PROBLEM TO BE SOLVED: To provide an multimode dispersion compensating fiber that is very wide in a wavelength region intended for a high transmission bandwidth and that is suitable for wavelength multiplexing, and also to provide a mode dispersion compensating method, an optical waveguide, an optical transmission line and an optical communication system using this fiber.;SOLUTION: When connected to a fiber to be compensated, i.e., a fiber composed of a Ge added multimode fiber which is optimized in the 1.3 μm wavelength band to have a maximum transmission bandwidth in the wavelength and which is prepared by adding Ge to fused quartz as dopant, the multimode dispersion compensating fiber (MM-DCF) has a characteristic in that it compensates mode dispersion in a manner that the transmission bandwidth becomes higher in the wavelength or the wavelength band other than the 1.3 μm band. The optical waveguide 10 is constituted by connecting the fiber 12 to be compensated and an F added MM-DCF 11.;COPYRIGHT: (C)2006,JPO&NCIPI
