摘要： PURPOSE:To avoid the bending of an optical fiber which is caused by the contraction of a sheath, by burying a filament containing a number of uneven areas on its surface into the sheath. CONSTITUTION:Optical fibers 5a and 5b are enclosed by a buffer member 7 such as a cotton cord, etc. and then covered with a sheath 6. Thus an optical fiber cord 8 is obtained. A steel wire 1 having the unevenness is buried into the sheath 6 in the lengthwise direction. Plural pieces of wire 1 can also be buried symmetrically and over the entire circumference of the sheath 6. In such case, the thickness of the sheath is decreased but the change of dimension can be reduced in the lengthwise direction. The wire 1 can also be formed with a reinforced plastic (FRP) cord.

摘要： PURPOSE:To avoid elongation and stress in an optical fiber, by fixing an optical fiber meandered along a band holder, and storing it in a pipe. CONSTITUTION:An optical fiber 1 which is meandered in a specific pitch and width is fixed from both sides with a band shape holder 2 such as sticky plastic tape. This is drawn in an aluminum pipe 3, and a conductor core wires 4 such as aluminum wires or aluminum coated steel wires are twisted around the pipe 3 to obtain an optical fiber composite type overhead line. When the overhead line is elongated with tension, the plastic tape is elongated and the optical fiber becomes in a straight line shape, allowing to almost zero the elongation of the optical fiber and to prevent the increase in the transmission loss.
