Abstract:

In optical fiber overhead cables FRP-rods Fiber reinforced plastic- are used as strength members because of their low weight and their indifference to electromagnetic influence. First tests were carried out with E-glass-rods. After two years field tests we found a strength reduction of the FRP-rods of about 20 , caused by acid rain entering through some damages in the sheath. This strength reduction could be simulated in laboratory tests by soaking FRP-rods under bending strain in room temperature acid solutions. A comparison of E-, R- and S2-glass-rods at 0.5 elongation showed a 200 times longer durability for R- and S2-glass rods. Therefore optical overhead cables with an armouring of FRP-rods containing R- or S2-glass show significant improvements in performance. Author
