摘要： An optical fiber core consists of an optical fiber, an ultraviolet curable resinous layer which covers an outside circumferential part of an optical fiber, and a covering layer covering an outside circumferential part of ultraviolet curable resinous layer. In addition, the covering layer is composing of a first covering layer using flexible thermoplastic resin and second covering layer using thermoplastic resin of semi-hard or hard material in order that it sufficiently fulfills squeezing, tensile, bending, temperature, and lateral pressure characteristics and an economic efficiency.

摘要： A flat optical fiber cable is composed of an optical fiber ribbon cord which is comprised of tensile strength fiber having a rectangular shape covering an outside circumferential part of several optical fiber cores which are parallel one another and a sheath covers an outside circumferential part of the tensile strength fiber. The tension member is parallel to both sides of the optical fiber ribbon cord forming a row, and the outside circumferential part of the tension member and the optical fiber ribbon cord is covered with a sheath having a nearly oval shape. Because the flat optical fiber cable is formed in this way, it is easy to construct and assemble terminals and damage to the optical fiber and deterioration of performance is prevented.

摘要： At least an optical fiber of more than two pieces are arranged at least a tension member or more in a row, and the outside circumferential part of tension member and optical fiber is covered with a sheath so as to become a nearly oval shape. In addition, at least a torn slot or more is formed the outside circumferential part of a sheath. Therefore, it can be cut the end part of a sheath simply at the time of terminal management without the fact that an optical fiber makes damage and is added to power.
