Abstract :
We propose and demonstrate a new fiber length measurement method, which supports large absolute length and high accuracy measurement of fiber. This method is based on multi-stage optical fiber delay lines structure and self-calibration method with Precision Reflectometer. The precision maintains 20 µm and the enlarged measurement range reaches to 6395.43mm.
