CONSTITUTION: An optical fiber for dispersion control (300) comprises a core layer(310) composed of silica, germanium oxides and phosphorus oxides, and a clad layer(320) composed of silica, germanium oxides, phosphorus oxides and Freon. A coating layer(330) is disposed on the periphery of the clad. The silica is a main component of the core and the clad, the germanium oxides is added for adjusting the refraction dispersion, the phosphorus oxides is added for reducing the viscosity difference, and the Freon is added for lowering the refraction. The clad layer is deposited on the inner surface of a deposition tube, and the core layer is deposited on the inner surface of the clad layer. A hollow section remaining in the center of the core layer is filled by heating the deposition tube along the axial direction thereof using a burner. It is possible to achieve the uniform optical property by minimizing the variation of the optical property even when a drawing temperature is increased for drawing the optical fiber for dispersion control from the large size preform. Also, it is possible to lower the core deposition temperature, and to reduce the concentration time.
