摘要： An optical fiber having both low macrobend loss and low microbend loss. The fiber has a first inner cladding region having an outer radius r 2 > 8 micrometer and refractive index Δ 2 and a second outer cladding region surrounding the inner cladding region having refractive index Δ 4 , wherein Δ 1 > Δ 4 > Δ 2 . The difference between Δ 4 and Δ 2 is greater than 0.002 percent. The fiber exhibits a 22m cable cutoff less than or equal to 1260 nm, and r 1 /r 2 is greater or equal to 0.25.

摘要： A fiber having a large effective area at 1550 nm of at least 130 μm 2 and a wire mesh drum microbending loss of less than 0.4 dB/km at a wavelength of 1550 nm. The fibers include a core (14, 16), a cladding (18, 20), and a coating (22, 24). The core may include a central core region (14) and a surrounding first core region (16). The cladding may include a depressed index inner cladding region (18) and an outer cladding region (20). The coating includes a primary coating (22) of less than 190 μιη diameter surrounding and directly adjacent the cladding and having an in situ modulus of less than 0, 2 MPa, and a secondary coating (24) surrounding the primary coating and having an in situ modulus of more than 1,5 GPa. 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.
