The optical fiber is mainly composed of silica glass and has a core region including a center of an optical axis, a depressed region surrounding the core region, a ring region surrounding the depressed region, and a cladding region surrounding the ring region and doped with F. As compared with the refractive index of pure silica glass, a relative refractive index difference of the core region is greater than 2% but less than 3%, a relative refractive index difference of the depressed region is −1% or more but −0.5% or less, a relative refractive index difference of the ring region is 0.01% or more but 0.24% or less, and a relative refractive index difference of the cladding region is −0.3% or more but −0.1% or less. The FOM at the wavelength of 1550 nm is 250 ps/nm/dB or more.

摘要： An optical fiber cable including first, second and third optical fibers connected together so that light traveling through the cable travels through the first optical fiber, then through the second optical fiber and then through the third optical fiber. The second optical fiber has a negative dispersion value. The first and third optical fibers each have a positive dispersion value. The cable optically connects together two optical repeater stations, or an optical repeater station and an end station. Lengths of the first, second and third optical fibers are set so that loss in the first, second and third optical fibers of light transmitted through the first, second and third optical fibers is compensated by Raman amplification occurring in the first, second and third optical fibers.
