Optical multiplex technique
Abstract
Survey and short description is given of the devices reviewed in the literature. About 50 articles and books were analyzed. Stress is laid on duplex-transmission on single fiber and special multimode optical fibers. Recently a fiber material with very low attenuation was produced. Most interesting is the wavelength-multiplex where the different wavelengths represent the different channels. It gives simple multiplexes with good data. Waveguides can be made in the substratum by ion implanting and several components can be placed on the same chip. Description of a duplex telephone coupler on a single-fiber is given.
