Can ADSSS fiber optic cables be used inside electrical cables
In the design of the cable, the internal glass optical fibers are supported with little or no strain, to maintain low optical loss throughout the life of the cable.OverviewAll-dielectric self-supporting (ADSS) cable is a type of that is strong enough to support itself. No metal wires are used in an ADSS cable. Optical fibers are either supported in loose buffer tubes, or arranged in a ribbon configuration. To prevent strain on the fibers, most types provide the fibres with excess slac. Fittings used with ADSS cable may be tension type, used at dead-ends where the cable terminates or changes direction, or may be suspension type, only holding the weight of a span with tension transmitted through th. Cables must be designed for the worst-case combinations of temperature, ice load, and wind. An installed cable must not sag so low that it can be damaged by traffic under the line.
