Abstract
A novel configuration for an all-optical bus-topology data-multiplexing system is proposed in which multichannel signals are sequentially multiplexed by frequency-division multiplexing (FDM) on a single-wavelength optical carrier by cross-phase modulation (XPM) in nonlinear fibers (NLFs) with subcarrier-modulated optical data signals. By using highly NLFs for XPM generators and providing amplitude-modulated subcarrier-multiplexed optical signals generated with directly modulated lasers or optical beat signals at multiple local connection points, we successfully demonstrate sequential all-optical FDM of data signals on a single-wavelength optical carrier followed by error-free data transmission through a standard fiber.
