These 10, 25, 50 or 100 pair copper cables with waterproof polyethylene insulation, with or without lead sheathing, are used for extensive inter-building connectivity.
Non-polyethylene versions without lead are used for internal networks in non-hazardous areas.
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. All materials used to manufacture this FOH cable are halogen free. This ensures that non corrosive and low toxic gases are emitted in case of fire and allows an installation inside buildings.
