LARGE EFFECTIVE AREA FIBER WITH LOW BENDING LOSSES

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...

More Information
Summary: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.
