Multimedia is an indispensable part of modern life. To cope with the huge amounts of data this involves data transmission systems that use polymer or glass fiber optic cables to transmit digital signals in the form of light. Polymer fiber optic (POF) cable is used for short-distance applications requiring high strength, such as in automobiles and local networks, while glass fiber is used for high transmission quality across long distances, for example in telecommunications networks. Rennsteig offer a wide selection of specialized fiber optic cutting, stripping and crimping tools that are available individually or in professional time saving installation kits.
