摘要： PROBLEM TO BE SOLVED: To reduce the refractive index of a clad in a plastic primary coated optical fiber (POF) without depending on material. SOLUTION: An outer tube 12 with a large number of fine pores 33 is formed. A core polymer is put in the outer tube 12 to constitute a core material 30 by rotational polymerization, and a preform 21 is prepared composed of the outer tube 12 and the core material 30. The POF is obtained by heating and drawing the preform 21. A large number of fine pores 33 of the outer tube 12 are dispersed through the heating and drawing, so that a number of micro pores are formed in the clad of the POF. The size of the micro pores is set to 1-1,000 μm, and the quantity thereof is set 1-70 vol%. The refractive index of the clad is reduced by these micro pores. Even if the same material as the outer core material is used for the clad, a clad having a lower refractive index than the outer core can be obtained, thereby expanding the selectivity of the base material for the clad. Thus, the POF having a superior affinity, a high NA and a high transmission rate can be obtained. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To obtain a plastic optical fiber cable with which thermal contraction is suppressed. SOLUTION: A preform is obtained by forming a core part having a GI type refractive index profile in a hollow cylindrical clad pipe. A GI type POF can be obtained by heating/fusion-drawing the preform. A GI type core wire 16 is obtained by covering the outer circumferential face of the GI type POF with polyethylene to form a protective layer 123. The GI type core wire 16 is arranged with a large number of aramid fibers on the outer circumference and covered with polyvinyl chloride to form the outermost layer 125, so that the plastic optical fiber cable 20 is obtained. The aramid fibers become a loose-type coating buffer layer 124, relaxing a stress imparted radially to the optical fiber cable 20. The optical fiber cable 20 is annealed at 60°C for 17 hours. Since the polymer of the outermost layer 124 is reoriented, longitudinal contraction is suppressed in the optical fiber cable 20 even when heat is applied thereto. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To suppress air bubbles in manufacturing a preform, and to reduce loss in manufacturing steps. SOLUTION: A raw material for an inner core is injected into a clad in which an outer core is formed on the inner surface, and the clad is loaded in a polymerization container 38.

A radical polymerization initiator and a chain-transfer agent are added to the outer core and the inner core raw material, and a monomer for the inner core is a radical polymerization compound. While the polymerization container 38 is being rotated, the reaction between the monomer for the inner core and the outer core and the polymerization reaction of the monomer for the inner core are performed. The obtained plastic optical fiber preform is formed with the cores on the whole inner surface of the clad without generation of air bubbles and the whole length can be made into a POF (plastic optical fiber) by extension. The POF to be obtained has an excellent transmission characteristic. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce a clad loss due to volume decrease in core polymerization of a preform. SOLUTION: An inner core is formed by tying an extension member 51 to one end part of a clad 12 provided with an outer core, and by injecting a monomer for the inner core into the outer core together with dopant or the like for polymerization. Before injecting the monomer, a volume ratio of the volume of the monomer for the inner core before polymerization to a polymerized body obtained after polymerization is obtained beforehand, and then an injection amount of the monomer for the inner core is determined so that the inside of the clad is filled with the core after polymerization. As to the plastic optical fiber preform thus obtained, the inside of the clad is filled with the core and the clad does not have a loss part, but the plastic optical fiber can be manufactured without waste. The optical fiber obtained has an excellent transmission characteristic. COPYRIGHT: (C)2006,JPO&NCIPI
