World's Fastest 1.2 Tbps Internet Network Now Operating In China


The world's fastest internet network is currently operating in China as it connects Beijing, Wuhan and Guangzhou. This 3000 kilometer long system is capable of transmitting data at a maximum speed of 1.2 Tbps (1200 Gbps) which is faster than the previous record of 400 Gbps held by the United States.

This internet system reaching a speed of 1.2 Tbps comes much earlier than the original prediction that it will only arrive by 2025. It is fast enough to allow 150 high-resolution movies to be downloaded in just 1 second. Even so, the world record for the fastest data transmission is still held by the Technical University of Denmark (DTU) and Chalmers University of Technology with a speed of 1.84 petabit/s (Pbps) but this is a test network and not for general use.

To realize it, collaboration is done between Tsinghua University, China Mobile, Huawei Technologies and Cernet Corporation. It took a decade to develop under the Future Internet Technology Infrastructure (FITI) program. Through FITI China wants to reduce dependence on outside technology as well as create a backbone network that can support 5G cellular networks.
