Downloading a full 4K movie in less than three seconds is no longer science fiction; it is happening right now in China.
Residents and businesses in Xiong’an New Area are already connected to the world’s first large-scale commercial 10 Gbps broadband network, launched in April 2025 by China Unicom in partnership with Huawei’s cutting-edge 50G-PON technology. Real-world tests consistently achieve download speeds of over 9.8 Gbps, uploads of around 1 Gbps, and latency as low as 3 milliseconds. That performance turns a 50 GB Blu-ray file into something you can pull down faster than it takes to brew coffee.
The network stands apart because it was built from the ground up for the future. While Singapore, South Korea, and Japan initially offered limited 10 Gbps plans, these plans were based on older XGS-PON systems and served only select buildings or customers. Xiong’an’s rollout blankets an entire new city planned around digital infrastructure, marking the first actual city-wide deployment of next-generation passive optical network technology.
At its heart is the 50G-PON standard (ITU-T G.9804 series), which Huawei pioneered with significant contributions from China Mobile, Orange, and other organizations. Huawei demonstrated the world’s first working 50G-PON prototype in 2019 and has since led the standardization and commercialization efforts, making this the first large-scale deployment of the technology anywhere on the planet. Operators can overlay it on existing fiber without disrupting current users, creating a transparent and cost-effective upgrade path all the way to 50 Gbps symmetric in the coming years.
Daily life on this network already feels like the future. Cloud gaming is flawless, with 8K and 16K video streams available without buffering. Massive AI models can be downloaded in a matter of moments. Autonomous vehicles, smart factories, and city-wide sensor systems finally have the ultra-low-latency backbone they need. While much of the world is still celebrating 1 Gbps as “fast,” Xiong’an residents are living in a 10 Gbps reality.
This milestone quietly redraws the global technology landscape. When one country demonstrates that 10 Gbps at a city scale is not only technically possible but also already profitable and practical, every other nation suddenly finds itself in catch-up mode. The new digital divide is no longer just about having internet access; it is about having internet that is fast enough to power the innovations of the next decade.
China just raised the bar to a height others will spend years trying to reach. The true multi-gigabit era has officially begun, and it started in Xiong’an.
