Virtual Bookstore Citation Title IMPROVED RELIABILITY OF FIBER OPTIC OVERHEAD CABLES WITH AN APPLICATIONOF FRP (FIBER REINFORCED PLASTIC)-RODS WITH S2-GLASS Author(s) Hoevel,Albert ; Corporate Author(s) PHILIPS KOMMUNIKATIONS INDUSTRIE AG COLOGNE (GERMANY F R) Report Date 11/1/1986 Page Count 6 Abstract In optical fiber overhead cables FRP-rods (Fiber reinforced plastic-)are used as strength members because of their low weight and their indifferenceto 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 ofabout 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 durabilityfor R- and S2-glass rods. Therefore optical overhead cables with an armouring ofFRP-rods containing R- or S2-glass show significant improvements in performance.(Author) Out Of Print Prices are plus sales tax when purchased within New York State and shipping charges, if applicable
