摘要： The present invention relates to a multi-mode optical fiber having a structure which can be produced with good stability with a communication bandwidth broader than that in the conventional structures, and in which both GeO2 and chlorine are added to a core thereof, and chlorine is also added to a cladding thereof. The cladding contains chlorine such that the average chlorine concentration therein becomes higher than the average chlorine concentration in the core.
