Abstract:
1. A bend-insensitive optical fiber, comprising: a single-mode glass fiber comprising (i) a central core surrounded by an outer optical cladding, the central core having a radius r a substantially cured primary coating surrounding the single-mode glass fiber, the substantially cured primary coating possessing (i) an in situ modulus of less than about 0.65 MPa and (ii) a glass transition temperature of less than about −50° C.; wherein, at a wavelength of 1310 nanometers, the optical fiber has a nominal mode field diameter (MFD) between 8.6 microns and 9.5 microns; wherein, at a wavelength of 1550 nanometers, the optical fiber has bending losses less than 0.15 dB/turn for a radius of curvature of 5 millimeters; and wherein the optical fiber has a cable cut-off wavelength (λ
