A year later, Corning Integrated produced optical fibers with a stepped refractive index profile and reached an attenuation coefficient of 20 dB/km at a wavelength of 633 nm. For the first time, a quartz optical fiber passed a gentle beam at a distance of up to 2 kilometers. Quantum data transfer is at the moment creating similarly as an experiment and commercial use over quick distances. In the present day, optical fiber is used in lots of industries besides Telecom. It includes X-ray machines,...
