Research Of Optical Fiber Parameter Measurement Method And Application

This article has studied systemically the optical attenuation, the optical fiber longitudinal characteristic, the cut-off wavelength, the mode field diameter, the polarization crosstalk, the chromatic dispersion and the polarization mode dispersion test method. It introduced the different measuring technique and the principle, hase analyzed the measurement influence factors and proposed the partial optical fiber production process quality control means.This article described the optical fiber attenuation and the longitudinal characteristic main test method: the cut-back method and the backscattering method. It has introduced the optical attenuation the production mechanism as well as the production process to the optical attenuation and the longitudinal characteristic influence factor. It has carried on the analysis in view of each kind of test result by carries on the instruction through the measurement result to the optical fiber production. Finally key research to cut-back method has done the dissect in the scientific research item attempt and the applied research, for the first time used the Fourier infrared spectroscope substitution commonly used monochromator, we set up the test system for infrared optical fiber attenuation and obtain successfully.This article has conducted the thorough research to the single-mode optical fiber cut-off wavelength measurement. Introduced uses transmission power method with the single-mode and the multi-mode optical fiber refer, confirms two test methods through the experiment the uniformity, and to affected the cut-off wavelength the factor to make the experimental analysis, proposed the precision measuring cut-off wavelength condition.The polarization maintaining fiber mode field diameter measuring technique has been studied thoroughly.Through the analysis, the contrast and the inferential reasoning and the experiment, proposed suits the polarization maintaining fiber mode field diameter the measuring technique.The polarization maintaining fiber polarization crosstalk measuring technique was introduced.Some actual problems which this chapter in view of when is voluntarily building polarization crosstalk testing device meets to carry on the multi-analysis, proposed some practical solution.Improved its measurement repeatability.This article introduced the optical fiber chromatic dispersion and the polarization mode chromatic dispersion produces the mechanism and several measuring technique, analyzed has affected the PMD measurement the factor, proposed simulation optical fiber in optical cable condition for measuring the polarization mode chromatic dispersion method.At the end, summarized the entire paper work, proposed to the following work forecast.
