    Abstract: A light-diffusing optical fiber that provides a symmetric intensity distribution of forward and backward scattered light is described. The fiber includes a secondary coating that contains scattering centers. Control of the thickness of the secondary coating and concentration of scattering centers provides control over the distribution of scattered intensity. More symmetric distributions of scattered light intensity are realized by increasing the thickness of the secondary coating and/or the concentration of scattering centers in the secondary coating. Representative scattering centers include oxide nanoparticles.

    Abstract: Optical fibers having a mode field diameter at 1310 nm of at least 8.8 μm, wire mesh covered drum microbending losses at 1550 nm less than 0.03 dB/km, and a 2 m cutoff wavelength less than 1320 nm. The fibers may include a central core region, an inner cladding region, an outer cladding region, a primary coating with an in situ modulus less than 0.20 MPa and glass transition temperature less than −35° C., and a secondary coating with an in situ modulus greater than 1500 MPa. The fibers may further include a depressed index cladding region. The relative refractive index of the central core region may be greater than the relative refractive index of the outer cladding region may be greater than the relative refractive index of the inner cladding region. The fibers may be produced at draw speeds of 30 m/s or greater.

    Abstract: A fiber having a large effective area at 1550 nm of at least 130 μm2 and a wire mesh drum microbending loss of less than 0.4 dB/km at a wavelength of 1550 nm. The fibers may include a core, a cladding, and a coating. The core may include a central core region and a surrounding first core region. The cladding may include a depressed index inner cladding region and an outer cladding region. The coating may include a primary coating surrounding the cladding and a secondary coating surrounding the primary coating. The primary coating may be formed from a primary composition that may include an acrylate monomer or an N-vinyl amide monomer in combination with an acrylate oligomer, where the acrylate oligomer is present at 35 wt % to 55 wt %. The secondary coating may be formed from a secondary composition including one or more acrylate or diacrylate monomers and an acrylate or methacrylate oligomer, where the oligomer is present at 3 wt % or less.
