Abstract : This document is the final report of an initial study of the optoelectronic aspects of avionic systems. Airborne avionics systems are moving toward the use of party line multiplex data buses for the transmission of the growing number of digital signals found in modern aircraft. Optoelectronic technology provides a data bus interface system consistent with military requirements that is potentially far superior to wire techniques. The optoelectronic interface is also useful for point-to-point transmission of wide-band analog and digital signals that are not included in the multiplexed data bus system. The primary objective of this program is to study coherent and non-coherent optical components, devices and techniques to determine their applicability to a flexible high-speed data bus. This initial study has emphasized detailed investigation of specific topics within the subject area and has not attempted to treat all aspects of the total problem. Optoelectronic data transmission is based on the use of multimode, low-loss fiber optic bundles with non-coherent light emitting diodes (LEDs) and silicon photodetectors. Analysis and characterization of the individual components are presented along with a description of the physical organization of an optoelectronic data bus.
