摘要：An optical fiber cable includes a core including a plurality of units which areassembled and each of which comprises a plurality of optical fibers which are assembled,a pair of tension members disposed so as to face each other with the core interposedtherebetween, and a sheath covering the core and the pair of tension memberscollectively. The units are twisted so as to form a plurality of layers. The plurality oflayers includes a first layer having first-layer units formed in an SZ-twisted shape and asecond layer having second-layer units formed in an SZ-twisted shape. A twistingdirection of the first-layer units is opposite to a twisting direction of the second-layerunits in at least a portion in a cable length direction.
