摘要： A single mode optical waveguide fiber having a relatively large effective area and low dispersion includes a segmented core having at least two segments each defining a radius, a refractive index profile and a relative refractive index percent. The waveguide fiber also includes a clad layer 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.

摘要： An optical transmission line which can restrict both wavelength distortion due to a non-linear phenomenon and wavelength distortion due to dispersion, and which is formed by series-connecting a first optical fiber (8) having a dispersion value of 6 to 14 ps/nm/km in a set wavelength band in a wavelength band of 1.5 mu m and a second optical fiber (9) having a dispersion value of -14 to -6 ps/nm/km in the above set wavelength band, the dispersion slopes of the first optical fiber (8) and the second optical fiber (9) having signs opposite to each other. Light transmitted from an optical transmitter (11) is shone on the first optical fiber, and light transmitted through the first optical fiber (8) is shone on the second optical fiber (9). Absolute value of dispersion in a wavelength band of 1.5 mu m of each optical fiber (8), (9) is set to be at least 6 ps/nm/km to restrict four-light-wave mixing, and the above each absolute value is set to be up to 14 ps/nm/km to restrict local dispersion, to thereby render almost zeroes dispersion values and dispersion slopes in the above set wavelength band over the entire optical transmission line.

摘要： The present invention relates to an optical fiber having a large positive dispersion in a wavelength band of 1.55 mu m in order to compensate for a negative dispersion inherent in an NZ-DSF in the wavelength band of 1.55 mu m. This optical fiber comprises a depressed cladding structure constituted by a core region; an inner cladding, disposed at the outer periphery of the core region, having a lower refractive index; and an outer cladding having a higher refractive index. In this optical fiber, the relative refractive index difference of the core region with respect to the outer cladding is at least 0.30 % but not greater than 0.50 %, and the relative refractive index difference of the inner cladding with respect to the outer cladding is at least -0.50 % but not greater than -0.02 %. Also, the optical fiber has a dispersion greater than 18ps/nm/km at a wavelength of 1.55 mu m, and an effective croos-sectional area Aeff of at least 70 mu m at the wavelength of 1.55 mu m.

摘要： An optical fiber having at least a structure for effectively suppressing the increase of microbend loss, preferable to dispersion-flattened optical fiber, dispersion-compensated optical fiber, and so forth, and adapted to compensate the single mode in the wavelength band used. Particularly, the optical fiber has a diameter of 140 mu m or more and consequently has a high rigidity. Since the increase of the microbend loss is effectively suppressed and the fiber diameter is below 200 mu m, the probability of rupture due to bending strain does not practically bring up any problem. The optical fiber has a larger mode field diameter, so that the optical energy density per unit cross section is small and nonlinear optical phenomena are effectively suppressed.
摘要翻译：至少具有抑制微弯损耗增加的结构的光纤，优选色散平坦化光纤，色散补偿光纤等，并适用于补偿所使用的波长带中的单模。特别地，光纤的直径为140μm以上，刚性高。由于微弯损耗的增加被有效地抑制，纤维直径小于200μm，所以弯曲应变引起的破裂的可能性实际上并不存在问题。光纤具有较大的模场直径，使得每单位截面的光能密度小，并且有效地抑制非线性光学现象。
