Optical communications system for transmitting signals via light conductors, has mode coupler or mixer for reducing dispersion at or after mode transition and before transmission path

摘要

The system has a LED or laser (1) on the input side from which light is fed into a monomode fiber (3). A multi mode fiber (7) forms the transmission path (17). A transition from the monomode fiber to the multi mode fiber is arranged before the transmission path. The light wave transmission is based on an analogue data transmission. A mode coupler or a mixer (13) for reducing dispersion, especially mode dispersions, is arranged at the transition, or after it, and before the transmission path.
