OPTICAL FIBER AND OPTICAL COMMUNICATION SYSTEM COMPRISING THE SAME

摘要

An optical fiber having a structure suitable for long-distance optical communication and an optical transmission line comprising the same. The optical fiber comprises a core region extending along a predetermined axis and a clad region surrounding the core region. The optical fiber has characteristics at the 1.55 mu m wavelength, such as an effective cross section of more than 110 mu m<2>, a dispersion of 18 to 23 ps/nm/km, and a dispersion slope of 0.058 to 0.066 ps/nm<2>/km.
