ZTE, China Telecom partner on first commercial trial of 400G OTN cluster system


ZTE Corporation has partnered with the Shenzhen branch of China Telecom to deploy the industry’s first commercial trial of 400G OTN cluster system at multiple super-core nodes in the network, with each site supporting 128 service slots and 64T cross-connect capacity.

The system, which supports a maximum of 64-wavelength 400G and has a capacity more than three times that of a 100G system, can: facilitate ross-ring non-blocking scheduling of an enterprise private line; reduce the difficulty of network O&M; and help with the high-speed and stable operation of 5G transport networks, according to a statement from ZTE.

A statement from ZTE detailed how its OTN device, ZXONE 9700 – which features CE band – has been deployed for this solution, on which CE band is employed. The device supports a maximum network capacity of 25.6T, which is more than three times the capacity of a 100G system, “thereby fulfilling the demands of further network expansion and saving customer prior investment”.

The development is expected to further solidified ZTE’s growing market share, which according to data calculated by Dell'Oro Group, increased 2.4% in 2019. To date, ZTE has obtained 46 commercial 5G contracts in major markets, such as Europe, Asia Pacific, Middle East and Africa (MEA).
