Advanced fiber optic networks using optical processing for future commercial aircrafts: multiple-access techniques and new hardware design

摘要

Abstract: In this paper, we investigate the use of the advanced fiber optic multiple-access networks in future high-performance commercial aircrafts to support real time on-board flight control, sensing, voice communications, and TV distributions. Novel tunable optical code division multiple-access (OCDMA) networks using prime-code sequences are designed, which can be quickly programmed to generate the required OCDMA sequences. Using the newly proposed OCDMA technique can efficiently build high-speed sensor data distribution networks which can guarantee parallel data communications and multiple connections to support real-time sensor data processing and distributed control. Due to the channel independence and protocol transparence of wavelength- division multiplexing (WDM), the WDM-based hybrid multiple-access techniques are very attractive to future avionics systems integration, which can achieve high communication efficiency and network utilization. !13
