China Telecom is the first in the world to deliver end-to-end 400G customer-grade private lines

On May 7, China Telecom officially announced that the first batch of 400G OTN premium private lines opened for leading Internet customers were officially delivered for use.

According to reports, with the support of ultra-large bandwidth, the customer's network connection in the data centers in Ningxia and Beijing-Tianjin-Hebei was upgraded from single-line single-wave 100G to single-wave 400G, realizing the connection between data centers. Collaborative operations such as "transportation, storage, and calculation" of massive user data. China Telecom stated that this is the world’s first end-to-end 400G customer-grade dedicated line delivered for commercial use. China Telecom’s OTN premium optical network started construction in 2019. It collaborated with communications manufacturers and adopted the industry’s mature single-wavelength 100G/200G wavelength division transmission technology to create a fully OTN-interconnected premium private network for government and enterprises, supporting capacity expansion.
