Abstract
The importance of optical fibre aerial cables for the communication
networks of power utilities is rapidly increasing since
several years. At one hand their advantages for transmission of
information are well-known. On the other hand their mechanical
properties make them well suited for installation in overhead
lines: They are light weight, they can be attached to the
conductor and they can easily be installed in existing towers.
From the point of view of the fitting-manufacturer there is
little difference between metallic armoured optical cables and
conventional selfsupporting aerial cables. However, the optical
fibre's sensitivity to radial stresses must be taken into
account.
For non-metallic optical cables special criteria, for example the
creep of the cable sheath must be considered. The following
explanations give a survey on the state-of-the-art fittings for
optical fibre aerial cables.
