Vehicle-Inside Phase-Stable Fiber-Optics Network for Distributing Reference Radio-Frequency Signals

An advanced high quality and cost-efficient approach to solve an issue of phase distortion in onboard fiber-optic network delivering a set of reference radio-frequency signals is proposed and demonstrated using a wavelength division multiplexing technique. The basic distortions in analog fiber-optics link with an emphasis on the key sources of phase errors such as phase noise, jitter, and wander are reviewed. The approach is experimentally validated during field tests in realistic aircraft environment.
