China proposes to take the implementation of e-government and the construction of new smart cities as a starting point, and to use data centralization and sharing as a way to build a national integrated big data center, promoting technological integration, enterprise integration, and data integration to achieve cross-level and cross-regional integration, collaborative management and services across systems, departments, and enterprises. The digital economy based on the intelligent optical network will promote the development of smart cities. For example, in the financial industry, each 0.1 ms reduction in latency can increase the transaction volume by 10,000, and the transaction amount by more than 200 million yuan. Therefore, to promote the development of the digital economy, it is necessary to vigorously develop all-optical infrastructure and high-speed, high-capacity fiber optic technology.
High-speed, high-capacity fiber optic communication will become the backbone for emerging industries. Driven by multi-layered fiber optic communication networks, the demand for fiber optics in China's broadband computerization project continues to grow. The transmission distance of 400G+G.654.E in the DWDM system is expected to reach [a certain distance].A single-wavelength 90 Gbaud fiber reaches 1500 km, while G.652 fiber reaches 800-900 km. High-capacity communication technology based on low loss and large effective area will continue to develop. In accordance with the operator's plan for the design of the super 100G system and marine network, Shenzhen Aixton Cables Co., Ltd. leverages the entire optical communication industry chain, fully integrates optical network and fiber optic cable technology, and proposes the precise construction of a domestic optical cable backbone network based on the G.654.E. Fiber Optic Program.
High-performance transmission and autonomously controllable G.654.E fiber optic cable technology. Compared to G.652 fiber, the optical power of G.654.E fiber can be increased by approximately 2.0 dB. When used in complex environments, it can significantly improve 400G transmission performance and extend transmission distance without electrical relays. Fiberhome's G.654.E fiber optic cable, which has been part of China Telecom's fiber optic development for over 40 years, originated from the first practical fiber optic technology in China. It features a larger effective area, lower transmission loss, and stronger bending resistance. With intellectual property rights and control capabilities across the entire industry chain, this new, low-carbon, and environmentally friendly optical cable structure is ideal for 400G systems.
