Over the past two decades, the rapid growth in the number of Internet users and connected devices has dramatically boosted traffic to global cloud platforms and enterprise data centres. This surge has positioned data centres at the forefront of technological innovation. In recent years, the widespread adoption of AI technology has prompted data centres to evolve toward more efficient computing. As a result, data centre operators worldwide are striving to develop faster, denser, more cost-effective, and more energy-efficient infrastructures.

Where will R&D on next-generation mainstream optical fibres head?

During the 24th China International Optoelectronic Expo (CIOE 2023) , Yang Chen, Chief Scientist of Specialty Optical Fibres from Yangtze Optical Fibre and Cable Joint Stock Limited Company (YOFC) delivered a keynote speech titled "Specialty Optical Fibre Product Solutions for Optical Communication and Data Center Applications" at the Data Center Optical Interconnection Evolution Trends Forum. Yang emphasized, "As a leading enterprise in the optical communication industry, YOFC has leveraged its robust specialty optical fibre manufacturing technology and a whole-process management platform involving R&D, design, production, inspection, and testing to strengthen its presence in specialty optical fibres and cables. As a provider of solutions for pipeline transmission, optical amplification systems, data centers, optical transceivers, and special application scenarios, YOFC becomes an important contributor to the high-quality construction of communication networks and data centers."

Abstract: As the digital economy enters a new era with computing power as the core productivity, establishing reliable optical network connections is the key to the development of computing power services and applications. New optical fibres have become essential for building the next-generation computing infrastructure. The success of China Mobile Interprovincial Backbone Transmission Network 400G OTN New Technology Experimental Network Equipment Centralized Procurement Project marks an important milestone of China's basic telecom carrier in new technology deployment. This article will delve into the G.654.E fibre's properties and two mainstream optical fibre technologies relevant to the future evolution of computing power networks.

Photoelectric composite cable (or "hybrid optical and electrical cable") is a new method for interconnection with communication networks. It integrates copper wire with optical fibre transmission, simultaneously solving several problems related to broadband access, equipment electricity supply and signal transmission, and attracting great attention from telecommunications operators.
