- 동심 다중관 구조를 가지고, 중심의 유리 원료 가스 분출 포트의 외측에, 당해 유리 원료 가스 분출 포트에 대해서 동심원상으로 1열 또는 복수열 배치되고, 동일 열에 배치된 분출 포트가 동일한 초점 거리를 가지는, 복수의 소구경 조연성 가스를 내포하는 가연성 가스 분출 포트를 가지는 버너를 이용하여, 유리 원료 가스를 화염 중에서 가수분해시켜 생성되는 유리 미립자를 출발 부재 상에 퇴적시켜 광섬유용 모재를 제조하는데 즈음하여, 상기 복수의 소구경 조연성 가스 분출 포트의 초점 거리를 L1으로 하고, 당해 소구경 조연성 가스 분출 포트의 선단으로부터 유리 미립자 퇴적면까지의 거리를 L2로 할 때, 퇴적 초기에는 L1>L2로 하고, 퇴적 도중에 L1<L2로 되도록, L2를 크게 해 가는 것을 특징으로 하는 광섬유용 모재의 제조 방법.
- 제1항에 있어서,퇴적량이 증가하고, 모재의 외경이 증대함에 따라, 상기 버너를 퇴적면으로부터 떼어 놓고, 거리 L2를 크게 해 감으로써 L1<L2로 하는 것을 특징으로 하는 광섬유용 모재의 제조 방법.
