摘要： PROBLEM TO BE SOLVED: To provide an overcoat core wire in which an overcoat layer can be reliably removed and, moreover, the length of the overcoat layer reliably removable at one time operation is longer as compared with the conventional one.
SOLUTION: The overcoat core wire 19 has such a structure that a coated optical fiber 1 made by covering a glass fiber 30 with a UV-curable resin layer 31 is further covered with the overcoat layer 16, wherein the overcoat layer 16 comprises: a first overcoat layer 16a which covers the outer circumference of the coated optical fiber 1 and comprises the UV-curable resin containing an additive having a molecular weight of at least 5,000, of providing strippability for the coated optical fiber 1; and a second overcoat layer 16b which covers the outer circumference of the first overcoat layer 16a and comprises the UV-curable resin capable of providing a crosslinking density larger than that of the first overcoat layer 16a on the contact region having a thickness of 3 μm to 20 μm, in contact with the first overcoat layer 16a.

摘要： PROBLEM TO BE SOLVED: To provide a coated optical fiber having a satisfactory balance between a removable property, capable of easily removing the outermost covering layer from the release colored layer and an adhesion property between two layers of the order, capable of suppressing increase in the extrusion amount.
SOLUTION: The coated optical fiber 10 comprises an optical fiber 13 comprising a bare optical fiber 11 and an inner cover layer 12 which is arranged on an outside circumferential surface of the bare optical fiber, and the release colored layer 14 and the outermost covering layer 15 which are arranged in stack on the outside circumferential surface of the bare optical fiber, where the adhesive strength with respect to the outermost covering layer for the release colored layer falls into a range of 2.0 to 4.5 [N].
