Abstract

The microbending losses induced by hydrostatic pressure in double-coated optical fibers have been analyzed. The microbending loss is dominated by the lateral pressure in the glass fiber, which is affected by the material properties of the primary and secondary coatings and their thicknesses. In order to minimize the microbending loss induced by hydrostatic pressure, it is found that the thickness, Young´s modulus, and Poisson´s ratio of the secondary coating should be increased, but the Young´s modulus and Poisson´s ratio of the primary coating should be decreased.<>
