DISPERSION SHIFTED OPTICAL FIBER.

Abstract TITLE: DISPERSION SHIFTED OPTICAL FIBER. A dispersion shift optical fiber which comprises a core provided with a center core portion and a peripheral core portion formed around the center core portion and a clad formed around the core and have a refractive index distribution shape in which the refractive index of the peripheral core portion is higher than that of the center core portion and the refractive index of the clad is lower than that of the peripheral core portion, wherein by properly determining the structure parameter the condition that the optical fiber is a single-mode optical fiber and the bending loss is 100 dB/m or less is satisfied, the effective core area is sufficiently increased, and the dispersion slope is decreased (FIG.)1
