Military avionics applications require the high reliability, which offers the challenge to design feasible avionics fiber-optic (AFO) data buses. In this paper, we present the new design methods to implement the highly reliable AFO data buses by using today's mature optoelectronic devices. To effective solve the problems associated with optical power budget and high reliability, the active-coupler architectures for both single-wavelength and multi- wavelength AFO data buses are proposed. The topologies are discussed in detail. To ensure the high-reliability data transmission on the buses, three efficient modulation techniques are presented, which can significantly reduce the complexity of optical transceivers and the processing time at receivers compared to using the modulation scheme recommended by the MIL-STD-1773. The hardware design of the proposed active-coupler-based AFO data buses is also described.
