Abstract

The strength and fatigue data for Corning's single mode fiber (standard fiber) whose surface composition is 100% SiO₂ are compared with those of Corning's HFR fiber (developmental fiber) whose surface composition is predominantly SiO₂ but doped with a minor amount of another oxide. The modification of surface composition of the latter fiber results in a substantially higher fatigue constant n which is principally responsible for observed improvements in both the short-term and long-term reliability of HFR fiber relative to standard fiber. The strength data, both in tension and bending, in various environments are compared for short gage lengths of both types of fiber and found to be consistent with their compositional differences. The dynamic fatigue constant of 10 m long fibers, under tensile loading in 100% RH, is found to be 30% higher for HFR fiber than that for standard fiber, consistent with the measurements for bulk glasses of same compositions. Similarly, the static fatigue data in two point bending of both types of fiber in 80°C liquid water yield orders of magnitude longer lifetimes for HFR fiber than for standard fiber for a given strain level. The corresponding n value in bending is also higher for HFR fiber than for standard fiber. Thus, both the tensile and bending fatigue data are consistent with surface compositional differences pointing out another way for improving fiber reliability in service. Furthermore, the bending fatigue data for HFR fiber do not show the presence of a "knee" in failure time vs. flexural strain plot, unlike standard fiber.
