A fiber optic alarm analysis method, device and system based on SDH equipment

Abstract

The invention discloses an optical fiber alarm analysis method based on SDH equipment. The method comprises the following steps: inputting work order information, and invoking SDH equipment information that is associated with the work order information for caching; if the SDH equipment information reports a fiber core alarm, judging whether an alarmed fiber core is in a fiber core range that is associated with the SDH equipment; if the judgment result is yes, judging whether the alarm time is in an implementation time range of the work order information; if the judgment result is yes, detecting the alarmed SDH equipment, and judging whether the alarm refers to a local equipment failure on this basis; if the judgment result is no, analyzing operating characteristics of the alarmed fiber core; and outputting related operating characteristic analysis results of the fiber core to an integrated monitoring module of a communication operation control system. The invention also discloses an optical fiber alarm analysis device and system based on the SDH equipment, which are used for achieving the above method. According to the invention, a method for identifying and analyzing optical fiber alarms in a manual operation process of the optical fiber cores when the SDH equipment implements the work order in a power communication network is provided.

Description

technical field [0001] The invention relates to the field of optical fiber communication alarms, in particular to an SDH equipment-based optical fiber alarm analysis method, device and system. Background technique [0002] In the maintenance process of the grid communication network, there are scenarios of network maintenance and network adjustment. In this scenario, the optical fiber core in the network may be operated, causing related alarms. In addition, the network itself may also be caused by various faults. alarm. Therefore, it is necessary to use corresponding analysis tools or methods to classify related alarms and improve the efficiency of alarm analysis and network maintenance. [0003] The existing communication alarm analysis technology can analyze the root cause of the alarm and roughly locate the corresponding fault section. For example, if a circuit that passes through multiple optical cables breaks an alarm, the system can roughly locate the relevant area an...

Problems solved by technology

[0003] The existing communication alarm analysis technology can analyze the root cause of the alarm and roughly locate the corresponding fault section. For example, a circuit that passes through multiple optical cables and an interruption alarm occurs. The system can roughly locate the relevant area and section but can only locate To the paragraph, it is impossible to perform more detailed and precise positioning

[0004] For the monitoring of optical fiber, there is now OTDR testing technology for optical cable. This method is costly. Generally, a few cores out of dozens of cores of an optical cable are selected for monitoring, and it is impossible to achieve comprehensive monitoring for each fiber core.
