Fault management and control system and method for optical fiber communication network

Abstract

The invention relates to a fault management and control system of an optical fiber communication network, which is arranged in each transformer substation, and comprises a fault detection device whichis connected with a fault identification device, arranged at a port of the optical fiber communication network and used for detecting whether the optical fiber communication network has a fault or not; a fault identification device which is used for distinguishing fault types of the optical fiber communication network and is connected with the fault positioning device, and the fault types comprise link faults and equipment faults; a fault positioning device which is used for determining the position of a fault area; and a fault clearing device which is respectively connected with the fault identification device and the fault positioning device and is used for pausing the work of the fault area or equipment. According to the method, the fault of the optical fiber communication network canbe accurately identified as an equipment fault or a link fault, corresponding measures are taken for different fault types, the troubleshooting time of the optical fiber communication network is saved, a fault point can be accurately found, and large-area or long-time abnormal work caused by the fault is avoided.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a fault management and control system and method for an optical fiber communication network. Background technique [0002] At present, optical fiber transceivers are often used in optical fiber communication network systems for transmission. Optical fiber transceivers have optical fiber receiving ports and optical fiber sending ports. When the optical fiber communication network fails, the port switch is cut off through the main control chip to stop the work of the optical fiber communication network. However, it is not possible to determine whether it is the fault of the substation equipment of the optical fiber communication network or the link failure of the optical fiber communication network. If the port switch is cut off arbitrarily, the staff still has to go to the site to troubleshoot, which takes a lot of time and seriously affects the data of the opti...
