Abstract

Designers of electro-optic systems must possess strengths in a variety of fields. It is not unusual for a systems engineer to be proficient in mechanics, dynamics, electronics, sensors and economics. However, an optical expert of the highest caliber can have difficulty in assessing the advantage of a multi-mode optical fiber in even a simple system application. The data available on multi-mode optical fibers frequently is not presented in a form which can be readily interpreted into system concepts or parameters. The conventional presentations can be highly analytical or very philosophical. An analogy would be to require electronic engineers to design circuits using transistor data only specified in terms of mobility, volume and recombination parameters. The typical analytical approach is developed from rather sophisticated single-mode waveguide theory. An analytical extension to multi-mode optical fiber is precise, but can be difficult to interpret and apply to a specific multi-mode application. The philosophical approach allows one to feel that an understanding of fiber optics exists. However, an inability to demonstrate this understanding usually occurs when the designer is pressed to apply values to necessary system parameters. The theory of multi-mode fiber optic components is presented herein in terms of simple component and system concepts which can be comprehended by the layman. Each concept is accompanied with illustrations and sufficient equations so that a designer can develop the needed mathematical expressions to make trade-offs in system parameters and to predict system performance. The emphasis is to describe fiber transmission properties in terms which better assist the designer of successful systems.
