摘要： A glass rod (2) for a core or for the core and a cladding is inserted into a glass pipe (1) for the cladding and heated by a heater (3) while the pressure inside the glass pipe (1) is reduced.
The feed rate V R of the glass rod is adjusted such that it is faster than the feed rate V P of the glass pipe and not more than twice the feed rate of the pipe; both being fed into a heating furnace where the rod and pipe are integrated and elongated.

摘要： A glass rod (2) for a core or for the core and a cladding is inserted into a glass pipe (1) for the cladding and heated by a heater (3) while the pressure inside the glass pipe (1) is reduced. After at least one of either the glass pipe (1) or the glass rod (2) is elongated, the glass pipe (1) and the glass rod (2) are formed into a single unit, and then the glass pipe (1) and the glass rod (2) are elongated until the outer diameter of the glass pipe (1) becomes a predetermined diameter.
