Fine history alarm record.
Judge the reason of fiber failure occurs and fault location by Optical Time Domain Reflectometer.System integration high-performance
RTU (OTDR) equipment, the test of perfect, convenient optical time domain reflection is provided and is supported；There is provided routine test, call the roll test, obstacle
Three kinds of test methods of alarm test.Routine test：Independent tester is arranged according to needs are safeguarded, to every test fibre core in user
Draw, period unit can from minute to day, the moon, year.After routine test, measured curve and reference curve are automatic in RTU
It is compared, when more than the thresholding of setting, that is, generates warning information.Routine test can be with the transmission matter of long-term follow circuit
Amount, the problems such as capable of finding to deteriorate in time.It calls the roll and tests：According to interim needs, user by set by hand range, pulsewidth,
The parameters such as backscattering coefficient, Optimizing Mode realize monitoring and analysis to target lightguide cable link.Alarm test：RTU is according to next
From the warning information (receiving without optical signal, bit error rate etc.) in SDH network management systems or comprehensive monitoring system, by inquiring built-in library
Table tests relevant optical cable.This alarm test has highest priority level, it will stop ongoing regular
Test or test of calling the roll, complete alarm test, and send test data to central station on immediately with most fast speed.
Spare fibre is detected：All fibre cores in a piece optical cable, whether use, journey affected by environment
Degree is roughly the same with the variation of physical characteristic, such as：Outer force effect, moisture infiltration, circuit make moist or circuit breakdown etc., is showed
The change situation of the performance data gone out is essentially identical.Therefore it can substantially reflect whole optical cable packet by testing standby fine performance
Include the performance of working optical fibre.Or the technology using wavelength-division multiplex, so that test wavelength is combined to together with operation wavelength, shares object
A kind of method for managing medium (optical fiber) to be tested.The advantage of this test method is to be reflected directly in fibre core
Situation, for joint fault, the disconnected fine situation in part can be measured.One point is placed on the optical fiber of bearer service
Light device separates a part of (the 5% of such as general power) to OPM from fiber optic service signal, the small-power light being separated out is monitored by OPM
The situation of change of signal.If OPM monitoring results are abnormal, system if think the corresponding optical cable segment of business optical fiber may occur therefore
Barrier, tests relevant optical cable to start OTDR.By being compared analysis to OTDR test curves, it is possible to find routing
In failure and positioned.Reference information：System stores the OTDR test curves under each routing normal operating conditions,
By the way that current OTDR test curves compare analysis with reference to test curve, operating personnel can quickly determine optic fibre characteristic
Change point, if test data and reference data grave fault, system will send out warning information.All fibres in a piece optical cable
Core whether uses, and the variation of degree affected by environment and physical characteristic is roughly the same, such as：Outer force effect, moisture
Infiltration, circuit are made moist or circuit breakdown etc., and the change situation of the performance data shown is essentially identical.Therefore standby by testing
Fine performance can substantially reflect that whole optical cable includes the performance of working optical fibre.

Center.After administrative center receives test data file, according to the OTDR curve datas and engineering maintenance information of this routing, carry out
Accident analysis calculates the geographical location of fault point and the relative distance with forward and backward " terrestrial reference " automatically：According to the side of pre-selection setting
Formula sends out warning information, automatically records simultaneously display alarm generation time, obstacle handling time, checkout time, alarm grade, alarm
The information such as source and maintenance personnel.
Alarming processing：When alarm occurs, system display alarm information on the screen, on fiber topology figure in different colors
Display alarm grade, and make a sound prompt.In addition, operator on duty can confirm to alarm and alarm clearance operates,
Real time print goes out the reason of object of alarm, the time that event occurs, alarm on printer, confirms the information such as people.Alarm generation,
Acknowledged alarm, alarm clearance data are stored into alarm history database.
Fault location：Repair in order to facilitate maintenance personnel to optical cable, system can be in opening up based on GIS-Geographic Information System
The position and surrounding geographical environment for showing that failure occurs are flutterred on figure.By fault location algorithm, system will highlight aobvious on map
Show the fault point, so as to maintenance personnel's Quick overhaul.
Data query, statistical report form function：Report is that fiber optic cable maintenance manages necessary Working Means, and system can carry
For a set of perfect fiber optic cable maintenance statistical report form.
In administrative center, the software that operating personnel can be provided by system completes input, configuration, modification tested optical fiber, light
The information such as title, the device port of cable, and establish be tested the corresponding optical line in luminous power port by correspondence, setting
The correspondence of each Optical Cable and photoswitch port is input to data in database according to operating personnel, automatic to establish monitoring
