Abstract
In this paper, a novel method to measure the distributed polarization mode coupling in polarization-maintaining (PM) fibers is introduced. The measurement system is based on white light interference. A super luminescent diode is used as the broadband light source in the system. The whole test system is working on 1300nm wavelength. There are two main parts of the measurement equipment: polarization adjustment and a scanned Michelson interferometer. In order to improve the accuracy, a piezoelectric transducer (PZT) is applied in the scanned Michelson interferometer. The maximum length of tested polarization-maintaining fiber is one kilometer, and the spatial resolution of this method reached 60 mm along the tested PM fiber. The degree of polarization mode coupling that could be detected is —75dB.
