Wu Hequan: Optical access networks are facing challenges of insufficient uplink bandwidth and lack of applications. News on September 26 (Shuiyi) Recently, at the 10 Gigabit Optical Network Innovation Forum of the ICT China 2025 Series Events , Wu Hequan, former vice president of the Chinese Academy of Engineering, said that the new generation of new infrastructure represented by 10 Gigabit optical networks is not only the network base to support economic and social development, but also the key to seizing the commanding heights of future development. With the gradual maturity and pilot application of 10G optical network technology, it will not only bring a higher-speed, more convenient, and smarter network service experience to the people, but will also further empower industrial production, intelligent manufacturing, park management, etc., and press the accelerator button for promoting new industrialization and digital transformation in various economic and social fields. Regarding the development of 10G optical network, Wu Hequan suggested that there should be systematic thinking and work together to build an innovative, open, inclusive and win-win 10G optical network industry ecosystem. First, strengthen collaborative innovation and promote industrial upgrading. Efforts should be made to build a full chain from basic research and technological research to product development and application services, promote the deep integration of government, industry, academia, research and application, form an innovation ecosystem with joint research and complementary advantages, jointly break through industrial shortcomings and weaknesses, and improve the resilience and security level of industrial and supply chains. Wu Hequan said that the current penetration rate of 100M broadband network in my country exceeds 95%, and the Gigabit penetration rate exceeds 33%, but the uplink bandwidth is generally 40M. In the past, small and medium-sized enterprises adopted the home broadband model to save a lot of costs of leasing operator dedicated lines. Now, with the rapid development of artificial intelligence, 40M uplink bandwidth is difficult to meet demand. At the same time, due to data security considerations, small and medium-sized enterprises adopt the storage and calculation separation model. After performing some calculations at the headquarters, the intermediate parameters are sent to the cloud for reasoning, which puts forward higher requirements for the certainty, low latency and high reliability of uplink bandwidth. In addition, existing optical access networks lack differentiated service capabilities for user needs. It is not economical or reasonable to increase the speed of each user to Gigabit or even 10 Gigabit. How to provide broadband services on demand has become an important challenge for optical network innovation. Second, deepen integrated applications and empower industry transformation. It is necessary to actively meet the digital transformation needs of key industries of the national economy such as industry, energy, transportation, medical care, and education, use pilots as the starting point, and combine innovation competitions and other activities to support the creation of scenario-based and customized excellent innovation cases of 10G optical network, and promote the technological dividend of 10G optical network to empower thousands of industries. Wu Hequan pointed out that although the 100M penetration rate exceeds 95% and the Gigabit penetration rate exceeds 33%, the traffic growth brought about is not commensurate. According to statistics, the national broadband network traffic increased by 17% last year. Moving forward to 10 Gigabit, bandwidth is available. If traffic and applications cannot keep up, operators' enthusiasm for construction will be affected. This problem not only needs to be solved at the transmission level, but also requires comprehensive consideration of access supporting capabilities. The current metropolitan area network convergence ratio is about 1:10. If all users use it at the same time during busy hours, the network support capacity will be insufficient, so edge computing deployment needs to be increased. It is worth noting that currently only one-third of my country's 10G-PON ports are used, the optical access network supporting facilities are not reasonable, and node construction still needs to be strengthened. Third, expand international cooperation and jointly build a development pattern. Adhering to the concept of open cooperation, we actively participate in the formulation of global standards for 10 Gigabit optical network technology, actively share Chinese wisdom and Chinese solutions, work with other countries around the world to promote the sharing of next-generation information and communication technologies such as 10 Gigabit optical network, and contribute to building a community with a shared future in cyberspace
