With the introduction of SDN, AI, and other new technologies, optical network is given a brand-new definition. Especially in the 5G era, the network architecture is more complex. Due to the increasing functions and performance, and the massive data traffic and the emergency of new business models, making the requirements for optical network bearing capacity are getting increasingly high. The industry needs to achieve intelligent management, ultimate experience, and flexible openness of optical networks by means of artificial intelligence to achieve the goal of improving user experience and reducing operating costs. However, to build automotive optical networks, realize the intelligent evolution of optical network to all-optical base, and break through bottlenecks such as cost, technology, and application scenarios, the industry needs collaborative innovation.
