\tPRESS RELEASE: ZTE Corporation in partnership with the Guangdong branch of China Mobile, has taken the lead in completing the single-carrier 400G pilot tests of multiple scenarios in the existing network, including OXC point-to-point, OXC pass-through, FOADM, and OLP protection tests.<\/p>\n

In the tests, ZTE has achieved ultra-high-speed long-distance transmission on the provincial backbone network with a total length of 683 km, based on G.652.D optical fibers. It fully verifies that the single-carrier 400G has been commercial ready, and laid a foundation for the deployment of 400G on the provincial backbone networks of China Mobile.<\/p>\n

With the implementation of China’s “east-data-west-computing” project, computing power has become the hot topic of the industry. Currently, router ports in IDC equipment rooms are being upgraded to 400GE while data centers in Guangdong Province are being moved to tier-2 and tier-3 cities and the networks are turning flat. Basic networks focus more on service experience than network performance, and pose higher requirements for bandwidth, latency and transmission distance of transport networks.<\/p>\n

Therefore, in application scenarios of the existing network, how to build an OXC all-optical network based on single-carrier 400G has become the network evolution goal of China Mobile. The all-optical network is aimed to dynamically perceive the service traffic, flow demands and changes in the computing power network, and guarantee computing and network synergy, timely response, and end-to-end services, so as to speed up service transmission without reducing the distance.<\/p>\n

ZTE\u00a0has\u00a0provided the\u00a0ZXONE 19700 electrical cross-connect subracks\u00a0based on the\u00a032-degree\u00a0OXC system with\u00a0a single-slot bandwidth of up to 1T at the nodes between Guangzhou\u00a0and Zhanjiang in the provincial backbone network of Guangdong Mobile. Employing the 400G PS-16QAM modulation, ZTE has completed the pilot tests in practical application scenarios such as provincial backbone OXC, FOADM, and OLP, based on G.652.D optical fibers with a total length of 683 km. The test items include\u00a0the impact of OXC on system performance\u00a0in comparison with FOADM, OLP insertion loss, and the impact of OXC optical pass-through on system performance, and\u00a0the comparison between the transmission performance\u00a0of 400G and 200G. ZTE has passed all the\u00a0tests in merely 13 days. The test results show that the Guangzhou-Zhanjiang system of China Mobile can implement service provisioning without regeneration based on single-carrier 400G.<\/p>\n

During the multi-level OXC pass-through in the existing network, the\u00a0system\u00a0OSNR\u00a0has not\u00a0degraded obviously and\u00a0so\u00a0meet the service transmission requirements. At the same time, the 400G system can operate stably at both the FOADM and OXC optical layers, and has the OLP (Optical Line Protection) and APO\u00a0(Automatic Power Optimization)\u00a0functions. Therefore, the 400G system is ready for commercial use.<\/p>\n

Moving forward, China Mobile and ZTE will continue with the\u00a0transmission performance tests\u00a0of 400G QPSK\u00a0in multiple application scenarios in\u00a0the existing network\u00a0to\u00a0provide more choices for long-distance transmission\u00a0of 400G on backbone networks.<\/p>\n\n
