摘要： A negative total dispersion waveguide fiber having low attenuation and compresses the launched signal pulse when the laser is positively chirped. The laser is provided at optimum bias, which results in positive chirp, but no dispersion penalty is incurred in the link. The waveguide fiber is used a dispersion compensating fiber in a high performance multiplexed telecommunications link. Curve (96) in figure 8 representative of a link comprising fiber having negative dispersion waveguide fibers. Curve (98) is representative of a link comprising fiber having negative dispersion at 1550 nm in accordance with the invention. Curve (100) is representative of a link comprising fiber in accordance with the invention and a laser source that is even more positively chirped thanthe laser to generate curve (98).

摘要： An optical waveguide fiber including a central core region extending radially outward from the centerline and having a non-negative relative refractive index percent profile. The total profile volume is less than about 6 %- m2. The optical fiber exhibits an effective area of greater than about 60 m2 at a wavelength of about 1550 nm, a dispersion slope of less than 0.07 ps/nm2/km at a wavelength of about 1550 nm, and a zero-dispersion wavelength of less than about 1450 nm.
