Abstract
A dispersion control fiber and a method of manufacturing a large size preform. The dispersion control fiber includes a core composed of SiO , GeO , and P O , and a cladding composed of SiO , GeO , P O , and Freon. The P O content is selected not to exceed 10% total weight of a compound composing the core. The method of manufacturing a large size perform for a dispersion control fiber by an MCVD process includes depositing SiO , GeO , P O , and Freon in an inner periphery of a deposition tube to form a cladding layer, and depositing SiO , GeO , and P O on an inner periphery of the cladding layer to form a core layer.
