D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

Charles Kuen Kao is a Chinese, British and American scientist, engineer-physicist, winner of the Nobel Prize in Physics (2009) for achievements in the field of light transmission over fiber optic channels, known as the "Father of fiber communications."
Charles Kuen Kao was born on November 4, 1933 in Shanghai, China.
In the mid-1960s, the development of telecommunications systems required new ways to transmit a signal with greater speed and less loss. An employee of the British company Standard Telecommunication Laboratories (STL) Charles Kao started to investigate the issue of signal attenuation in an optical fiber. After collecting all possible samples of materials for the manufacture of optical fibers, he came to the conclusion that attenuation depends only on the degree of purity of such material for the manufacture of optical fibers.
Charles Kao is the author of key research in the field of development and practical application of fiber optic technologies, which significantly influenced the development of the telecommunications industry.
