Publisher: DC Market Insights Author: Amit Jain, DC Market Insights Published: 2026-10-15 Last updated: 2026-10-15 Next review: Apr 2027 Page: https://www.dcmarketinsights.com/report/data-center-fiber-optic-cabling-connectivity-market ## Key takeaways - AI halls need more than ten times the fiber - VSFF connectors replace MPO in AI halls - Fiber and preform shortages raise prices - VSFF trunks and cassettes for AI back-end fabrics **Frequently Asked Questions** **How big is the Data Center Fiber Optic Cabling Connectivity Market in 2026?** USD 6.23 billion in 2026, up 17.08% from USD 5.32 billion in 2025, according to DC Market Insights estimates. The market is projected to reach USD 16.69 billion by 2035, a CAGR of 12.12% from 2025 to 2035. **What is the size of the Data Center Fiber Optic Cabling Connectivity Market in 2025 and 2035?** USD 5.32 billion in 2025 and USD 16.69 billion by 2035 (DC Market Insights estimate), after USD 1.76 billion in 2020. The 2025 figure covers fiber cabling for 12,000 MW of new IT capacity plus work on the installed base. **What is the growth rate of the Data Center Fiber Optic Cabling Connectivity Market?** 12.12% a year from 2025 to 2035 (DC Market Insights estimate), slower than the 24.77% of 2020-2025 because fiber dollars per AI MW fall as racks get denser. **What is the Data Center Fiber Optic Cabling Connectivity Market?** USD 5.32 billion of 2025 revenue from passive fiber optic cabling and connectivity inside data centers: fiber cable, pre-terminated assemblies and patch cords, enclosures, cassettes and panels, and fiber pathway. Transceivers and active optical cables are excluded. **Which component leads data center fiber cabling?** Pre-terminated assemblies and patch cords, with 51.81% of 2025 revenue, because AI halls are cabled with factory-tested MPO trunks (DC Market Insights estimate). **What is the fastest-growing segment of data center fiber cabling?** VSFF connectors such as MMC and SN, at 32.40% a year to 2035 (DC Market Insights estimate), because they fit up to three times the fibers of an MPO connector in the same space. **How much does data center fiber cabling cost per MW?** About USD 0.211 million per conventional MW and USD 0.681 million per AI MW in 2025, excluding labor. Both are DC Market Insights estimates. A Panduit 144-fiber OM4 trunk of 30 metres lists at USD 9,022. **Which region leads data center fiber cabling?** North America, with 46.54% of 2025 revenue. The Middle East and Africa is the fastest-growing region at 15.83% a year as Gulf AI campuses are built (DC Market Insights estimate). **Who are the leading companies in data center fiber cabling?** Corning leads with about 26% of 2025 revenue, and Corning, Amphenol and Panduit together hold about 45% (DC Market Insights assessment). Prysmian, Siemon, Legrand, Fujikura and US Conec follow. **Which data center type buys the most fiber cabling?** Hyperscale, with 47.54% of 2025 revenue. GPU and neocloud providers grow fastest at 15.03% a year (DC Market Insights estimate). **How much more fiber does an AI data center need?** More than ten times the fiber of a traditional data center, according to Corning. Content is USD 0.681 million per AI MW in 2025 against USD 0.211 million per conventional MW. Both are DC Market Insights estimates. **How does hyperscale capital expenditure affect data center fiber cabling?** It sets the pace: data center investment reached USD 580 billion in 2025, according to the IEA, and this market is about 0.92% of it. Suppliers are consolidating and adding capacity, as the Amphenol purchase of CommScope CCS and Prysmian's EUR 1.25 billion fiber program show. ## Market by region (USD million) ## Dataset | Series | Value | Unit | | --- | --- | --- | | Market size 2025 | 5,320 | USD million | | Revenue CAGR | 12.12 | % | | Market size 2035 | 16,690 | USD million | ## Frequently asked questions ### How big is the Data Center Fiber Optic Cabling Connectivity Market in 2026?
