First of all, there are obvious differences in the scenario requirements of optical networks. In the four typical application scenarios of data center interconnection, long-distance transmission, 5g forward transmission and government enterprise dedicated line, the demand for optical network in terms of equipment form, business characteristics, system capacity, operation and maintenance management is obviously different, which means that for equipment manufacturers, the idea of single product dominating the world is no longer feasible.
Secondly, open optical network has appeared in some fields, but the choice of technology route is quite different. Openness does not mean decoupling, nor is it the ultimate goal. It is a means to improve the efficiency of optical network management and the economy of network construction. Its core idea is how to turn optical network into a convenient service. From the perspective of network-as-a-service, the trend of open optical network is irreversible, but the specific technical route options are very flexible, which requires optical network users and equipment manufacturers to find the best balance from the perspective of technology.
Management and control has become the focus and key to improve network quality and efficiency. From the current international situation, the optical network will still be further developed and improved from the core devices, line transmission capacity, node scheduling, management and control system and other aspects. However, in view of the risk of industry chain fragmentation, the development and application of optical devices and other basic fields will slow down. Operators and other customers should start from the management and control system to improve the service adjustment of optical network Degree and management efficiency.
The trend of technology convergence is very obvious. Whether it is IP + optical collaboration or IP + optical convergence, flex-e or OSU, physical network extension or virtual network overlay, these convergence trends of network management, technical concepts and networking concepts are changing our customers' technology selection and usage habits, which is exactly what we should pay more attention to and think about.
