On This Day

Robert D. Maurer Born 20 Jul 1924.American research physicist, who with his colleagues at Corning Glass Works, Dr. Donald B. Keck and Dr. Peter Schultz invented fused silica optical waveguide - optical fiber. This was a breakthrough creating a revolution in telecommunications, capable of carrying 65,000 times more information than conventional copper wire. In 1970, Maurer, Keck, and Schultz solved a problem that had previously stumped scientists around the world. They designed and produced the first optical fiber with optical losses low enough for wide use in telecommunications. The light loss was limited to 20 decibels per kilometer (at least one percent of the light entering a fiber remains after traveling one kilometer). He retired in 1989.
