(Telecompaper) Dutch operator KPN announced plans to start in September start a trial of fibre-optic network made from 90 percent recycled plastic. Only 10 percent would be made from new plastic, to manufacture the duct for the cable. The innovation is developed in collaboration with Allinq, Van Gelder Telecom, Prysmian Group and VolkerWessels Telecom. The trial is taking place in Buitenpost (Friesland) and Nijmegen Dukenburg. If results are positive, the innovation will be used for more fibre construction projects at KPN.
