Determining The Zero Dispersion Wavelength and Dispersion Slope of Fibers Used for the Fiber Distributed Data Interface (FDDI) (NOT KNOWN IF PUBLISHED BECAUSE AUTHOR HAS LEFT AT&T)

Theoretical relations are obtained for graded-index multimode fibers that relate zero dispersion wavelength (lambda sub 0) to normalized refractive index difference (delta) and dispersion slope (S sub 0) at lambda sub 0 to lambda sub 0. Comparison of these curves with empirical data shows good agreement between lambda sub 0 and delta, but large scatter in S sub 0.
