Fault section positioning method and system of optical access network

Abstract

The invention relates to a fault section positioning method and system of an optical access network. The method comprises the following steps: acquiring a network element alarm; if acquiring an ONU (optical network unit) power-down alarm, acquiring equipment resource of the alarming ONU, detecting whether the alarming ONU is a MDU (multiple dwelling unit) according to the equipment resource, if the alarming ONU is the MDU, determining that the MDU is the power-down fault; if acquiring any one or more of a PON (passive optical network) port R-LOS alarm, an ONU offline alarm, an ONU optical access bad signal quality alarm and an ONU webmaster off-net alarm, acquiring valid ONU, and judging whether the acquired alarm is the power-down fault and determining the primary fault section according to the state of the valid ONU, and determining the final fault section according to the judgment result of the power-down fault and the primary fault section. Through the adoption of the method and system provided by the invention, the fault of a passive facility of the optical access network can be precisely monitored, the end-to-end accurate positioning of the fault of the optical access network is really realized, and the coverage range of each of the pre-checking and pre-maintenance is effectively enlarged.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for locating a faulty section of an optical access network and a system for locating a faulty section of an optical access network. Background technique [0002] With the advent of the Internet era, user communication needs and industry development have undergone profound changes, which has brought great challenges to the operation of the traditional telecom industry. The traditional copper broadband network is limited by the lack of network equipment and information system capabilities, and it is difficult to achieve comprehensive quality monitoring coverage including user modems (modems) and lines. Troubleshooting is mainly based on passively responding to customer declarations and maintenance, and the means are single and inefficient. high. Facing broadband products, users and networks in the optical Internet era, the operation and maintenance system must not ...

AI Technical Summary

Problems solved by technology

For ODN (Optical Distribution Network, optical distribution network) faults in the network composed of passive devices and lines, there is still a lack of effective means to analyze and locate them

Due to the lack of effective monitoring of passive facilities, on the one hand, it affects the wider promotion of optical access network fault pre-check and pre-repair, and restricts the Internet transformation of network operation; During the failure process, maintenance personnel need to test and analyze one by one among many jumping points, which will consume a lot of manpower cost and time cost
