Abstract

PURPOSE:To prevent increase in transmission loss at the time of winding without increasing the outside diameter of an optical fiber unit by specifying the Young's modulus and thickness of a sheath. CONSTITUTION:Plural pieces of optical fibers 2 are aggregated around a non-metallic tensile body consisting of, for example, fiber reinforced plastic (FRP), etc., and the sheath 3 consisting of a heat resistant resin such as fluoroplastic is formed thereon. The Young's modulus of the sheath 3 is specified to 20kg-mm<2> or above and the thickness thereof to >=0.5mm. The optical fiber unit for an optical composite overhead earth wire which does not increase the transmission loss at the time of winding even if the unit is used for the optical composite overhead earth wire of a so-called additional stringing type is thereby obtd.
