摘要:An optical fiber having both low macrobend loss and low microbend loss. Thefiber has a MAC number less than 7.0 and a zero dispersion wavelength less than 1450nm. 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 glasstransition temperature of less than −25° C. The secondary coating surrounds the primarycoating, and the secondary coating has a Young's modulus of greater than 1200 MPa. Themacrobend loss as measured by a 20 mm diameter bend test at 1550 nm is not morethan 5.0 dB/m. Optical fiber ribbon and optical fiber cable that include the optical fiber isalso disclosed.
