摘      要：A simple method to measure the length of optical fiber is proposed using microwave photonic *** length of fiber is measured according to the free spectral range(FSR)of the microwave photonic *** measurement accuracy is only related to the accuracy of FSR *** accuracy is further improved by introducing a reference fiber,and the method was verified in the experiment with 2-10 m single-mode fiber.
