Abstract
The present invention relates to a dispersion-compensating optical fiber which can transmit, with a low loss, light signals having a high power; and an optical transmission system including the same. This dispersion-compensating optical fiber is insured its single mode at a wavelength of 1.55 &mgr;m, and comprises, about the optical axis, at least a first core having a refractive index n1, a second core having a refractive index n2 (>n1), and a cladding having a refractive index n3 (<n2). Also, this dispersion-compensating optical fiber has a chromatic dispersion of −10 ps/nm/km or less at the wavelength of 1.55 &mgr;m, whereas the ratio 2a/2b of the outside diameter 2a of the first core with respect to the-outside diameter 2b of the second core is 0.05 or more.
