How to interpret the recent price trend of optical cables
In the latest Optical Fibre and Cable Market Outlook, CRU examines the recent acceleration in fibre pricing and the tightening supply conditions emerging in early 2026. Since early 2026, the fiber optic cable price has been rising at an extraordinary pace. In some cases, suppliers only guarantee quotations for the same day, and in extreme situations even half-day quotations are appearing in the market. After an extended period of subdued pricing in several regions, optical fibre prices are rising sharply alongside sustained demand. The global fiber optic cable market was valued at USD 13 billion in 2024 and is estimated to grow at a CAGR of 10. 21% during the forecast period from 2026 to 2035.
