摘要：[Problem] When bundle materials having a width greater than the thickness incross-section are wound around an optical fiber bundle in an SZ shape, twisting occurs inthe bundle materials at locations at which the winding direction is inverted, and thebundle materials become joined in a shape of being upright from the optical fiber bundle.[Solution] The present disclosure is an optical fiber unit provided with an optical fiberbundle in which a plurality of optical fiber core wires are bundled, and a plurality ofbundle materials. One of the plurality of bundle materials is wound on the outerperiphery of the optical fiber bundle along the longitudinal direction of the optical fiberbundle while alternately inverting the winding direction, and joined to another bundlematerial at locations at which the winding direction is inverted. The width of the bundlematerial is less than 20 times the thickness of the bundle material in cross-section.
