Abstract :
An equivalent step-index-fiber method (ESFM) has been extended to multicladding fibers. Upon defining the refractive-index profile for the multicladding preform, the transmission parameters, especially the cutoff wavelength of the fiber drawn from the preform, can be predicted directly before fiber-drawing, saving time and energy. Comparison between the theory and results from experimental fibers shows an accuracy of 5% in predicted cutoff wavelengths
