The auto-measuring system of optional fiber polarization characteristics is studied. This paper describes the characteristics and parameters of PM optical fiber and also analyze the modulate characteristics of photo-electricity signal as well as effective method of weak signals. It gives an auto-measuring method of PM optical fiber based on FPGA technology and also gives comprehensive details of designing and implement. Based on the above works, we make it a usable and reliable auto-measuring system. The using of instrument validates the effectiveness of the scheme and designing.
