METHOD OF IMPROVING PERFORMANCE OF OPTICAL TIME DOMAIN REFLECTOMETER (OTDR) |
摘要 |
A method of improving the performance of an optical time domain reflectometer (OTDR) is provided. The method according to an embodiment of the present invention can increase accuracy of a distance of the OTDR through an initial calibration method with respect to the refractive index of an optical fiber, and can accurately detect a fault position and accurately analyze a fault cause through a real-time calibration method with respect to the refractive index of the optical fiber when faults and performance degradation occur. |
