Abstract: An optical fiber including: (1) a first outer cladding region including a no-slope portion establishing a 0% baseline (Δ0); (2) a core region surrounded by the first outer cladding region, the core region including (i) an outer radius (r1) from 4.0 μm to 6.5 μm and (ii) a maximum relative refractive index (Δ1max) from 0.3% to 0.6%, the core region exhibiting an α value of 5 or greater; and (3) a depressed index cladding region surrounding the core region and surrounded by the first outer cladding region, the depressed index cladding region including (i) an outer radius (r3) from 14 μm to 28 μm, (ii) a relative refractive index (Δ3) from −0.45% to −0.30%, and (iii) a trench volume (VT) from 65%-μm2 to 140%-μm2. The optical fiber exhibits lower LP01 bending loss than LP11 bending loss at operating wavelengths in the O- and C-bands.
