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.
