Method and system of analyzing optical cable failures

The invention provides a method and a system of analyzing optical cable failures. The method of analyzing the optical cable failures comprises steps as below: obtaining real-time configuration information, alarming information and performance information of equipment; obtaining corresponding relationship of the equipment and pipelines; judging whether alarming information of alarming equipment is information relevant with optical paths. If the alarming information of the alarming equipment is the information relevant with the optical paths, the optical cable failures are analyzed and located by the optical cable failure analyzing rule based on the probability theory computing algorithm, and the analyzing process particularly comprises steps as below: analyzing the middle section of the optical path according to the relevant alarming information of the optical path, then analyzing the interruption of the optical cable section according to analyzing the obtained interrupted optical path. The method and the system of analyzing the optical cable failures achieve fast and accurate locating of optical cable failures, and are capable of effectively saving hardware investing cost of analyzing optical cable failures in an optical time domain reflectometry (OTDR) mode.
