Description
Technical field
The present invention relates to the optical communication field, relate in particular to optical link test and optical-fiber network topology method of testing and system.
Background technology
Under the promotion of " broadband China " strategy, each large operator launches keen competition with regard to the FTTH Large scale construction, and along with the large scale deployment of operator on FTTH, the O﹠M cost problem also begins to highlight.For example, in the operation of FTTH, maintenance, management, ONU on-site maintenance difficulty, abominable, the traditional access device of fixing link are disposed also to need to enter the station for three times and just can be finished.
Simultaneously, the FTTH first stage of construction also will face the challenge of service fulfillment, and a plurality of links of activation of service need manual construction, and the cycle is long, client perception is poor so that open.In addition, on the troubleshooting link, its failure rate and Shen announcement rate all are more than the twice of DSL, and regional center processing proportion is high, rate is high to the doorstep.
For guaranteeing that FTTH disposes quality, just must test it, traditional method of testing is light loss tester and OTDR.Wherein light loss tester method then needs two technical staff, and wherein one must have certain experience, can identify the potential problems on the link, if the problem of detecting must send a more experienced technical staff to locate and repair fault; And the method for testing of OTDR then must have the technical staff of expert's level could accurately finish all test assignments; And at present, most fiber deployment company is all keeping the rate of giving an encore up to 5-10%.Cause the reason of giving an encore to be generally: the technical staff lacks the passing through of training, mistake/ understand (bad welding igniting connector) by criterion, incorrect use equipment, the diagnosis of mistake, incorrect OTDR curve, opens failure diagnosis etc.Return to each time on-the-spot expense and all be one and repeat spending, and it has seriously taken the veteran technical staff's of operator time, they can't have been sent to more complicated post and task.An elementary skill personnel's wage is experienced employee's about 50% in general, if operator can send the elementary skill personnel to go to give an encore even carry out the deployment phase test, singly surpasses 50% spending under just can saving aspect the manpower.This is the difficult problem that needs crack really for operator.
In sum, for the PON network test, the incompetent reason of general technology employee is that traditional OTDR too complexity---repeatedly test by the pulsewidth that needs the tester to choose different length, and the OTDR curve under the distinct pulse widths is carried out the analysis of expert's level, at last comprehensively repeatedly the OTDR calibration curve information just can provide complete test report.
Summary of the invention
For solving the problem and blemish of above-mentioned middle existence, the present invention can reduce the number of times at the scene of returning to veritably from the source, can can be drawn by elementary field technician's operation the test result of specialty, and can eliminate most profiling error, thereby help operator to capture number of times and this difficult problem of reducing expenses that reduces the scene of returning to.The present invention adopts many pulsewidths, intelligence link measuring technology, do not need manual intervention, can the Lookup protocol parameter, only need once test just can obtain the test result of expert's level, another large advantage is to need not the manual analysis curve, but with the form of chain graph test result is presented to the user intuitively, this has eliminated the risk of artificial erroneous judgement.Described technical scheme is as follows:
A kind of Intelligent Optical Network topology method of testing comprises:
Optical link is tested, detected linkage length, loss and return loss information, utilize a plurality of pulsewidth combinations that link is tested according to detected information, and a plurality of pulsewidth results after the test are merged;
A plurality of pulsewidth results of test are carried out analyzing and testing, draw the optical-fiber network topology diagram;
Network topological diagram is shown with graphics mode intuitively.
