Abstract

Profile dispersion affects the bandwidth of graded-index multimode fibers. In this paper, two graded-index multimode fibers of nearly 2-km length, of different index profile, and the combined fiber obtained by splicing them are examined by the swept-frequency method. It was confirmed that the spliced fiber also has a wavelength-dependent characteristic, and that the interfiber compensation of the intermodal dispersion actually occurs in the wavelength region between the optimum wavelengths at which the individual fibers have maximum bandwidths. Moreover, transverse displacement of the fibers in the splice was found to have a wavelength-dependent effect on the bandwidth.
