Chromatic Dispersion Measurements of Single-Mode Fibers, Polarization-Maintaining Fibers, and Few-Mode Fibers Using a Frequency Domain Method

Chromatic dispersion is an important fiber attribute affecting transmission performance over optical fibers. Various chromatic measurement methods have been developed primarily for single-mode In the literature, techniques were also to characterize few-mode fibers and multi-mode These are often subject some limitations. this paper, a simple robust method of fibers, polarization--maintaining presented using frequency domain instrument vector network analyzer. The applied all three types through one methodology uniformly. Using analyzer, obtains complex transfer function transmission. inverse Fourier transform measured used determine group delays each mode fiber. Although sampling highly under-sampled whole link, proper treatment data, we can de-alias signals obtain accurate values mode. By measuring different wavelengths, data yield wavelength window.
