The bidding outcome of the 2026 Framework Procurement Project for Hollow‑Core Optical Cable and G.654‑E Optical Cable launched by China Telecom Guangdong Branch has been officially announced recently.YOFC (Yangtze Optical Fibre and Cable Joint Stock Limited Company) has been awarded the full tender quota with a tax‑inclusive quotation of CNY 159 million.

This tender ranks as the biggest standalone hollow‑core fiber purchase across the domestic telecom market. Its successful award signals that hollow‑core fiber technology has advanced from field verification and pilot testing into large‑scale commercial‑use phase, and fully validates YOFC’s leading‑edge competence inside the hollow‑core fiber sector.

As the global front‑runner for hollow‑core‑fiber industrialisation, YOFC achieves independent research‑and‑development and mass‑manufacturing capacity covering all essential raw‑material components.The company’s accumulated hollow‑core‑fiber delivery volume has exceeded 10,000 core‑kilometres. Multiple world benchmarks have been created: the minimum attenuation of 0.04 dB/km, the maximum one‑time drawing length of 91.2 km and the longest 100‑kilometre commercial‑service fiber route.

Benefiting from deep‑rooted technical reserves and dependable bulk‑order delivery capability, YOFC’s hollow‑core fibers have been deployed in over 13 commercial and pilot‑run projects worldwide, establishing our status as the supplier with the broadest global commercial layout of hollow‑core products.

This landmark bid victory marks another milestone within the long‑term strategic partnership between YOFC and China Telecom.Both parties previously constructed the world’s longest operational hollow‑core‑fiber cross‑border cable. Stretching 110 km, the cable links the data centres of Dongguan and Hong‑Kong stock exchanges and achieves an industry‑leading bidirectional latency down to 0.93 ms.Besides, the world’s first on‑site field trial of single‑wavelength 1.2 Tb/s ultra‑long‑span unrepeated WDM transmission on hollow‑core fiber was completed, setting a brand‑new world record for capacity‑distance product.

Starting from joint technical innovation to large‑volume carrier procurement, YOFC and China Telecom keep pushing technical boundaries. Hollow‑core fiber has been transferred from laboratory prototypes to live telecommunication networks, and transformed from scattered pilot sites to regional‑wide mass deployment.

Technical breakthroughs and commercial expansion progress hand‑in‑hand. With sustained innovation and mature industrialisation capability, YOFC accelerates hollow‑core‑fiber large‑scale commercialisation.Against the extreme bandwidth and low‑latency requirements brought by artificial‑intelligence computing, YOFC will continue research on core hollow‑core‑fiber technologies. Together with industrial‑chain allies, we will build next‑generation optical‑network infrastructure characterised by huge bandwidth, ultra‑low latency and outstanding reliability, and continuously empower the upgrade of worldwide digital infrastructure.
