Câbles à fibres optiques pour centrales à énergie fossile

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. 

They can be used in fossil power plant. When they are armoured, they are well adapted to underground use in industrial applications where mechanical protections are needed.
