Time domain algorithm for calculating spatially measured dispersion in optical fibers

Simple and fast algorithm for calculating spatially fiber chromatic dispersion is discussed. This method is applied on the data collected from measuring the Stokes wave of the back-reflected Rayleigh scattered signal in optical fiber under test. The data analysis is performed in the time domain contrary to already known analysis in frequency domain. The results achieved in the time domain match well with those in the frequency domain.

► Fiber spatial dispersion can be calculated easier and faster in the time domain.
► New algorithm is introduced to analyze data collected for optical fiber under test.
► Results produced in time domain match well with algorithm in the frequency domain.
► Data is analyzed for different kinds and lengths of fiber (NDSF and DSF).
