Abstract: The Avionic oriented Fibre Channel network is a real-time and deterministic communication network. Optical network with wavelength division multiplexing (WDM) transmission technology has been targeted as the technology of choice to realize the desired avionic network of the future due to its lightness, high-capacity and transparency to multi-protocols. Based on the trend towards avionic network, we propose a fiber channel (FC) over WDM architecture on avionic network. The delay deterministic of FC and the bandwidth extensibility of WDM are integrated to satisfy the communication requirements of avionic network, and the existing avionics FC network can be seamlessly upgraded. We establish an FC over WDM ground experimental environment based on independently developed FC emulator, and the experimental results on functional verification and system performance analysis indicate that the adoption of WDM and optical switching in avionics fiber-optic network is feasible.
