The influence of wind load on a suspended fiber optic cable

Abstract

In the article the influence of precipitation and wind loads on a fiber optic cable suspended on the contact-line supports or power lines is considered. When the cable is subjected to the heaviest mode (ice with wind), the cable sags and returns (compressed) to the normal state according to the final modulus of elasticity, that is, there remains a residual elongation. We calculated the final sag at the maximum load. The mechanism of influence of precipitation and wind loads is shown in detail and the dependence of optic fiber attenuation on the wind effect is calculated.
