title: Bandwidth estimation of multispliced GRIN fibers.
abstract: In designing long-haul optical transmission systems, it is important to estimate the characteristics of multispliced long-distance fibers based on data from individual fiber units. In the case of graded-index fibers, however, the mechanism of modal dispersion is complicated and therefore the derivation of an available bandwidth prediction method is difficult. This paper proposes a method based on the wavelength dependence of bandwidths of individual fibers, which is expressed by three parameters: maximum bandwidth B(max); optimum wavelength lambda(opt); and the coefficient of wavelength dependence k. Transmission characteristics of the fiber bandwidth resulting from splicing are theoretically and experimentally discussed.
