Applications
Optical fibers are mainly used to transmit information over long distances and with high bit rates. The light signal propagates along the core and the signal is reflected on the surface between the core and the cladding. The FOH cable type is based on a loose tube design, in which the fibers are protected. It contains a maximum of 24 monomode or multimode fibers. This FOH/SWA/PVC cable has a galvanized steel wires armour and a special PVC outer sheath resistant to aliphatic hydrocarbons which makes the cable well adapted to underground use in industrial applications.
