Abstract

PURPOSE:To obtain a highly uniformly optical fiber material having the desired distribution of refractive indices at its central portion by spraying gas to the inner wall of a tubular body on which wall wall is deposited optical fiber glass and fusing the body by heating while cooling the glass.
