Fiber optics - light as a transmission path

Glass fibers are created when long, thin fibers are drawn from a silicate melt. These light-conducting media are then used in optics and laser technology, but are also increasingly used in data technology. It is above all the unheard-of 'bandwidth' of up to 100 TBit/s that makes fiber optic cables the ideal data transmission medium. Optical fibers consist of a light-conducting core, a shielding cladding and a robust protective jacket. Today's fiber optic cables can bridge distances of up to 100 km without any intermediate reinforcement.
It is not only the enormous capacity of fiber optic cables that makes them the future standard for all data traffic. Fiber optic cables are also absolutely insensitive to electrical and magnetic interference factors. And - last but not least - they are still virtually 'tap-proof'. One problem is the sensitivity of open fiber optic cables, e.g. in offices.
