ABSTRACT:
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.
