Abstract
DE 3500532 A UPAB: 19930922 The multiplexer-demultiplexer (MULDEX) system is used for optical data transmission. It achieves multiple use of a given wavelength range used as a transmission channel. The light source for the single mode transmission system may be a monomode laser. The light is transmitted via monomode optical fibres. Two optical channels (A,B) run adjacent to each other, and there is a discontinuous connection between them over N sections (S) with etched fits (g). The fits give reduced coupling and a measure of optical isolation in a regular array between coupling areas, and the whole assembly acts as an optical filter. USE - For road band optical data transmission. 4/9
