The invention also proposes optical fibers verifying the above criteria and suitable for compensating the chromatic dispersion of step index or dispersion shifted line fiber. The proposed criteria compensate chromatic dispersion and chromatic dispersion slope in wideband transmission systems, e.g. in C band and L band transmission systems, for wavelengths from 1530 to 1620 nm.

    摘要： An optical fiber exhibiting monomode behavior in-cable over a range from 1300 nm to 1625 nm and having, at a wavelength of 1550 nm: a dispersion from 5 to 11 ps/(nm.km); a ratio between dispersion and dispersion slope from 250 nm to 370 nm; a derivative of effective surface area with respect to wavelength less than or equal to 0.14%/nm; a chromatic dispersion cancellation wavelength &lgr;0 less than or equal to 1370 nm; and an effective surface area greater than or equal to 50 &mgr;m2. The proposed criteria limit variations in non-linear effects in the fiber over a wide range of wavelengths and limit the dispersion to be compensated; also, the fiber can be compensated in a transmission system by chromatic dispersion compensating fiber used conventionally for stepped index fiber. The limit on the effective surface area slope avoids the need to treat individually the various wavelengths used in the transmission system.
