A Study of Wavelength Division Multiplexing for Avionics Applications.
Abstract
The performance of avionics wavelength division multiplexed (WDM) fiber optic systems was analyzed using an Optical Circuit Analysis Program (OCAP) developed during the study. Design solutions were found for several sets of Air Force avionics information transfer specifications, and sensitivity analysis techniques using OCAP were used to show that the solutions were reliable. Recommendations were made on key component developments which could result in major advancements in WDM system design. These developments would include diffraction grating WDM couplers, high speed-high power light emitting diodes, and pin-FET receivers. Quantitative analysis of an avionics WDM system using these components indicates performance beyond that previously thought possible. Three specified Air Force WDM avionics systems were designed which could be fabricated using technology available in the 1983-1985 time frame. A design for a WDM demonstration system was developed which allows WDM systems to be demonstrated and WDM components to be tested. The WDM demonstration system was designed for laboratory bench applications and features a modular organization to provide for maximum user flexibility. Examples are given of the use of the WDM demonstration system for measurements of system performance parameters such as bit error rate, link delay, optical dynamic range, and rise time, and recommendations are made on key future component developments which could enhance avionic WDM systems.
