AI meets light, enabling new technologies to land

Regarding to the key technologies of optical networks in the future, Li Yunbo, a professor-level senior engineer at China Mobile Research Institute, pointed out that the continuous expansion of optical networks and exponential growth in complexity have led to a doubling of operation and maintenance costs, and operators are facing cost and efficiency challenges. Intelligent sensing technology, cloud-ground collaborative full-stack AI technology, intelligent analysis and prediction technology are the keys to realizing the autonomy and self-healing ability of optical networks. When AI meets light, it can effectively solve the cost and efficiency problems caused by preventive, complex, and repetitive tasks in network operation and maintenance. The organic integration of AI and optical networks will bring continuous innovation in optical network services, experience, and operations. In March, China Mobile also proposed an "autonomous driving network", the core of which is to introduce AI technology to create an autonomous and self-healing network to improve the efficiency of operation and maintenance.

Regarding the application of AI in optical networks, Zhang He, director of the Transmission Office of China Unicom's Network Technology Research Center, pointed out that breakthroughs in key technologies such as data twins and artificial intelligence have fundamentally changed the future of optical networks. At present, there are still considerable challenges in the practice of AI-enabled optical networks. For this reason, China Unicom will gradually advance its application in four major areas. The first application is an intent-based optical network. The intention engine greatly simplifies the business debugging process, shortens the business debugging cycle and improves operational efficiency. At the same time, it can actively sense network changes to ensure that the SLA of the business can always be guaranteed. The second application is intelligent alarm analysis, which uses machine learning algorithms to mine multi-dimensional historical data (such as historical alarms, topology, resources, performance, etc.). Finally, based on the model analysis results, it provides fault repair suggestions and automatically triggers scheduling actions. The third application is the intelligent analysis of optical channel health. By collecting historical performance values, alarms and operation logs from the network and using classification algorithms to build models, the optical channel’s health and sub-health status can be classified, which can help operators take the initiative, predictively understand the state of the optical channel. The fourth application is intelligent routing optimization. Through the three steps of traffic prediction, path optimization and network upgrade, the network can have abnormal traffic and timely warning, automatic re-routing planning, and automatically trigger the network planning module to carry out online network upgrade planning when network resources are insufficient.

High-speed intelligent connection, integrating key new technologies
Talking about the innovation of the future optical network in the three dimensions of flow, distance and delay, Cao Quan, the technical director of Fisilink, said that the application of coherent technology is continuously expanding, and it is necessary for high capacity, long distance transmission, low cost and low power consumption. System requirements for optical devices. However, current coherent optical devices are faced with many challenges such as limited baud rate in high-end applications and slow cost reduction in DCI scenarios. How to deal with these challenges, Fisilink believes that it is necessary to firmly grasp the three core technical issues of optoelectronic integrated packaging, photoelectric collaborative design and flexible algorithm control in order to promote the further evolution of coherent technology and meet the continuous application requirements of the system.

Xu Anran, Technical Director of FiberHome’s pre-research technology, introduced the two national key R&D projects currently led by FiberHome and their research results, including high-performance optical transmission technology, highly integrated silicon optical transceiver chip devices, high-performance highly integrated ultra-100G optical transmission equipment and network virtualization technology for the integration of computing, storage, and transmission resources. Among them, in terms of silicon optical new chips and devices, the project research team developed the world's first 4x200Gb/s silicon optical modulator based on self-developed high-speed silicon optical chips. At present, FiberHome has achieved autonomy in the field of self-developed chips and devices. In the field of cloud-network integration technology, FiberHome is conducting research on the theoretical system of network virtualization. In the future, it will make innovations and breakthroughs in the theoretical system of cloud-network resource integration and new platform equipment supporting cloud-network resource integration.
