As of the close of April 20, four optical communication listed companies from Hubei—Yangtze Optical Fibre, Huagong Tech, FiberHome, and Accelink—had a total market value exceeding 500 billion yuan, reaching 518.5 billion yuan.
Among them, Yangtze Optical Fibre’s A-shares surged 5.22% to 385 yuan per share, while its H-shares rose to 211.6 Hong Kong dollars, giving it a total market value of 234 billion yuan (converted to renminbi). Huagong Tech’s stock price was 114.98 yuan, with a market value of 115.7 billion yuan. Accelink’s market value reached 96.9 billion yuan, just shy of 100 billion. FiberHome’s market value stood at 71.9 billion yuan.
In addition to these four optical communication companies with global influence, Hubei also holds a national strategic asset—Yangtze Memory Technologies. Once it goes public, it is expected to become the largest IPO in China’s technology sector in recent years.
In 2025, the Hurun Global Unicorn Index listed Yangtze Memory for the first time, valuing it at 160 billion yuan. It ranked among China’s top ten unicorns and 21st globally, becoming the highest-valued new unicorn in the semiconductor industry at that time.
The integrated rise of Hubei’s optical communication and integrated circuit sectors is closely tied to the AI wave.
In the AI era, computing centers require optical fiber for signal transmission, optical modules to convert between electrical and optical signals, and storage chips to store data. Computing power is as critical as oil.
Riding the wave of massive global computing center construction, the optical fiber, optical modules, and storage chips from Optics Valley are selling rapidly.
Yangtze Optical Fibre and FiberHome focus on optical fiber. On March 27, Yangtze Optical Fibre released its annual report, showing revenue of 14.252 billion yuan in 2025, a year-on-year increase of 16.85%, and net profit attributable to shareholders of 814 million yuan, up 20.4%.
Huagong Tech and Accelink specialize in optical modules. On April 14, Huagong Tech’s first-quarter 2026 performance forecast indicated that driven by surging demand for AI computing power, orders for optical modules grew rapidly, with shipments of high-speed modules such as 400G, 800G, and 1.6T significantly increasing. Profit is expected to rise by about 120% year-on-year. Net profit attributable to shareholders in the first quarter is projected to grow by 46.38% to 56.13%.
Due to booming demand for NAND flash memory from AI servers, smartphones, and data centers, storage chips are in short supply. This “super cycle” for storage chips, ignited by AI, will continue to benefit Yangtze Memory.
In fact, before Hubei’s optical communication giants collectively crossed the 500 billion yuan threshold, they had been relentlessly pushing boundaries for decades—working on optical fibers thinner than a human hair, pursuing the world’s fastest optical transmission speeds, developing world-class ultra-high-speed optical modules, and perfecting storage chips the size of a fingernail.
Now, China Information and Communication Technologies Group (which includes FiberHome and Accelink) continues to break its own world records in optical transmission speed, with the ability to download 14,000 4K movies in one second. Yangtze Optical Fibre has led global sales of optical fiber preforms, optical fiber, and optical cables for ten consecutive years. More than 70 “firsts,” including the world’s first 12.8T XPO optical module, have emerged from Huagong Tech.
Today, Optics Valley, Hubei’s hub for the optical communication industry, is the world’s largest research and manufacturing base for optical fiber and cables, China’s largest production base for optoelectronic devices and research base for optical communication technology, as well as a key cluster for the integrated circuit industry and a laser industry base.
