Abstract: The technology of optical waveguide systems has developed rapidly over the past few years, and they now appear to offer vast new capabilities in urban communications. A review and a status report of this technology is given; glass fiber waveguides are discussed in some detail because they show considerable promise for interactive networks. Optical sources, detectors, and integrated optical circuits are discussed.

TL;DR: In this paper, the most important factors involved in the design of an optical fiber communications link are discussed, including source power, source-fiber coupling efficiency, and fiber losses, and a representative link design is made to illustrate these various factors.
Abstract: This paper discusses the most important factors involved in the design of an optical fiber communications link. The system signal-to-noise ratio is determined by many factors, including source power, source-fiber coupling efficiency, and fiber losses. Noise arising in such links, especially that related to detection, is treated in some detail. In addition to signal-to-noise considerations, system components must be chosen to provide the necessary fidelity of information transmission. Sources and detectors have limited frequency responses, and various dispersive effects are associated with light propagation in fibers. A representative link design is made to illustrate these various factors. Although many things must be considered in optimizing the design of a practical fiber link, an understanding of those treated above permits a realistic estimate of the characteristics and potentialities of optical links to be made for any given system requirement.© (1975) COPYRIGHT SPIE--The International Society for Optical Engineering.
