evaluating the actual connection loss. Therefore, it is possible to reduce the labor and input equipment by OTDR measurement operation to half, and to shorten the measurement operation time and the connection operation delay time according to the measurement It is possible to greatly reduce the cost of the optical fiber connection test, and it is possible to significantly increase the efficiency of the evaluation method.
