DEVELOPMENT OF THE CERNET NETWORK

In 2001, CERNET adopted DWDM / SDH technology to build a high-speed transmission network which at that time provided a total length of 12,000km and a network transmission capacity available of 16x2.5Gbps.

In 2006, CERNET completed the construction mission of Tenth Five Year Plan’s “211 Project”. The total length of CERNET optical fiber transmission network was expanded to 18,000 km, and the network transmission capacity was expanded to 40x10Gbps.

In 2013, the third phase of "211 Project" was completed. CERNET optical fiber transmission network was extended to 29 provinces, autonomous regions and municipalities in China, with a total length of 22,000 km and an increase in bandwidth to 40x100Gbps.

Today, CERNET now has over 30,000 km of trunk optical fiber and a 40x100G optical fiber transmission network that combine to provide transmission resources for the CERNET, CERNET2 and FITI backbone networks.

Over the past 20 years CERNET has built a world-class Network Center to deliver high-speed interconnection with domestic and international academic networks and public Internet.
