摘要： The invention is to provide an optical fiber cable in which an end of an optical fiber core is prevented from being dragged inside the main cable body part upon the application of a tension on the optical fiber cable, and which prevents the increase in transmission loss and breakage of the optical fiber core caused by the movement of the optical fiber core near the connection point. The invention can be characterized in that an optical fiber cable is formed in such a manner that yarns are stranded in a periphery of the stack of the optical fiber ribbons, and an outer sheath of the main cable body part is formed with a tension member united thereto on the periphery of the yarns.

摘要： An optical fiber cable in which optical fiber ribbon stack can be accommodated in a cylindrical space efficiently and which has excellent loss characteristic. A plurality of optical fiber ribbons 1 are stacked. Cushioning fillers 2 are disposed around the optical fiber ribbon stack 1.

摘要： An optical cable has a plurality of one-groove spacers 3 which are twisted in one direction around a central member 1. Anti-tensile elements 2 are arranged in the central portion of the central member 1. Each one-groove spacer having a single groove which is linear lengthwise and substantially square in cross section and holding a stack of a plurality of optical fiber ribbons 4. The inner width and the height of the side walls of the groove of the one-groove spacer are set greater than the diagonal length of the stack. Therefore, the transmission loss becomes reducible because the contact portions of the optical fiber ribbons with respect to the side walls of the grooves vary in the longitudinal direction, thus preventing a specific number of optical fibers from being continuously subjected to edgewise pressure.

摘要： An optical cable has a plurality of optical fibers. The optical fibers are contained in fiber containing cavities of chamber elements. Each chamber element has a bottom part and a pair of side wall parts, which defines a fiber containing cavity. The individual chamber elements containing the optical fibers are assembled around a thickening layer in an S-Z strand. Each side wall part is formed such that its thickness gradually decreases from its base end portion toward free end portion. Also, the thickness of the bottom part is greater than the thickness of each side wall part.
