China Telecom and TransTeleCom, one of the leading Russian telecommunications companies, have developed the first transit telecommunication route connecting China and Europe based on 100G ULH (Ultra Long Haul) DWDM technology. As part of the project, the companies have constructed a new 100Gbps gateway interface on the border between the two countries, the Chinese city of Manzhouli and in the Russian city of Zabaikalsk. China Telecom is committed to building the new Digital Silk Road that connects Asia and Europe. From the Information Highway between Asia and Europe which launched as early as 2013, to the latest 100G Asia-Europe terrestrial cable service in 2017, China Telecom has mapped out a wide information network that runs from China to Russia, Belarus, Ukraine and Central Asia countries, as well as reaches the Atlantic through Switzerland, Germany and the U.K. This high-quality network features large bandwidth, multiple routes, low latency and great controllability.
