Description

불소를 클래드부에 함유하는 광파이버용 모재의 제조방법Manufacturing method of base material for optical fiber containing fluorine in clad part

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 대표적인 단일 모우드파이버의 굴절을 분포를 표시한 도면. 제2도는 다공질 유리층 합성장치의 일례를 설명하는 도면. 제3도 및 종래법에 의하여 얻어진 투명유리모재의 굴절을 분포를 표시한 도면.1 is a diagram showing the distribution of the deflection of a representative single mode fiber. 2 is a view for explaining an example of the porous glass layer synthesizing apparatus. Figure 3 shows the distribution of the refraction of the transparent glass base material obtained by the conventional method.
