Relationship between the characteristics of UV-cured acrylate resin and the dynamic fatigue value of optical fibers

摘要

We Investigated the relationship between the dynamic fatigue value and various properties of UV-cured urethane acrylate resin coating for 0.25 optical fibers. The effect of pH value of the primary coating, moisture permeability, and thickness of the secondary coating on the fatigue properties, especially dynamic n value, were evaluated. The effect of pH on the zero-stress aging of optical fibers was also investigated.
