EFFICIENT DESIGN TECHNIQUE FOR WAVELENGTH DIVISION MULTIPLEXING

摘要

OF THE DISCOSURE More than ten different wavelength channels are multiplexed over a single optical fiber for use in optical slip ring assemblies. The ends of multimode fibers, through which light signals of different wavelengths are transmitted, are packaged and fused to the end of a large core fiber. The single large core fiber in which the combined signals are transmitted can be used in a optical slip ring asssembly in the same way as a single fiber containing one wavelength. The alignment accuracy is greatly enhanced for the large core fiber.
