Long-Haul Fiber

GTT long-haul fiber network covers Western and Central Europe, connecting key European cities. GTT owns the network from the duct level up, with a large multi-fiber cable already deployed and the capacity to deploy additional cable as and when demand dictates. GTT’s long-haul fiber service is based on a single fiber type: Corning® LEAF® (G.655). This ensures higher predictability, which is fundamental for optimal network design.
