Advantages of fiber optic technology in an aircraft control system are realized at the system level and not in sensors or components themselves. Improved system reliability and performance, and reduced electron optic (e-o) interface size, weight and cost may be realized with the use of fiber optic technology. This paper provides a discussion on the Electro-optic Architecture conceptual designs, sensor multiplexing approaches and key design requirements for the control system of the aircraft. In addition, a comparison of Time and Wavelength division multiplexed systems (TDM and WDM) for digital position sensors configured into a network is made to identify which approach meets system design criteria more efficiently. It is concluded that present WDM sensor interogation time must be drastically reduced to be compatible with the aircraft control system and that both approaches require a highly reliable optical source which provide adequate power and spectral bandwidth.
