    • The field of the invention is that of optical fibers for use in wavelength division multiplex transmission networks. The dispersion managed optical fiber (1) for use in wavelength division multiplex transmission networks includes positive chromatic dispersion optical fiber portions (Tnull) alternating longitudinally with negative chromatic dispersion optical fiber portions (Tnull) and comprising in succession from the center towards the periphery a core having a varying index profile and then a cladding having a constant index, the outside radius of the index profile of the core, which is the limit between the core and the cladding, being sufficiently small for the optical fiber to function in monomode in-cable, each optical fiber portion (Tnull, Tnull) having at a wavelength of 1550 nm a chromatic dispersion whose absolute value is from 1 ps/nmnullkm to 10 ps/nmnullkm, a chromatic dispersion slope whose absolute value is less than 0.015 ps/nmnullkm, and an effective area greater than 35 nullm2, the relative effective area difference at a wavelength of 1550 nm between the positive chromatic dispersion optical fiber portions (Tnull) and the negative chromatic dispersion optical fiber portions (Tnull) being less than 7%, and each optical fiber portion (Tnull, Tnull) having bending losses at a wavelength of 1625 nm less than 0.1 dB for 100 turns with a diameter of 60 mm.

    • 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 null0 less than or equal to 1370 nm ; and an effective surface area greater than or equal to 50 nullm2. 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.
    • 在1300nm至1625nm的范围内呈现单线性行为的光纤,并且在1550nm的波长处具有5至11ps /(nm.km)的色散; 色散和色散斜率之间的比例从250 nm到370 nm; 相对于波长小于或等于0.14%/ nm的有效表面积的衍生物; 色散消除波长lambd0小于或等于1370nm; 并且有效表面积大于或等于50mum2。 所提出的标准限制了在宽波长范围内的光纤中非线性效应的变化,并限制待补偿的色散; 而且,光纤可以通过传统上用于阶梯折射率光纤的色散补偿光纤在传输系统中进行补偿。 有效表面积斜率的限制避免了单独处理传输系统中使用的各种波长的需要。
