Huawei has announced that it has completed two 800G coherent trials on live networks. One is with Turkcell and the other with China Mobile Zhejiang. The announcement follows Huawei’s launch of a 800G tunable optical module at the end of February 2020.

The Turkcell trial took place between two data centres in Istanbul using Huawei’s ultra-high-speed service processing boards which support the programmable and flexible adjustment of multiple modulation formats ranging from 200G to 800G. By using channel-matched shaping (CMS) technology, the latest Faster Than Nyquist (FTN) algorithm system and AI neuron function module, the system can monitor complex link environments on live networks in real time to quickly and automatically learn and optimise network transmission performance. This ensures optimal spectral efficiency and transmission performance while achieving the single-fibre capacity of 48 Tbps. The trial also confirmed the 400G ultra-long-haul transmission capacity of the live network, which can implement 1040 km of unregenerated transmission from Istanbul to Ankara.

Gediz Sezgin, CTO of Turkcell (pictured) said, “We continue our infrastructure investments to strengthen our existing technology and prepare our networks for 5G for superior user experience. In the 5G-era, virtual reality applications, autonomous driving, and smart cities will be mainstays in the digital area.”

Simon Lu, President of Huawei’s Transmission Network Domain, said: “We are happy to work with Turkcell and complete the 800G WDM trial on the live network, which cements Huawei’s leadership in the ultra-high-speed optical transmission field. Huawei will continue to maintain its strategic investment and innovation in high-speed optical transmission and provide high-quality, reliable, and evolvable solutions for customers around the globe.”

A few days previously, Huawei announced that China Mobile (Zhejiang) had trialled Huawei’s 800G tunable ultra-high-speed optical module, which supports bandwidth and wavelength spacing adjustment and enables up to 48 Tbps per-fibre capacity, which is six times the capacity of traditional 100G networks and can support one million concurrent 4K users. Two data centres at a distance of 80 km were used in this trial which successfully confirmed that the 800G solution performed and functioned as expected, indicating its upcoming commercial release.
