摘要： PROBLEM TO BE SOLVED: To enable visually confirming a communication state of a plastic optical fiber. SOLUTION: Visible light as an optical signal to be transmitted is made incident from an end face of the plastic optical fiber. A clad 22 has a scattering structure which scatters the visible light and emits it from the peripheral surface outside the plastic optical fiber. This scattering structure is a structure differing in density depending on positions in the clad 22. This structure is formed by partially changing, or the like, the crystal structure of a polymer. Thus, the core 21 transmits most of the visible light, and a part of the visible light is scattered in the clad 22 and is made to exit outside from the peripheral surface of the plastic optical fiber 11. Therefore, it is possible to visually check the 2nd wavelength light, and it can be judged whether or not communication is underway, and whether or not the plastic optical fiber 11 is disconnected on the way, and a disconnected point can be judged.

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
摘要翻译：要解决的问题：降低塑料初级涂覆光纤（POF）中的包层的折射率，而不依赖于材料。解决方案：形成具有大量细孔33的外管12。将芯聚合物放入外管12中，通过旋转聚合构成芯材30，制备由外管12和芯材30构成的预制件21.通过加热和拉伸预成型件21获得POF。外管12的大量细孔33通过加热和拉伸分散，使得在POF的包层中形成多个微孔。微孔尺寸设定为1-1000μm，其数量为1-70体积％。通过这些微孔，包层的折射率降低。即使使用与外芯材料相同的材料作为包层，也可以获得折射率比外芯低的包层，从而扩大了包层的基材的选择性。因此，可以获得具有优异亲和力，高NA和高透射率的POF。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an optical fiber cord capable of preventing force from applying onto optical fibers.
SOLUTION: The optical fiber cord 2 has two lines of optical fibers 8 and a high-tension wire 19 which is arranged between these optical fibers 8. The optical fiber 8 is covered with a first covering part 20 by being closely adhered to it. A second covering part 21 consists of optical fiber parts 21a each of which covers the optical fiber 8 and the first covering part 20 and a connecting part 21b which covers the high-tension wire 19. The thickness D4 of the connecting part 21b is made thicker than the thickness D3 of the optical fiber part 21a. When the optical fiber cord 2 is passed through the inside of piping, force is applied to the connecting part 21b and large force is not applied to the optical fiber parts 21a. Thus, the optical fibers 8 are never deformed, and the lowering of communication characteristics can be prevented.

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
