Space Platform Information Distribution System: A Fiber Optic LAN Approach
Richard D. Stewart · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1989
This paper describes a design concept for a distributed system that is modular and provides a means of transferring analog signals, synchronous or asynchronous digital data (either bit serial or byte serial), and discrete status/control information in any mix. Maximum flexibility is a key feature. The system will accommodate a broad spectrum of operators and communication assets (both audio and digital), data acquisition/control system (analog or digital), and interconnection between multiple processors and peripheral devices. The architecture and protocol will accommodate both cable or optical fiber. Connectivities are established without using a central controller or switch. Analog signals can be distributed from one user to any number of other analog users without reduction in signal quality. Also, data can be distributed from any data terminal device to any other data terminal device. The flexible design allows for a wide variety of functional and operator interface capabilities with minimum impact to the hardware.
