    摘要： A plastic optical fiber cable includes: a bare optical fiber including a core made of a poly(methyl methacrylate) or a copolymer including methyl methacrylate as a major component and a cladding layer including, at least in the outermost layer, a layer made of a certain fluorine-containing olefin-based resin; and a coating layer provided on the outer surface thereof. The coating layer includes a protective coating layer, a light blocking coating layer, and a functional coating layer, the layers being provided in the order mentioned from inner side. The protective coating layer is made of a certain resin material. The light blocking coating layer is made of a nylon-based resin including, as a major component, nylon 11 or nylon 12, the nylon-based resin containing monomer and oligomer compounds derived from the nylon-based resin in an amount of a certain range. The functional coating layer is made of a nylon-based resin composition having a crystalline melting point within a certain range, the nylon-based resin composition containing a certain amount of melamine cyanurate or bromine atoms and further containing a certain amount of inorganic chromatic pigments, or the layer is made of a nylon-based resin composition having a crystalline melting point of within a certain range and an oxygen transmission rate within a certain range.
