Hollow‑core fiber has advanced from pilot validation to mass‑scale commercial deployment

YOFC has secured 100% share of China Telecom Guangdong 2026 framework tender for hollow‑core and G.654‑E optical cables, with a tax‑inclusive bid price of CNY 159 million.

This is China’s largest‑ever single hollow‑core fiber procurement, marking large‑scale commercial adoption of hollow‑core technology.

As a pioneer in industrial‑grade hollow‑core fiber, YOFC masters self‑developed key raw‑material mass‑production. Shipment has surpassed 10,000 core‑km. We hold multiple world records including 0.04 dB/km minimal attenuation, 91.2 km one‑time fiber drawing and a 100‑km operational cable route.

More than 13 domestic‑and‑overseas commercial‑trial deployments have been completed. Our 110‑km cross‑border hollow‑core link between Dongguan and Hong‑Kong stock‑exchange data centres hits record‑low round‑trip latency of 0.93 ms. A world‑first 1.2 Tb/s single‑span unrepeated transmission test was also accomplished with China Telecom.

Moving forward, YOFC will keep innovating hollow‑core fiber hardware to satisfy AI‑era extreme bandwidth and latency requirements and upgrade global digital‑communication infrastructure.
