Wavelength-Division Multiplexing Of Avionic Digital Control Signals

Proposed wavelength-division multiplexing optoelectronic system aboard aircraft transmits digital control signals from central flight-control computer via optical fibers to multiple distributed processors, actuators, and sensors. In comparison with serial TDM communication systems, this system offers potentially higher data throughput, greater tolerance to transient induced faults, and lower bit-error rates. Also immune to electromagnetic interference at suboptical frequencies.
