YOFC and China Mobile Debut World's First 800G Hollow-Core Fibre Transmission Network

Key performance metrics achieved on a 20km test link—such as splice losses between hollow-core fibres, connections from hollow-core to solid-core fibres, and attenuation post-installation—were benchmarked against leading global standards. Moreover, the deployment featured an 800Gbps single-wavelength optical transmission setup, achieving a bidirectional long-distance transmission test with a throughput of 128Tb/s over hollow-core fibres. This not only demonstrated the practical application of such fibres in intricate and demanding network environments but also served as a critical proof-of-concept for the scalability and industrial applicability of hollow-core fibre technologies.

New technological heights are being achieved across the sector, driven by the ongoing advancements in artificial intelligence. Hollow-core fibre, utilizing an innovative air-guiding mechanism, surpasses the performance constraints associated with traditional solid-core fibres in both capacity and latency. The technology offers marked improvements in data transport infrastructures such as internet backbones and data centers, and is expected to continue meeting the growing demands for data transmission for the next 20 years and beyond.

YOFC plans to advance the development and manufacturing of next-generation hollow-core fibre technologies. Working with industry allies, YOFC seeks to foster innovation, fast-track the commercialization of new fibres, and boost optical network performance, establishing a solid foundation for the fibre infrastructure essential for a smarter world.
