摘要
The present invention relates to a dispersion controlled optical fiber base material manufacturing method using the dispersion controlled optical fiber base material and the modified chemical vapor deposition, dispersion controlled optical fiber preform manufacturing method disclosed is (a) a negative dispersion value in the torch is moved slowly, the core thus prepared base material a first step of forming comprises etching part; (B) a second step of forming a non-etched portion of the torch is relatively faster than the moving speed of the torch in the first step and provided with the etched portion, and then a positive dispersion value in the core; And (c) it comprises a third step of forming the etched portion and a non-etched portion by periodically repeated for the first stage and second stage periodically repeatedly.
