Since the beginning of this year, my country has continuously accelerated the construction of new infrastructure represented by the pilot application of "10 Gigabit Optical Network" and 5G, and continued to consolidate the foundation for the development of the digital economy. Optical network is an important network foundation for the development of the digital economy, and plays an important role in driving GDP growth, improving innovation efficiency and production efficiency, and promoting the development of the digital economy.Ourcountry is leading the global development of optical networks, and the popularization of gigabit optical networks is accelerating. It is entering the "10 Gigabit Sailing" development stage, and key technologies and industries are developing in a coordinated manner.
New optical fibers and new optical fiber transmission systems are currently research hotspots and have the potential to support greater transmission capacity.Multi-core optical fibers have been deployed in multiple live network pilots; hollow-core optical fibers have many advantages such as low loss, large bandwidth, low nonlinearity, low latency, low dispersion and high dispersion flatness. Its preparation technology continues to mature and is expected to cause a disruptive change in optical fiber communications.
Driven by the new form of computing power network, optical networks have ushered in a major technological change marked by C6T+L6T 400G ultra-wide spectrum transmission. In 2024, China telecommunications operators has completed the 400G interconnection network construction project of the eight hubs of the national "East Data West Computing" project, and ushered in the first year of 400G commercial use. Talking about the interconnection needs of the intelligent computing center network across machine buildings, VCSEL technology based on hollow-core fiber is expected to achieve more than 2km single lane 200G signal transmission, which can effectively expand the application scenarios of VCSEL technology routes. However, VCSEL transmission based on hollow-core fiber is still facing technical challenges and needs to be continuously tackled.
From metropolitan areas to provincial trunks to national trunks, 400G is being widely built, and 800G/Tbps is coming.For the 800G/Tbps transmission rate that will be achieved in the future metropolitan area network, G.654.E fiber has significant advantages in extending the working distance without relays, and it is time to apply G.654.E fiber to the high bit rate transmission of metropolitan area networks. This decision comprehensively considers many factors such as the technical performance and cost-effectiveness of G.654.E optical fiber.
The surge in data and computing power in the AI era has accelerated the technological progress and industrial upgrading of the optical fiber and cable industry.the leap from gigabit to 10 gigabit in fixed networks, the generational evolution of mobile networks, the optical interconnection of data centers, and the construction of transoceanic communications urgently need new technologies, new optical fibers, and new networks. He introduced that Changfei i-Fibre series optical fibers have the characteristics of ultra-large capacity, ultra-low loss, ultra-low latency, synaesthesia and environmental friendliness, and are committed to providing strong infrastructure support for the development of the future intelligent world.
Looking around the world, people enjoy convenient life such as sharing, purchasing, downloading, and communicating in the digital field. For network operators, it means managing bandwidth that is growing almost exponentially to meet the growing global demand. Frederick Persson, executive vice president of Prysmian Digital Solutions, believes that operators are currently facing many challenges such as network congestion, labor shortages, administration, reliability and performance, and environmental restrictions.
The cyclical trend of the fiber optic cable industry is reversing and will return to a long-term trend. At a time when generative AI is booming, data centers have become the key infrastructure to support this technological leap. Corning has launched new optical fibers, new optical cables, new connectors and new customized integrated optical solutions to meet the infrastructure challenges brought about by the demand for artificial intelligence.
The global demand for optical fiber and cable market is expected to recover next year, and it is estimated to increase. This growth mainly depends on the rebound of the US market, the recovery of the European market and the stabilization of the Chinese market.
We believe that the construction of data centers based on generative artificial intelligence technology will drive the growth of demand for optical fiber and cable in this field.
