Abstract
Research and development in the field of optical fiber transmission technology saw dramatic progress in the first 10 years (1970–1980). From the first low-loss optical fiber and first room-temperature cw semiconductor injection laser in the laboratory to the field trial of optical fiber transmission systems, the field is unique in the rapid deployment of laboratory advances in component and system technology to commercial systems. Transmission systems based on optical fiber communication technology have indeed revolutionalized the field of communications and are leading the change toward a totally digital network which promises a variety of new functions and features based on the concept of broadband integrated services digital networks (BISDN). The broadband ISDN promises to provide services including low-speed telemetry, high-speed data, high-quality audio, high-definition TV distribution, and two-way video in addition to the POTS (plain old telephone service) that we have today on paired copper wires to the home.
