摘要： A distinctive optical fiber comprises an optical fiber core, distinctive layers, and a colored layer. A plurality of the distinctive layers including fine drops of ink having a specific particle size is disposed intermittently on the optical fiber core in the longitudinal direction of the optical fiber core. The colored layer is disposed on the distinctive layers and on the optical fiber core on which the distinctive layers are not disposed. The following five requirements are required for obtaining the distinctive optical fiber excellent in distinctiveness and with low transmission loss. The thickness of the colored layer is chosen so as to be larger than or equal to 2 μm and smaller than or equal to 10 μm. The thickness of the distinctive layers is chosen so as to be larger than or equal to 0.5 μm and smaller than or equal to 2.5 μm. The length of the distinctive layers is chosen so as to be larger than or equal to 1 mm and smaller than or equal to 15 mm. The interval of the distinctive layers is chosen so as to be in the range between 1 mm and 200 mm. The occupied ratio of the distinctive layers is chosen so as to be less than or equal to 20%. The major diameter of the fine drops of ink is chosen so as to be larger than or equal to 100 μm and smaller than or equal to 400 μm.

摘要： A resin liquid is provided which is used to produce an optical fiber coating layer which does not degrade over time in long-period transmission characteristics of the optical fiber. An optical fiber in which long-period transmission characteristics do not degrade is also provided. In order to achieve these objects, the present invention provides a resin liquid for an optical fiber coating layer containing at least one resin, wherein the resin liquid contains fewer than 500 pieces of extraneous material per 1 ml of the resin liquid, which have a minimum length of 0.5 μm or more and a hardness greater than a hardness of the resin liquid after curing.
