Abstract:
Small-radius coated optical fibers having large mode field diameter and low bending losses. The coated fiber may have an outer radius of 110 μm or less, while providing a mode field diameter of 9.0 μm or greater and a bending loss when wrapped about a 15 mm mandrel of 0.5 dB/km or less at wavelength of 1550 nm. The coated fiber may have a mode field diameter of 9.2 μm or greater and may have a bending loss at 1550 nm of 0.25 dB/km or less when wrapped about a 20 mm mandrel or a bending loss at 1550 nm of 0.02 dB/km or less when wrapped about a 30 mm mandrel.

Claim (Index 1):
A single-mode optical fiber comprising:\n a core, said core having an outer radius r 1  and a refractive index profile selected from the group consisting of a Gaussian profile, a super-Gaussian profile, and an \u03b1-profile with \u03b1=2; a cladding surrounding said core, said cladding having an outer radius r 4 ; a primary coating surrounding said cladding, said primary coating having an outer radius r 5 , said primary coating having an in situ modulus of 1.0 MPa or less and a glass transition temperature of less than \u221215\u00b0 C.; and a secondary coating surrounding said primary coating, said secondary coating having an outer radius r 6 , said secondary coating having an in situ modulus of 1200 MPa or greater; wherein said outer radius r 6  is 110 \u03bcm or less, said fiber has a mode field diameter of greater than 9 \u03bcm at 1310 nm, a cable cutoff wavelength of 1260 nm or less, a zero dispersion wavelength \u03bb 0  in the range 1300 nm\u2264\u03bb 0 \u22641324 nm, and said fiber exhibits a bend loss at a wavelength of 1550 nm, when turned about a mandrel having a diameter of 20 mm, of less than 0.5 dB/turn.
