The system supports a maximum of 64-wavelength 400G, and its capacity is 3.2 times of that of a 100G system. It can effectively satisfy the requirements for cross-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.

Further, the 400G system satisfies the non-blocking scheduling requirements of a large number of small-granularity services brought by SDH equipment phasing out, effectively enabling high-speed transport of 5G, gigabit broadband and enterprise private line services, significantly reducing O&M difficulty and saving network O&M costs for customers.

ZTE has deployed its flagship OTN device ZXONE 9700 for this system, on which CE band is employed. The device supports a maximum network capacity of 25.6T, which is 3.2 times the capacity of a 100G system, thereby fulfilling the demands of further network expansion and saving customer prior investment.

In addition, the project is also deployed with a 32-degree ROADM optical-layer architecture, in a bid to further improve transport efficiency. The architecture allows MAN flatness and full-Mesh multi-directional connections, and supports one-hop transmission, thus decreasing OTN service transport latency, improving user experience and alleviating bandwidth pressure on MAN core nodes.

According to the latest report by Dell’Oro Group released in March 2020, the market share of ZTE optical network devices increased by 2.4% in 2019, becoming one of the two vendors with the largest increase. Moreover, Omdia showed that ZTE ranked second in the global OTN switching market in 2019.
