PURPOSE:To improve the workability at the time of connecting optical fibers, by providing an oleo-resin layer at the periphery of an optical fiber strand. CONSTITUTION:An optical fiber strand 1 is constituted of quartz optical fibers consisting of a core and cladding, a primary coat 3 made of silicone thermosetting resin which is formed on its outer periphery and a buffer coat 4, and an oleo-resin layer 5 selected among thermoplastic resins and thermosetting resins is provided at its outer periphery. A fine viscous film is formed between the optical fiber strand 1 and the oleo-resin layer 5, and as the relative friction is decreased, the workability at the time of connecting the fibers is improved. |
