On November 13, a press conference for the opening of the world's first 1.2Tbps ultra-high-speed Internet trunk channel was held at Tsinghua University.This channel connects Beijing, Wuhan and Guangzhou with a total length of more than 3,000 kilometers., opened on July 31, 2023, operates smoothly and reliably, passed various experimental tests, and reached the design indicators.
It was jointly developed by Tsinghua University, China Mobile, Huawei, and Xaar, and is based on my country's independently developed next-generation Internet core router 1.2TIPv6 interface, 3x400G ultra-high-speed multi-optical aggregation and other key core technologies.
Hardware, systems, and software are all domestically produced and independently controllable, and are at the leading level in the world.
1.2T converted into popular expression is1.2 million Gigabit, which is equivalent to 1,200 times that of a home Gigabit network, and can transmit 150 high-definition movies in one second.
Currently in the Internet field, 400G backbone channel technology has just been put into commercial use. It was generally predicted that the Tb level will not appear until around 2025. my country has achieved this leap more than two years in advance.
According to data from the Ministry of Industry and Information Technology, as of the end of September 2023, my country has approximately 63.097 million kilometers of optical cable lines, including approximately 1.124 million kilometers of long-distance optical cable lines, and 1.12 billion Internet broadband access ports, including 1.08 billion FTTH/FTTO optical fiber access ports.
The total number of Internet broadband access users is 629.838 million, of which 144.633 million are Gigabit and above, with a penetration rate of 23.0%.
