Title:
分散補償ファイバ
Document Type and Number:
Japanese Patent JP3912009
Kind Code:
B2
Abstract:
The dispersion-compensating fiber according to the present invention is an optical fiber having a structure which, when constituting an optical transmission line together with a single-mode optical fiber having a zero-dispersion wavelength near 1.3 mu m, is capable of improving transmission characteristics of the whole optical transmission line and allowing the dispersion to be compensated for efficiently and the size thereof to become smaller, and has a structure for improving the total dispersion slope of the optical transmission line while in a state fully compensating for the dispersion of the single-mode optical fiber. This dispersion-compensating fiber has a triple cladding structure having a first cladding, a second cladding, and a third cladding which are successively provided on the outer periphery of a core, and, in a state where the relative refractive index differences in its individual regions and outer diameters thereof are optimized so as to compensate for the dispersion of the single-mode optical fiber, realizes an optical transmission system having a favorable total dispersion slope.
