DWDM Application scenarios of 400G technology
400G wavelength division technology is a bearer technology for the next decade. The total bandwidth of the 80*400G system reaches 32T. Considering the current traffic growth, network construction cost, and technology evolution, priority is given to the construction of 400GE port supporting networks in the backbone 163 hotspot areas and some metropolitan IP services, as well as the large bandwidth bearer scenarios for government and enterprise customers of East Data West Computing, multi-AZ connections between clouds, and intelligent computing:
Backbone communication network: From the current analysis of the growth of backbone 163 traffic and flow direction, the traffic between the major economic circles of Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong, Hong Kong and Macao, and Chengdu-Chongqing is relatively large, and the long-distance 400G QPSK technology can meet the construction of regional ROADM networks. Other areas of the backbone network can continue to use the original 100G ROADM network for traffic carrying. For some provincial trunks, PCS-16QAM technology can be considered, with a capacity of up to 48T and a lower cost than QPSK long-distance technology.

Metro communication network: Around the East Data West Computing hub node, the bandwidth growth in the provincial trunk and metropolitan area is expected. According to the expected traffic growth, 400G networks can be built in some provincial trunk hub nodes, East Data West Computing nodes, and metropolitan core nodes to meet the demand for bandwidth growth.
Cloud-to-cloud large bandwidth network: For highly reliable multi-AZ cloud-to-cloud and cloud-to-intelligence interconnection scenarios, the current 100G network has a total bandwidth of 8T, which cannot meet its business needs. Considering the occupied computer room, power consumption, operation and maintenance, and single bit cost, it is better to introduce 400G or higher speed to solve the requirements of large-scale data processing and storage for high-speed interconnection.
Four future development trends
The popularity of ChatGPT has promoted the construction of domestic intelligent computing centers. With the implementation of intelligent computing centers, intelligent computing applications will be launched quickly, and AI-generated videos will become easier and easier, further generating new traffic and promoting network connections. With the expansion of the application scale of 400G, the maturity of the industrial chain will further promote technological innovation and reduce manufacturing costs. In addition, with the development of silicon photonics technology, the future 400G wavelength division system will be more efficient, energy-saving, and less expensive.
