| Zusammenfassung: | An optical transmission is described which comprises a radiation source (30) and a multiple-clad monomode optical transmission fibre (10) with a negative-step index profile. In order to improve the efficiency of coupling the radiation from the source into the transmission fibre a single-clad- monomode transmission fibre (20), whose end portion which faces the source is tapered, is arranged between the source and said fibre. |
