China Just Switched on World’s First 10G Internet Network

China has activated what it describes as the world’s first commercial 10-Gigabit (10G) broadband network in Sunan County, Hebei Province. The project is a joint undertaking by China Unicom and Huawei.

The system is based on 50G Passive Optical Network (PON) technology, which increases data transfer capacity over existing fiber-optic lines. Initial tests recorded peak download speeds of 9,834 Mbps, upload speeds of 1,008 Mbps, and latency as low as 3 milliseconds significantly faster than typical 1G broadband services.

The network can support large data transfers and bandwidth-intensive tasks such as 8K video streaming, virtual reality environments, and cloud-based applications. For example, a 20GB file could be downloaded in under 20 seconds.

Authorities indicated that this deployment would serve as a reference point for future implementation in other areas. Nationwide expansion is expected to depend on technical readiness and user demand.

Although several countries — including South Korea, the United Arab Emirates, and Qatar — have invested in next-generation broadband, China is the first to officially launch a 10G service for public access.

The higher-speed network could be applied in areas that require stable, low-latency connections, such as distance learning, digital healthcare, remote operations in agriculture, and industrial systems.

According to Huawei, adopting 50G PON made it possible to increase performance without the need to replace existing infrastructure.

This deployment is part of broader efforts in China to develop digital infrastructure and improve internet access in line with growing demands from connected devices and data services.
