Abstract

PURPOSE:To prepare an inexpensive optical fiber of quality according to the purpose of use, by making the area ratio of a synthetic quartz rod in any cross section of a quartz tube containing plural synthetic quartz rods and molten quartz rods a desired value, and spinning the resultant quartz tube. CONSTITUTION:One synethetic or molten quartz rod 3 or 2 is placed in the center of a quartz tube 1, and the molten and synthetic quartz rods 2 and 3 having almost the same diameter as the quartz rod 3 or 2 are plced on the outer periphery thereof to be in contact with one another. On this case, lines connecting the centers of the respective outer molten and synthetic quartz rods 2 and 3 are preferably arranged to form almost a regular hexagon. The quartz tube 1 in this state is then spun, and a silicone resin is applied to the outside thereof to prepare a silicone-clad optical fiber. The ratio between the number of the rods 2 and the rods 3, i.e. the area ratio of the rod 3 in any cross section of the tube 1 is determined according to the purpose of use of the optical fiber, and the optical transmission characteristics can be optionally set.
