摘要： A dispersion compensating optical fiber is proposed for application in a wavelength optical signal transmission system. This dispersion compensating fiber has a W shaped refractive index profile, and has a first core layer, a second core layer formed around the outside of the first core layer, and a cladding layer made of substantially pure silica formed around the outside of the second core layer. The first core layer is doped with germanium, so that its refractive index s increased by a proportional refractive index difference of about 2%. The second core layer is uniformly doped with fluorine, so that its refractive index is decreased by a proportional refractive index difference of about 0.58%. The ratio of the outer radius of the second core layer to the outer radius of the first core layer is about 2.5. The wavelength dispersion slope is in the negative region, the dispersion is made to be high negative dispersion, and moreover the dispersion slope compensation ratio from a wavelength of 1530 nm to a wavelength of 1570 nm is made to be a value close to the perfect dispersion ratio and about 0.75 to 1.25 thereof.

摘要： An optical fiber for Raman amplification amplifies a signal light with a pumping light. A chromatic dispersion at a wavelength of 1,550 nm is in a range between −70 ps/nm/km and −30 ps/nm/km. Raman gain efficiency with a pumping light of 1,450 nm is equal to or more than 5 (W×km)−1. Nonlinear coefficient at the wavelength of 1,550 nm is equal to or less than 5.0×10−9 W−1. Zero-dispersion wavelength is neither at a wavelength of the signal light nor at a wavelength of the pumping light. Cut-off wavelength is equal to or less than the wavelength of the pumping light.
