Abstract

The mechanical performance of two optical fibers samples (Sample A and Sample B), each from a different fiber manufacturer and colored by the same ultraviolet (UV) coloring process, was compared with that of a third sample, referred to as reference fiber. The mechanical performance was evaluated by fracture stress, strip force and pullout force and was correlated with the physical- chemical properties of the fiber coatings, as revealed by Fourier Transform Infrared Spectroscopy (FTIR) and Dynamic Mechanical Thermal Analysis (DMTA). The comparison of the three fibers revealed that fracture stress, strip force and pullout force were higher for the reference fiber than for the fibers of Sample A and B. Explanation for these observations were given in terms of the rubber and vitreous states of the fiber coatings, as well as the presence of additional phases in the coatings. It was also found that the mechanical performance of the fibers of Sample A and Sample B changed with the UV coloring process. These changes were observed to be different for each sample, as a result of the differences in internal coating structure. However, regardless of the changes, the mechanical performance of Sample A and B was always inferior to that of the reference fiber.
