Abstract : Information transfer requirements of three aircraft platforms are investigated to determine the applicability of fiber optics to naval aircraft data bus systems for the 1975-1980 time frame. Multiplex systems and data bus designs proposed for these platforms by industry sources are examined and this data is utilized as a base to project the characteristics of the near future fiber-optic data bus system. The major factors of data bus design, control mechanization, and bus structure or configuration are considered. The control mechanizations of command/response and polling are compared. Technqiues for implementing the fiber-optic data bus system and associated problems with the alternative approaches are presented. 'Star' coupler and 'T' coupler configurations are discussed.
