Abstract: Optical fibers having a mode field diameter at 1310 nm of at least 8.8 μm, wire mesh covered drum microbending losses at 1550 nm less than 0.03 dB/km, and a 2 m cutoff wavelength less than 1320 nm. The fibers may include a central core region, an inner cladding region, an outer cladding region, a primary coating with an in situ modulus less than 0.20 MPa and glass transition temperature less than −35° C., and a secondary coating with an in situ modulus greater than 1500 MPa. The fibers may further include a depressed index cladding region. The relative refractive index of the central core region may be greater than the relative refractive index of the outer cladding region may be greater than the relative refractive index of the inner cladding region. The fibers may be produced at draw speeds of 30 m/s or greater.

Abstract: A method for measuring a mechanical property of a coating on an optical fiber may include collecting Brillouin frequency shift data of the coating on the optical fiber, and determining the mechanical property of the coating by comparing the collected Brillouin frequency shift data with correlation data that may include a set of collected sample Brillouin frequency shift data and a set of collected sample mechanical property data of a plurality of sample materials. The sample materials may include a substantially identical sample composition including one or more curable polymers, be prepared with varying processing conditions, and have different mechanical property values. The coating on the optical fiber may include a material composition substantially identical to the sample materials composition. The set of collected sample Brillouin frequency shift data may be correlated with the set of collected sample mechanical property data to determine a quantitative relationship therebetween.
