摘要
The present application provides an optical fiber testing method based on an optical time-domain reflectometer, and an optical time-domain reflectometer, said method comprising: an optical time-domain reflectometer emitting a plurality of pulsed lasers within a preset testing time, the test range corresponding to each of the pulsed lasers being greater than or equal to the preset testing length in the optical fiber to be tested which is connected to the optical time-domain reflectometer, the test range corresponding to each pulsed laser being different; using each pulsed laser to generate corresponding sub-test data; calculating the average value of the sub-test data to obtain a test result. Hence, if the test range is less than the length of the optical fiber to be tested, then the plurality of pulsed lasers having different test ranges are used to test an optical fiber having a preset test length, and it is possible to effectively eliminate the effects of ghosting, making the test results more accurate.
