Measurement of ESI parameters for single mode fiber
A simple method for measuring equivalent step index (ESI) parameters of the single mode fiber is presented. ESI parameters are obtained by measuring spot size at certain wavelength and cut-off wavelength; and by measuring spot sized at two different wavelengths. The theory and method of measurement are described and the typical experiment results are given.
