Abstract: Disclosed is a dispersion shifted single mode optical waveguide fiber having a segmented core refractive index profile in which the profile parameters are selected to provide an attenuation minimum. A set of profiles having the same general shape and dimensions is shown to have a group of profiles contained in a sub-set which exhibit a minimum of attenuation as compared to the remaining members of the set. The members of the sub-set have been found to have the lowest effective group index, ngeff, and the lowest change in beta under waveguide fiber bending.

Abstract: Disclosed is a single made optical waveguide fiber having a segmented core design. In particular, the core comprises three segments, each having characteristic dimensions and refractive index profile. By proper choice of index profile in each segment, a waveguide fiber is made which has a mode field diameter of about 9.5, low, positive total dispersion over the operating window 1530 nm to 1565 nm as well as effective area greater than 60 mum 2 .

Abstract: Disclosed is a single mode optical waveguide having a segmented core of at least two segments. The relative refractive index, the index profile and the radial dimensions of the core segments are selected to provide an optical waveguide fiber having properties suitable for a high performance telecommunication system operating in the wavelength window of about 1530 nm to 1570 nm. Embodiments of the invention having two, three and four segments are described. To eliminate non-linear effects, such as FWM and SPM, which occur in a high performance, high rate systems, the effective area of the waveguide is made to be greater than about 60 .mu.m2, more preferably greate r than 65 .mu.m2, and most preferably greater than 70 .mu.m2. The total dispersion is preferably positive and equal to at least 2 ps/nm-km at 1530 n m. This total dispersion together with a total dispersion slope less than about 0.1 ps/nm2-km insures a minimum FWM effect over the wavelength window.

Abstract: Disclosed is a single mode optical waveguide fiber having a segmented core design. In particular, the core comprises three segments (2, 6, 8), each having characteristic dimensions and refractive index profile. By proper choice of index profile in each segment, a waveguide fiber is made which has a mode field diameter of about 9.5, low, positive total dispersion over the operating window 1530 nm to 1565 nm as well as effective area greater than 60 .mu.m2. The profile is further defined by the inner and outer profile volume and the ratio of outer to inner volume. Thus, inner volume is in the range 2.28 to 3.26 % .mu.m2, the outer profile volume is in the range 3.70 to 13.75 % .mu.m2, and the ratio of outer to inner volume is in the range 1.5 to 4.3.
