China Fiber Optic Industry 2025: Supply Chain, Market Share and Global Reach
China's fiber optic industry has grown from a technology importer to the world's largest producer and exporter. With domestic giants such as Yangtze Optical Fibre and Cable (YOFC) commanding over half of global preform output, the sector underpins both China's 5G rollout and international submarine cable projects. Government policies targeting full fiber coverage by 2025 and export incentives have accelerated capacity expansion across multiple provinces.
TL;DR
China manufactures more than 60% of global fiber optic cable and supplies the majority of optical fiber preforms. YOFC alone accounts for roughly one-quarter of worldwide preform capacity. Exports exceeded USD 5 billion in 2024, with Southeast Asia and Europe as the largest destination markets.
Key Insights
Global Market Share
China accounts for over sixty percent of global fiber optic cable production capacity, with YOFC, Futong and Hengtong collectively supplying the majority of submarine and terrestrial cable projects worldwide.
Preform Dominance
Chinese firms produce approximately fifty-five percent of optical fiber preforms, the most value-intensive segment, having invested heavily in VAD and OVD deposition technology since 2015.
Export Value 2024
Fiber optic cable and preform exports reached USD 5.2 billion in 2024, growing twelve percent year-on-year, driven by demand from ASEAN 5G buildouts and European FTTH programs.
Domestic FTTH Penetration
Fixed broadband fiber-to-the-home coverage reached ninety-six percent of urban households by end of 2024, making China the most fiber-connected large economy globally.

Frequently Asked Questions
Yangtze Optical Fibre and Cable (YOFC), headquartered in Wuhan, is the world's largest fiber optic cable manufacturer by revenue and capacity, supplying roughly one-quarter of global optical fiber preform output.
Chinese firms acquired preform technology through joint ventures in the 2000s, then invested billions in vertical integration. YOFC, Futong and Hengtong now operate large-scale VAD and OVD preform furnaces domestically, reducing reliance on imported preforms.
Exports focus on high-capacity cables for 5G and FTTH, targeting ASEAN, Europe and the Middle East. The Belt and Road Initiative has opened submarine cable contracts, and Chinese firms participate in major consortium projects such as PEACE and SEA-ME-WE 6.
By early 2025, China had over 3.7 million 5G base stations, virtually all connected via fiber optic backhaul, requiring enormous volumes of fiber cable and driving continuous domestic demand growth.
