PROBLEM TO BE SOLVED: To provide a fire-retardant coated optical fiber tape having a maintained cross-sectional shape. SOLUTION: The coated optical fiber tape comprises: a first tape coating for coating optical fiber cable cores and a second tape coating. One of the first tape coating and the second tape coating comprises an ultraviolet-curing resin wherein at least one fire-retardant substance A out of phosphate, phosphonic acid ester, phosphine oxides, a fire-retardant nitrogen-containing heterocyclic ethylenically unsaturated compound, phosphorus-containing acrylate, methacrylate functional oligomer, and their mixtures, and at least one fire-retardant substance B out of metal hydroxide, metal carbonate, metal oxide, and their mixtures are added to radiation-curing monomer and oligomer, and the other comprises an ultraviolet-curing silicone resin.
