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

The present disclosure provides a process for producing a loose tube for a totally gel-free fiber optic cable and a device for molding the same, and relates to the technical field of processing and manufacturing of optical fibers and optical fiber cables. The process for producing a loose tube for a totally gel-free fiber optic cable according to the present disclosure comprises: extruding a loose 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; threading an optical fiber or an optical fiber ribbon into the loose tube. The process for producing a loose tube for a totally gel-free fiber optic cable according to the present disclosure alleviates the technical problem in the related art that the loose tube tends to have a flat shape when molded by extrusion, and the optical fiber is likely to adhere to the loose tube, which causes an unsatisfactory attenuation index of the optical fiber.
