摘要： An optical cable has an S-Z stranded part in which plurality of chamber elements containing optical fibers are assembled around a central member in an S-Z strand in the state where their bottom faces are in contact with the central member. Each chamber element has such a characteristic that its flexural rigidity in the depth direction of its fiber containing cavity is smaller than that in the widthwise direction thereof. Assuming, of distortion energy of the chamber element in an S-Z reverse portion within the S-Z stranded part, the distortion energy in the case where the bottom face of the chamber element is in contact with the central member to be U.sub.1, and the distortion energy in the case where a side face of the chamber element is in contact with the central member to be U.sub.2, a relational expression of .DELTA.U=U.sub.1 -U.sub.2 .ltoreq.0.2(mJ/mm) is satisfied.

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.

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： In an optical cable made by forming a sheath on enclosing one or more optical fiber cores and a tension member, high reliability is obtained through the avoidance of adverse effects on the optical fiber core of a curving tendency of the tension member prevailing over the resistance of the sheath to curving (for example, due to the installed optical cable being heated by electrical equipment in proximity) and the optical cable consequently curving. Taking the plane containing the curve formed by the tension member due to its curving tendency as a base plane, the optical fiber core is disposed in the proximity of the position of the image formed when the tension member is projected in a direction perpendicular with respect to the base plane onto a flat plane separate from and parallel with the base plane. If the optical fiber core is an optical fiber ribbon comprising a plurality of optical fibers lined up in a flat plane and coated en bloc, then as an additional condition, an alignment line obtained by joining the centers of the optical fibers at both sides of the optical fiber ribbon is disposed perpendicular to the base plane.
