PROCESS FOR PRODUCING LOOSE TUBE FOR TOTALLY GEL-FREE FIBER OPTIC CABLE AND DEVICE FOR MOLDING THE SAME

摘要

The present disclosure provides a process for producing a loose tube for atotally gel-free fiber optic cable and a device for molding the same, andrelatesto the technical field of processing and manufacturing of optical fibers andoptical fiber cables. The process for producing a loose tube for a totally gel-freefiber optic cable according to the present disclosure comprises: extruding aloose tube material into a tubular loose tube by a loose tube molding device;filling a compressed gas into the loose tube; cooling the loose tube;threadingan optical fiber or an optical fiber ribbon into the loose tube. The processforproducing a loose tube for a totally gel-free fiber optic cable according tothepresent disclosure alleviates the technical problem in the related art thattheloose tube tends to have a flat shape when molded by extrusion, and theopticalfiber is likely to adhere to the loose tube, which causes an unsatisfactoryattenuation index of the optical fiber.
