WUHAN, China, June 15, 2024 /PRNewswire/ -- On June
6, Yangtze Optical Fibre and Cable Joint Stock Limited Company
(YOFC), in collaboration with China Mobile, unveiled the world's
first 800G hollow-core fibre transmission test network in
Shenzhen-Dongguan, Guangdong. The development is a significant
milestone in the evolution of telecommunications infrastructure,
pushing the boundaries of traditional fibre optic technology.
YOFC's participation in the test network featured a
comprehensive suite of solutions specifically designed for
hollow-core fibre optics, encompassing the provision of cables,
essential splicing services, and adapters for integration with
single-mode fibres. The project successfully navigated several
technical challenges common in complex installations. The
challenges involved mitigating environmental risks and ensuring
robust infrastructure during fibre laying and splicing
operations—addressing pipe flooding, managing excessive humidity,
and conducting precise splicing in outdoor environments. These
efforts were crucial in enabling a detailed evaluation of the
fibre's performance under real operational conditions.
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.
