Abstract
An optical fiber comprising: (i) a core having a refractive index profile; (ii) an annular cladding surrounding the core; (iii) a primary coating contacting and surrounding the cladding, the primary coating having an in situ modulus of less than 0.35 MPa and an in situ glass transition temperature of less than −35° C.; and (iv) a secondary coating surrounding the primary coating, the secondary coating having an in situ modulus of greater than 1200 MPa; wherein the refractive index profile of said core is constructed to provide an LP11 theoretical cutoff wavelength greater than 2.0 μm and an effective area greater than 110 microns2 at 1550 nm.
