The project covers 21 ROADM sites in the middle and lower reaches of the Yangtze River in Hubei, Jiangxi, Anhui, Jiangsu, Zhejiang, and Shanghai, and uses Huawei's industry-leading CD-ROADM (wavelength independent, direction-independent dynamic optical add/drop multiplexers). ) Technology, it is easier to provide Full Mesh (all-interconnection) for the upper service network, direct route with one-hop wavelength, shortest path, lowest delay, and dynamic and rapid restoration. It can meet the low latency of services such as DC private line and financial major customer line. High performance requirements. The project can provide more than 300 100Gb/s circuits and 100% network recovery capacity in the current period. The technical level and scale of the network are among the highest in the world.
The domestic transmission network is moving towards the all-optical exchange era. With the constant increase of transmission bandwidth and the low latency demand brought by new services such as dedicated lines and 5G, the value of Full Mesh and all-optical exchange is self-evident.
Digital transformation brings important development opportunities. Network construction is shifting from technology-driven to commercial value-driven. The evolution path of technology is gradually returning to the nature of business. Huawei's comprehensive cloud network solution is centered on the realization of commercial value, and helps customers achieve business success by building an agile, intelligent, efficient, and open cloud network.
