Our country's optical fiber exports increased by 63.6% year-on-year. The F5G concept opened high, with Mingpu Optical Magnet and Reecounda hitting the daily limit.

April 1, the F5G concept opened higher and rose. As of the time of this report, constituent stocks Mingpu Guangci (002902.SZ) and Ruizhi Kangda (603803.SH) hit the daily limit, while China Bei Communications (603220.SH), Feiling Kexi (301191.SZ), Chunqiu Electronics (603890.SH), Deko Li (688205.SH), Yiwa Co., Ltd. (002897.SZ) and others also moved up.

At the same time, the fiber-optic concept sector also climbed. Optical and Electronic Shares (600184.SH) notched two straight daily limits over 2 trading days, while Jept (688025.SH), Tianfu Communication (300394.SZ), Juguang Technology (688167.SH), Lingyun Optics (688400.SH), and others followed higher.

It’s reported that, as F5G—i.e., the fifth-generation fixed fiber network—delivers gigabit-level ultra-high-speed, low-latency connections, it is a core driver for upgrading terrestrial networks. It is currently benefiting from the dual-gigabit policy, and the market is accelerating its expansion.

On the news front, a research report from CITIC Jianxiong Securities said that in February this year, China exported 3,779.9 tons of fiber optic cables worth 790 million yuan, up 63.6% and 126.8% year over year, respectively. If converted into kilometer figures, in February China exported about 25.2 million fiber-kilometers, accounting for roughly 65% of China’s monthly effective production of fiber optics.

In addition, according to CCTV Finance, China-made optical cable orders are booming globally. A staff member of a certain company told reporters that since the end of last year, the company’s overseas order volume has increased significantly. Orders are coming from South America, the Middle East, and Africa, as well as numerous orders from Southeast Asia, and the delivery cycle requirements are all no more than half a month. In the first two months, this company’s fiber-optic export volume grew 51% year over year. Production capacity is now fully scheduled. During this period, the company is stepping up expansion of factory space, adding production lines, and increasing capacity to meet market demand.

Industry insiders believe that the sharp rally in the fiber-optic sector is mainly driven by rising fiber-optic prices and a surge in AI compute-power demand.

Due to the rapid development of AI and compute-power networks and the difficulty of scaling up production, fiber-optic prices have continued to rise. A research report from China Galaxy Securities said that on the demand side, intelligent computing centers have seen a major increase in demand for DCI (data center interconnect) and all-optical networks. According to CWW and CRU data, in 2025 global demand for optical fiber and optical cable is expected to grow 4.1% year over year, while total demand for optical fiber and optical cable from data centers is expected to grow 75.9% year over year. In the future, it will drive global fiber demand to rise to 880 million fiber-kilometers by 2027. On the supply side, because the global production expansion cycle for optical preforms is relatively long (the expansion cycle for optical preforms to optical fiber is about 2 years), but amid the earlier backdrop of price pressure, overall expansion has been relatively conservative, and the market currently tilts toward specialty optical fibers. Combining both demand and supply, the institution believes that fiber-optic cable prices still have room to rise.
