China reached a significant milestone in the evolution of telecommunications infrastructure by establishing the world’s first 800G hollow-core fibre transmission test network in Shenzhen-Dongguan, Guangdong.
A release issued by the Yangtze Optical Fibre and Cable Joint Stock Limited Company said that YOFC, in collaboration with China Mobile and China Telecom, successfully completed this project, along with some others. The three companies also kicked off the world’s first demonstration project of a hollow-core fibre cable transmission system on an existing network, featuring a single-wavelength rate of 1.2 Tbit/s and a one-way transmission rate exceeding 100 Tbit/s.
In May 2024, YOFC, partnering with China Unicom, conducted a hollow-core fibre communication transmission test with a single-wavelength rate of up to 1.2 Tbit/s. This experiment set a new world record for the single-wavelength rate over 10.2km hollow-core fibres and realized a transmission capacity of 32×1.2 Tbit/s.
YOFC and China Telecom have also realized a one-way real-time signal transmission capacity of 100.4 Tbit/s over 20km hollow-core fibres, with a capacity-distance product of 2,008 Tbit/s∙km, marking a record in this regard, added the release.

As per YOFC, it provided a comprehensive suite of technical solutions, such as long-distance, low-loss hollow-core fibres, hollow-core fibre cables, hollow-core fibre splicing services, and adapters for integration with single-mode fibres to these test projects. Working with the three major operators, YOFC has verified the super-large capacity, ultra-low loss, ultra-low latency, and other system transmission performance attributes of hollow-core fibres, as well as the feasibility of deploying these fibres in intricate and demanding network environments.
These world records in optical transmission represent a crucial step forward in advancing hollow-core fibre transmission systems towards greater capacity and longer distances. They mark a significant milestone for the hollow-core fibre and transmission system industry, transitioning from a technology prototype to industrialization. Moreover, they underscored YOFC’s technical strength and leading edge in hollow-core fibres.
Driven by the ongoing advancements in artificial intelligence, fibre communication technology, the “highway” for information transmission, is constantly achieving new milestones. Hollow-core fibre, utilising an innovative air-guiding mechanism, pushes the limits of performance of solid-core fibres in latency, attenuation, and capacity. The technology represents a significant innovation in optical fibre communication technology, and also a ground-breaking solution for next-generation optical communications.
