  2. 제1항에 있어서, 가열로의 온도가 500∼1500℃인것을 특징으로 하는 광파이버의 선뽑기방법.
  3. 제1항에 있어서, 가열로에 넣기 직전의 광파이버의 온도가 500∼1500℃것을 특징으로 하는 광파이버의 선뽑기방법.
  4. 제1항에 있어서, 가열로내에서의 광파이버의 잔류시간이 0.1∼10초인것을 특징으로 하는 광파이버의 선뽑기방법.
  5. 제1항에 있어서, 상기 가열로의 갯수는 적어도 하나이며, 복수개의 가열로를 설치한 경우에는 각 가열로의 온도를 독립적으로 제어할 수 있도록 한 것을 특징으로 하는 광파이버의 선뽑기방법.
  6. 제1항에 있어서, 노심관은 석영, 고순도 카아본, 열분해성 흑연이 피복된 카아본 및 Sic가 피복된 고순도 카아본으로 구성된 재료로 이루어진 것을 특징으로 하는 광파이버의 선뽑기방법.
