The development concepts of CUBE-Net 3.0 and F5G Advanced are highly consistent. Their release also marked the beginning of a new chapter for the company that would feature intelligent integrated services. The system and architecture defined next-gen digital information infrastructure as "connectivity + sensing + computing + intelligence + security". Such infrastructure would better support digital economic and social development. In 2021, China Unicom proposed its CUBE-Net 3.0 network innovation system and a target architecture featuring computing and network integration to drive the transformation of traditional communications networks into next-generation digital infrastructure. China Unicom's all-optical network strategy opens a new chapter of intelligent integrated services At the end of 2022, ETSI had already completed F5G Advanced project initiation and started standard formulation. A general consensus on energy conservation is also driving optical fiber networks towards greener network architectures.īased on these requirements, ETSI released the F5G Advanced and Beyond White Paper in September 2022, which described the driving forces, scenarios, and key technologies of F5G Advanced and defined a host of future F5G objectives and capabilities. All-optical transmission networks will serve as infrastructure for Computing First Networks (CFN) and support ultra-low latency and extensive access. With factories and machines connected through optical fibers, optical networks will extend from the ICT industry to vertical industries. For example, in homes, VR/AR and smart home applications will increase in popularity, resulting in drastic increases in the number of devices. From 2025 to 2030, more new requirements and applications are expected to emerge, driving F5G evolution. In response, China's Ministry of Industry and Information Technology released the Action Plan for Coordinated Development of Double Gigabit Networks in March 2021 to promote the construction of F5G and gigabit optical networks, putting China's F5G industry on the fast track towards success.Īfter the F5G standards were officially released, research on F5G's future development paths began. ETSI's Industry Specification Group (ISG) F5G has nearly 100 members who have submitted more than 1,000 contributions, significantly advancing standardization for F5G industry applications.Įstablished at the end of 2021, the World Broadband Alliance (WBBA) has strengthened the industry's drive to translate F5G standards into industry applications. ETSI defined the technical architecture of this next-gen fixed network based on core technologies such as 10G PON + fiber to the room (FTTR) for broadband access, Wi-Fi 6, and single-wavelength 200G for optical transmission + optical cross-connect (OXC).į5G standards and the new vision quickly attracted wide attention across the industry.Īfter more than two years, F5G has achieved rapid development in both standards organizations and industry applications. In February 2020, ETSI released the Fifth Generation Fixed Network (F5G) standards and proposed the industry vision of Fiber to Everywhere and Everything.
