Abstract
Process for making preforms for multicore optical fibers. According to this process, several elementary preforms are made, a first machining is performed on them such that a chosen geometric model will be obtained after they are assembled, a second machining is performed such that the assembly (11) has at least one hole (12), the preforms are assembled and an induction furnace (18) is used to fuse the preforms, while creating a vacuum in each hole.
