[Madrid, Spain, February 20, 2021] Huawei and Telefonica (Spain) have completed a pilot on wavelength division multiplexing (WDM) photonic meshes that support Telefonica’s Fusion IP Network. This pilot aims to strengthen the Fusion Network, by delivering greater quality and capacity in the face of emerging 5G and other new services.

The high single-wavelength 600G and 800G transmission speeds that Telefonica has achieved using Huawei OSN 9800 devices on the photonic mesh network in Madrid (spanning 47 km) is a prime example of this.

Juan José Marfil, the director of transport and IP connectivity at Telefonica, pointed out: “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. 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.”

Enhancing transmission speed is key to the development strategy of Telefonica. This is because these networks fundamentally carry all of the company’s services, whether it is for residential customers or large companies, and must also adapt to support the yearly 30% increase in traffic.

The use of 800G channels achieves full capacity for short-distance transmission. An example of this is using these new channels to transmit the equivalent of 500 one-hour HD quality movies over a pair of optical fibers in just a second.

Moreover, Telefonica will leverage the sustainability of its fast transmission technology to reduce energy consumption by 40% to 60% and become an industry pioneer for environmental sustainability.
