| Zusammenfassung: | A single mode optical fiber is disclosed. The refractive index profile of the fiber comprises a depressed-index or trench region (22) in the cladding region. By suitable adjustment of the position, width and index of the trench region, one or more fiber characteristics can be improved, relative to a similar fiber that does not comprise an index trench. |
