Abstract
The optical fiber disclosed has a glass fiber including a core and a cladding. The core comprises silica glass doped with chlorine and having an outer radius rbetween 3.0 microns and 10.0 microns. The cladding has an outer radius rnot less than 50.0 microns. A primary coating surrounding the cladding has a thickness (r-r) between 5.0 microns and 20.0 microns, and an in situ modulus less than 0.30 MPa. A secondary coating surrounding the primary coating has a thickness (r-r) between 8.0 microns and 30.0 microns, a Young's modulus greater than 1500 MPa, and a normalized puncture load greater than 3.6×10g/micron. The optical fiber has a 22-meter cable cutoff wavelength less than 1530 nm, an attenuation at 1550 nm of less than 0.17 dB/km, and a bending loss at 1550 nm of less than 3.0 dB/turn.
