Optical Fiber Corrosion: Coating Contribution to Zero-Stress Aging

Abstract

Critical mechanical properties of optical fibers are high strength, small strength variability, high fatigue resistance and high aging resistance. The effect of zero-stress aging on optical fibers is of considerable importance in cables and in splice cases because fibers can encounter high humidity or water which can degrade their strength. These aged fibers may be stressed later during routine maintenance or other field craft activity. The effect of aging on the mechanical reliability of optical fiber is therefore an important consideration in any system design.
