Static Fatigue Transition In Optical Glass Fibres

Polymer coated optical glass fibres can exhibit under sever environmental conditions an accelerated static fatigue behaviour at long times under moderate stresses. To better understand the effect of coatings, a wide variety of coatings on optical glass fibres were tested for their effectiveness in inhibiting this accelerated fatigue behaviour. It was found that the most effective coatings in increasing the resistance of the fibre to accelerated fatigue were phenyl methy silicone and polyimide.
