  • Publication number: 20070077016
    Abstract: An optical fiber having both low macrobend loss and low microbend loss. The fiber has a MAC number less than 7.0 and a zero dispersion wavelength less than 1450 nm. The optical fiber advantageously comprises a primary coating and a secondary coating. The primary coating has a Young's modulus of less than 1.0 MPa and a glass transition temperature of less than ?25° C. The secondary coating surrounds the primary coating, and the secondary coating has a Young's modulus of greater than 1200 MPa. The macrobend loss as measured by a 20 mm diameter bend test at 1550 nm is not more than 5.0 dB/m. Optical fiber ribbon and optical fiber cable that include the optical fiber is also disclosed.

  • Publication number: 20050286849
    Abstract: A dispersion compensation fiber for a moderate dispersion, low slope transmission fiber and transmission system including same. The dispersion compensating fiber has a refractive index profile having a central core with a core delta (?1), a moat surrounding the central core having a moat delta (?2), and a ring surrounding the moat having a positive ring delta (?3). The fiber's refractive index profile is selected to provide total dispersion less than ?80 at 1550 nm and less than ?90 ps/nm/km at 1600 nm, dispersion slope less than ?0.18 ps/nm2/km at 1550 and less than ?0.10 ps/nm2/km at 1600 nm, kappa between 250 and 450 at 1550 nm, and a kappa ratio (defined as kappa at 1600 nm/kappa at 1550 nm) of greater than 1.35.

  • Publication number: 20050094955
    Abstract: A dispersion compensating optical fiber includes a segmented core having a central core segment, a moat segment and a ring segment. The refractive index profile is selected to provide a total dispersion at 1550 nm of between ?114 and ?143 ps/nm/km, and a kappa, defined as the total dispersion at 1550 nm divided by the dispersion slope at 1550 nm, of between 96 and 150 nm. Optical transmission systems including the present invention dispersion compensating optical fiber optically coupled to a moderate dispersion single mode transmission fiber having dispersion at 1550 nm of between 5 and 14 ps/nm/km are also disclosed. Example transmission systems preferably exhibit residual dispersion over the C+L wavelength band (1525 to 1625 nm) of less than +/?20 ps/nm per 100 km of the moderate dispersion transmission fiber and less than +/?10 ps/nm per 100 km of the moderate dispersion transmission fiber over the C band (1525 to 1565 nm).
