Abstract
A hybrid fiber which, at the operating wavelength, has a desirable fiber dispersion characteristic and a relatively large effective area is provided. Hybrid fibers are constructed in accordance with the principles of the invention by splicing together a fiber with a large effective area but typically unsatisfactory fiber dispersion characteristics to a fiber having excellent dispersion characteristics but a smaller effective area. The resulting hybrid fiber has an increased effective area and desirable fiber dispersion characteristics at the low-loss operating wavelength.
