Huawei touts pair of 800-Gbps coherent transmission trials
Fresh off of announcing the development of an 800-Gbps coherent transmission module (see "Huawei unveils 800G tunable optical module"), Huawei has revealed that it has conducted trials of the technology with China Mobile (Zhejiang) and Turkcell. In both instances, Huawei is touting the applicability of 800G transmission to mobile network operators as well as those supporting big data and cloud networking.
In the China Mobile demonstration, the 800-Gbps transmission linked a pair of data centers 80 km apart. Huawei asserts the operator is “highly interested” in the technology and has agreed to collaborate further with the technology supplier. "We are delighted to have completed the first operator-based 800G trial with China Mobile (Zhejiang),” commented Simon Lu, President of Huawei's Transmission Network Domain. “This is a milestone in the global commercial use of Huawei's 800G solution. Huawei will continue investing in R&D to provide high-quality, reliable, and evolvable solutions while helping China Mobile (Zhejiang) achieve greater business success."
In Turkey, the demonstration also involved a pair of data centers, these in Instanbul. The distance between the two facilities was not revealed. The multi-rate trial also included 200G and 400G demonstrations. The latter included 1040 km of unregenerated transmission from Istanbul to Ankara.
"We continue our infrastructure investments to strengthen our existing technology and prepare our networks for 5G for superior user experience,” stated Gediz Sezgin, CTO of Turkcell. “In [the] 5G era, virtual reality applications, autonomous driving, and smart cities will be mainstays in the digital area. These technologies will pave the way for generating large revenues and transform our lives at large. High-speed data needs will be at their highest, and next- generation technologies such as remote surgery and robots will offer solutions to a wide variety of problems. We have been able to respond easily to rapidly increasing capacity needs through the 800G and 400G long-haul channels that we have deployed in our network. Turkcell will continue to lead the industry on new technologies in the future".
