Abstract: The dispersion shifted single mode optical fiber is manufactured by the stages of preparing a core member consisting of an inner core part made of a germanium-added quartz glass which optionally contains fluorine and an outer core made of a fluorineadded quratz glass having a refractive index smaller than that of the inner core part, making a glass tube made of a fluorine-added quartz galss having a refractive index smaller than that of the outer core part, inserting the core member into the glass tube, heating and fusing them together.
