PURPOSE:To fusion splice optical fibers with high strength and to enhance reliability by shutting off the optical fibers from the atm., heating and dehydrating these fibers, and in succession forming a coating thereon. CONSTITUTION:A chamber 1 which can be hermetically closed is provided. A discharge device 2, a gas supplying device 3 for dehydration and an inorg. material supplying device 4 are connected via a piping 5 to this chamber 1. Further, a heater 6 is provided inside or outside the chamber 1. The fusion spliced optical fibers 9 are introduced into the chamber 1 and are shut off from the atm. The surface of the connected part is heated and dehydrated in the chamber and in succession, the coating consisting of the inorg. material is formed on its surface. |
