Huawei says it has partnered with Telefónica (Spain) on a WDM mesh network pilot. The pilot investigated how such mesh networks, operating during the pilot with single-wavelength 600G and 800G transmission technology, might support Telefónica's Fusion IP Network initiative.
The mesh spanned 47 km and leveraged Huawei’s OSN 9800 platforms. The increase in transmission rates could help Telefónica keep abreast of traffic demands that have grown 39% annually. The service provider also could reduce energy consumption by 40% to 60% through use of the higher-speed technology and OSN 9800 systems in a mesh fashion.
"These pilots on the photonic meshes, in which signals are transmitted over optical channels without the need to switch to the electrical domain, are important milestones that build on the 400G speed that was achieved in 2019, also in Madrid,” explained Juan José Marfil, the director of transport and IP connectivity at Telefónica. “The goal is to begin implementing the 400G speed this year and subsequently optimize the Fusion IP Network to meet the needs for higher capacity and speed in view of the exponential growth of both connected devices and data transmission."
