Zusammenfassung:A low-loss single mode fiber with low total dispersion within the wavelength range 1.25-1.385 mu m and low added cabling loss is disclosed. The fiber has relatively high DELTA to assure low cabling loss. The high DELTA is obtained, however, without paying a cost in high material dispersion by providing at least 20 percent of the DELTA by down-doping of the fiber cladding.
