Abstract
PURPOSE: To obtain a metal-clad optical fiber having stable form, by spinning the metal-clad preform of the optical fiber rod under heating with both heating furnace and a radiofrequency heating means.
CONSTITUTION: A coated preform 1 composed of the optical fiber rod 2, the metal pipe 3 closely covering said fiber rod 2, and the quartz glass pipe 4 closely covering said metal pipe 3, is prepared in advance. The preform 1 is introduded into the heating furnace 6, and when it reaches the desired positin in the furnace 6, a high- frequency magnetic field is applied thereto by the high-frequency heating means 5 placed near the furnace 6. The pipe 3 is heted with the furnace 6 and the heating means 5, and the melting of the pipe 3 and the softening of the rod 2 and the pipe 4 take place simultaneously. The preform 1 of this state is integrally spun by conventional process to obtain the objective metal-clad optical fiber.
