到達距離が減少する等の欠点がある。 However, optical fiber is weak against tension, pressure, etc.
If tension is applied to the optical fiber, if pressure is applied from the side, or if stress is applied due to extreme bending, etc., the attenuation rate of the optical signal will increase and the signal's reach will be reduced. be.

材にて包む、また銅線等の耐張力材を添えて強張
力合成樹脂にて被覆を施す等を行なつている。 In order to prevent this drawback, the optical fiber is coated with synthetic resin and the outside is wrapped with tensile reinforcing material, or a tensile strength material such as copper wire is attached and coated with high tensile synthetic resin. is being carried out.
しかし、これらは製造工程が繁雑化し、その工
程において光フアイバーに圧力が掛る、傷を生ず

殊な強力補強材を一切使用していない。 The embodiments shown in FIGS. 1 and 2 are optical fibers 1
An appropriate number of optical fiber signal wires coated with synthetic resin 2 and copper conductors 3 coated with synthetic resin 2 are lined up in a row, and a flat surface is placed on the outer periphery of the wire. It is a flat cable whose cross-sectional shape is the track shape of track and field, and is covered without gaps with an outer covering 4 made only of synthetic resin, and this flat cable does not use any special strong reinforcing material.

イバー信号線の両端部に電線を配置すると良結果
が得られる。 The diameter of the optical fiber 1 of the optical fiber signal line is smaller than the diameter of the single copper conductor 3 of the electric wire, and good results can be obtained by placing the electric wire at both ends of the optical fiber signal line. can get.
本考案の平型ケーブルは通常のケーブルと同様
に使用することができ、ケーブルの敷設作業にお
いてケーブルに張力を加えた場合、空中に敷設し
た場合等には、銅導体電線が張力を支持する故に
光フアイバーに張力が掛ることがなく、張力支持
物等を用いる必要がない。 The flat cable of this invention can be used in the same way as a normal cable, and when tension is applied to the cable during cable installation work or when it is laid in the air, the copper conductor wire supports the tension. No tension is applied to the optical fiber, and there is no need to use a tension support.
ケーブルに外部から圧力が掛つた場合、ケーブ
ルの偏平な方向に圧力が掛つた場合には両側の銅
導体電線にて圧力を受けて、光フアイバーに圧力
が掛ることを防止し、ケーブルに直角の方向に圧
力が掛つた場合には外径の大なる銅導体電線が圧
力を受けて、光フアイバーに圧力が掛ることを防
止する。 If pressure is applied to the cable from the outside, or if pressure is applied in the flat direction of the cable, the copper conductor wires on both sides will receive the pressure, preventing pressure from being applied to the optical fiber. When pressure is applied in this direction, the copper conductor wire with a large outer diameter receives the pressure, which prevents pressure from being applied to the optical fiber.
また、ケーブルを屈曲する場合には、形状が偏
平であるために偏平な面に対して直角の方向にの
み屈曲し、銅導体電線により極端な屈曲を防止す
ることができる故に、光フアイバーに屈曲による
ストレスの発生を防止することができる。 In addition, when bending a cable, since the cable is flat, it can only be bent in the direction perpendicular to the flat surface, and the copper conductor wire prevents extreme bending, so the optical fiber can be bent. It is possible to prevent the stress caused by

ことができる。(1) A plurality of parallel optical fiber signal lines whose outer peripheries are coated, and the diameter of the optical fibers arranged along both sides of the plurality of parallel optical fiber signal lines. A pair of electric wires whose outer periphery is coated with a single wire copper conductor having a diameter larger than the dimensions, and a top layer formed on the outer periphery so that the pair of electric wires and the plurality of optical fiber signal lines are buried without any gaps. It is composed of a single synthetic resin outer covering with a flat bottom and a track-like cross-sectional shape for track and field events, so even when objects with large loads are placed on it,
The load of this article can be supported by a pair of electric wires at both ends.
