Non-metallic long span aerial cable with optical fibres for the use at 1.3 micrometers

For the use in overhead power lines the application of fully dielectric optical fiber cables is very useful. It is shown, that it is possible to construct long span aerial cables for spanwidths of up to 1000 m. First results in test installations with graded index and single mode fibers at 850 and 1300 nm are reported. From these results estimations for system designs are derivated.
