    Abstract: PROBLEM TO BE SOLVED: To provide a high-band plastic optical fiber which is high in a transmission band and is lowered in bending less. SOLUTION: This high-band plastic optical fiber is a plastic optical fiber consisting of a core which is a substantially org. polymer, a first clad and a second clad. The relation of the refractive index between the core and the first clad of the plastic optical fiber described above satisfies the relation of the following formula (I) and the relation of the refractive index between the core and the second clad satisfies the formula (II). In addition, both of the first clad and the second clad consist of a polymer or polymer mixture contg. a vinylidene fluoride unit: The formula I; 0.25 -n1clad ) -n2clad )1/2>=0.45. In the formulas, ncore denotes the refractive index of the core, n1clad denotes the refractive index of the first clad and n2clad denotes the refractive index of the second clad.

    Abstract: PURPOSE: To obtain a composition good in transparency and homogeneity even at room temp., excellent in workability when used as the clad of the optical filber or resin coating layer and capable of minimizing eccentricity and to produce an optical fiber excellent in cured transparency, adhesion to the optical fiber substrate, mechanical strength, handleability, and environmental resistance and optical characteristics and capable of maintaining high light transmission stability by forming the clad and resin coating layer of the optical fiber from the composition. CONSTITUTION: This curable composition for an optical fiber contains a composition consisting of 2-(perfluorooctyl)ethyl acrylate, hexafluoroisopropyl acrylate, trimethylolpropane triacrylate and a polymerization initiator and 0.9 to 1.1 pts.wt. of γ-mercaptopropyl trimethoxysilane, based on 100 pts.wt. of the composition. The curable composition is closely applied on the optical fiber substrate made of quartz glass and cured with UV to to form the clad and resin coating layer.

    Abstract: PURPOSE:To obtain plastic optical fibers excellent in transmission loss without coloring even when the production of optical fiber is continued for a long time such as two months or longer, by applying a heat-resistant resin sealing material on the outer wall of stuck surfaces of plate-shaped members for sealing and smoothening the faces to be adhered. CONSTITUTION:The spinning block 5 consists of three plate-shaped members 9-11. A sealing material 7 is applied on the outer wall of the stuck surfaces 6 of the members for sealing. The sealing material 7 is supplied to fill recesses on the outer wall of the stuck surfaces 6. To increase the sealing property of the spinning block 5 thus constituted, each stuck surface of the plate-shaped members 9-11 is made flat and smooth as much as possible to make the flatness small. The adhering member thus smoothened is required to have
