An optical cable fault location method and device

The present invention discloses a method and apparatus for locating a cable fault, wherein the method comprises: receiving the test results are transmitted in an OTDR monitor cable; calculating a test result based on the length of the cable fault point occurs; optical cable according to a preset resource locating the fiber optic data model point of failure. The present invention is insufficient to make up for deficiencies affect existing cable resources fast cable fault location algorithm to improve the practicality of cable locating algorithm technology, while addressing the problem of convergence technology resource model and core monitoring data exchange, enables the user to this method is rapid fault location.
