Embodiment 1

[0034] Such as figure 1 , 2 shown.

[0035] A kind of EPON multi-level non-uniform optical fiber link fault remote judging and positioning method, such as figure 1 As shown, it includes the following steps:

[0036] Step S101: initializing EPON line optical fiber link data;

[0037] Establish the position and path of the optical fiber link through the nodes (such as the site where the OLT is located, the optical fiber transfer box where the optical splitter and ONU are located, and the ring network cabinet, etc.), improve the waveform of the normal optical fiber link test and the information mapping of the nodes in the line, etc., for Provide a basis for later fault judgment and location.

[0038] Step S102: Filter out the alarm information that may be caused by the failure of the optical fiber link from the original alarm information of the EPON network management system.

[0039] Extract the instant fault information from the northbound interface...

Embodiment 2

[0058] Such as image 3 shown.

[0059] An EPON multi-level non-equally distributed optical fiber link fault remote judging and positioning device, which includes an EPON fault alarm acquisition unit 101, an optical fiber link related fault screening unit 102, an optical fiber link related fault storage unit 103, and an optical fiber link optical time domain A testing unit 104 , an optical fiber link resource information storage unit 105 and an optical fiber link fault display and location unit 106 . The EPON fault alarm acquisition unit 101 directly acquires alarm Trap information and description through the northbound interface of the network management system. The alarm unit can be connected with the EPON network management server in one network or connected with the EPON network management server through port mapping from another network to work. The fiber link-related fault screening unit 102 compares the obtained fault alarm information with the fiber-related fault inf...

Abstract

A remote judge positioning method and a device for EPON ( Ethernet Passive Optical Network) multi-level non-average optical fiber link circuit failures are characterized in that the method comprises the following steps: initializing EPON circuit optical fiber link circuit information; screening warning information that might arouse the optical fiber link circuit failures in EPON network management primordial warning information; utilizing an OTDR (optical time domain reflectometry) testing optical software to discover specific optical fiber link circuit optical fiber breaking point information in the warning information; judging and positioning failure styles: entering an equipment failure style processing flow if the failure style is an equipment failure; entering an optical fiber link circuit failure position positioning display if the failure style is an optical fiber link circuit failure. The device comprises an EPON failure warning acquisition unit, an optical fiber link circuit relevant failure screening unit, an optical fiber link circuit relevant failure memory unit, an optical fiber link circuit optical time-domain testing unit, an optical fiber link circuit resource information memory unit and an optical fiber link circuit failure displaying and positioning unit. The invention has the advantage that the positioning is quick and accurate.

Description

technical field [0001] The invention relates to an optical fiber communication technology, in particular to a power communication fault type and location judgment technology, in particular to an EPON multi-level non-equally divided optical fiber link fault remote judgment and location method and device. Background technique [0002] At present, EPON technology is widely used in the communication access network of State Grid Corporation's intelligent power distribution information system. With the continuous expansion of EPON optical network deployment scale, its network maintenance is becoming increasingly important. Since the distribution communication EPON network is laid along with the distribution lines, it has a wide coverage in urban areas and a large number of optical cables and connectors, which may easily cause signal interruptions caused by municipal construction, vehicle hang-ups, and vandalism. Since the optical fiber link in the EPON system is connected in s...
