Title: Production of porous optical fiber preform
Inventor: KOMURA YUKIO
IPC: C03B37/07
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a porous optical fiber preform without necessitating the wait time of a burner. SOLUTION: A porous optical fiber preform is formed by traversing plural burners 6a to 6c from a side of a target toward the other side at low speeds Va1, Vb1, Vc1 while keeping prescribed spaces between the adjacent burners and depositing glass soot formed in the flame of the tip of each burner on the outer circumference of a target during the above motion. Each time each burner reaches the other side of the target, the burner is returned to the starting side of the target at a high speed Va1, Vb1, Vc1 corresponding to 1.5 times as fast as the low speed Va1, Vb1, Vc1. The speeds Vb1, Vc1 of the burners 6b,6c following the top burner 6a returning from the other side to the starting side of the target are slowed down so as to enable the restarting of the following burners 6b, 6c without necessitating waiting time after returning to the starting side of the target.
