China debuts 10G broadband that downloads 4K films in under 20 seconds

China has taken a major leap in internet technology with the launch of its first 10G broadband network in Sunan County, Hebei Province, offering blazing-fast speeds that allow a full-length 4K movie to be downloaded in less than 20 seconds.

The ultra-speed network, launched on April 20, is the result of a collaboration between Huawei and China Unicom. It delivers download speeds of up to 9,834 Mbps and uploads reaching 1,008 Mbps, with an impressive latency as low as 3 milliseconds.

Powered by next-generation 50G Passive Optical Network (PON) technology, this advancement significantly enhances fiber-optic data transmission, opening doors to high-bandwidth applications like 8K video streaming, cloud computing, smart home integration, and immersive virtual and augmented reality experiences.

To put the leap in perspective: while a typical 1 Gbps connection may take around 10 minutes to download a 20 GB 4K movie, China’s new 10G infrastructure can handle it in just seconds.

This positions China ahead of global competitors such as the UAE and Qatar in commercial broadband capabilities and is expected to drive innovation across sectors like education, healthcare, and agriculture.

Huawei, a global telecom giant based in Shenzhen, and China Unicom, one of the country’s top three state-run telecom providers, spearheaded the project in a push to future-proof China’s digital ecosystem.
