Abstract
An optical fiber composite that can easily have a desired mean transmission property as a whole even after a length of optical fiber is cut off from one end or both ends, a cable comprising the composites, and methods for producing the composite and cable. An optical fiber compositeis produced by splicing a first optical fiber, a second optical fiber, and a third optical fiberin this order. The first optical fiberand the third optical fibereach have a first chromatic dispersion, D, at the wavelength of a signal-carrying lightwave. The second optical fiberhas a second chromatic dispersion, D, at the wavelength of the signal-carrying lightwave. The third optical fiber has a length, L, shorter than the length, L, of the first optical fiber. It is desirable that the ratio L/Lbe at most 0.1.
