Abstract
In one embodiment, an optical fiber includes an inner core having a core refractive index delta and profile shape parameter α in the range of 1.8 to 2.6, including endpoints, and a cladding layer surrounding the inner core. The cladding layer includes an inner cladding segment having an inner refractive index delta, a trench segment having a trench refractive index delta, and an outer cladding segment having an outer refractive index delta. The optical fiber further includes a coating layer surrounding the cladding layer and having a thickness of less than 30 μm and a modulus greater than or equal to 0.5 GPa.
