Abstract: A single mode optical waveguide fiber having a relatively large effective area and low dispersion includes a segmented core having at least two segments (30, 32, 34) each defining a radius, a refractive index profile and a relative refractive index percent. The waveguide fiber also includes a clad layer (36) surrounding and in contact with the core and having a relative refractive index. The refractive index profiles are selected to provide total dispersion at a wavelength of about 1550 nm of within the range of about 11 ps/nm-km to about 14 ps/nm-km, and total dispersion slope at a wavelength of about 1550 nm of within the range of about 0.045 ps/nm2-km to about 0.055 ps/nm2-km. The refractive index profiles are further selected to provide an effective area greater than or equal to 60 µm2, and attenuation at a wavelength of about 1550 nm of less than or equal to 0.22 dB/km.

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 νm2. 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 % νm2, the outer profile volume is in the range 3.70 to 13.75 % νm2, and the ratio of outer to inner volume is in the range 1.5 to 4.3.

Abstract: A long haul, broadband DWDM system that has been optimized by the proper selection of the distribution of total dispersion compensation. Dispersion compensation is utilized at both the receiver and the transmitter ends. System performance is dependent on the ratio of compensation split between the transmitter and the receiver. A system operated in the non-linear regime can be compensated to operate with low BER and with reduced penalties due to residual dispersion effects, even when the spread of the total accumulated dispersion between the extreme channels in a broadband system exceeds 1,000 ps/nm.

Abstract: Disclosed is a dispersion shifted optical waveguide fiber having low but non-zero dispersion over an extended wavelength window that includes wavelengths, from 1470 nm to 1625 nm. Waveguide fiber core refractive index profiles exhibit the desired dispersion performance while maintaining resistance to pin array and lateral load bending at least equivalent to standard waveguide fiber. Attenuation over the operating wavelength range is low and zero dispersion wavelength is typically less than 1450 nm.
