Development and Research of Airborne Network Communication Technology

With the continuous development of data bus communication technology and computer technology, avionics equipment put forward higher requirements for airborne data communication bandwidth, data throughput, real-time, reliability, security and so on. Avionics system is the "brain" and "nerve center" of aircraft, and airborne data bus is its key "neural network". In this paper, The development of airborne network communication technology is introduced, and the application of FC optical fiber switch structure network in aircraft avionics system is described, the airborne network communication technology of avionics system is analyzed and discussed in different stages of use, and it is pointed out that FC optical fiber data bus communication network will be widely used in the field of avionics system communication in the future.
