Patent ID: 6907171

Claim:
An optical fiber composite comprising: (a) a first optical fiber having a first chromatic dispersion, D 1 , at the wavelength of a signal-carrying lightwave; (b) a second optical fiber that: (b1) has a second chromatic dispersion, D 2 , at the wavelength of the signal-carrying lightwave, the second chromatic dispersion having the sign opposite to that of D 1 ; and (b2) is spliced to one end of the first optical fiber; and (c) a third optical fiber that: (c1) has a chromatic dispersion, wherein the difference between the chromatic dispersion and the first chromatic dispersion being not more than 3 ps/mn/km; (c2) is shorter than the first optical fiber; and (c3) is spliced to the free end of the second optical fiber.
