Abstract
A single-mode optical fiber possesses, at a wavelength of 1550 nanometers, an effective area greater than about 90 pm2 without degradation of the optical fiber's other optical parameters. The single-mode optical fiber includes a central core, a first intermediate cladding, a second intermediate cladding, and an outer cladding. The optical fiber also has a cable cut-off wavelength of less than 1260 nanometers. Additionally, at a wavelength of 1310 nanometers, the optical fiber possesses a mode field diameter of between about 8.6 microns and 9.5 microns. Furthermore, the optical fiber possesses a zero chromatic dispersion wavelength of between about 1300 nanometers and 1324 nanometers and, at the zero chromatic dispersion wavelength, a dispersion slope of less than 0.092 ps/(nm2″km).
