Paper Abstract

The transient microbending loss of a double-coated optical fiber, which is subjected to a time-dependent thermal loading, is analyzed and it is found that the transient microbending loss is a function of the temperature drop, thickness, and material properties of the primary and secondary coatings. The individual effect of the thickness, Young's modulus, Poisson's ratio, and the thermal expansion coefficient of the coating layers on the transient microbending loss of the optical fiber is also investigated. According to the numerical results, the thermally induced transient lateral pressure, and thus the transient microbending loss, in a double-coated optical fiber can be minimized by a suitable selection of the coating layers.
