Data Center Fiber Optic Cabling and Connectivity Market

Dublin, Nov. 05, 2026 (GLOBE NEWSWIRE) -- "Data Center Fiber Optic Cabling and Connectivity Market Size, Share, and Industry Analysis - Global Forecast to 2036" has been added to ResearchAndMarkets.com's offering.

The global market for data center fiber optic cabling and connectivity was valued at USD 12.97 billion in 2025 and is estimated to reach USD 16.41 billion in 2026. Revenue is projected to rise to USD 35.93 billion by 2036, representing a CAGR of 8.1% during the forecast period. The report evaluates market size, data center capacity, investment patterns, fiber intensity, production capacity, pricing, technology development, standards, supply chains, competitive activity, and long-term growth opportunities.

Demand is accelerating as artificial intelligence infrastructure, cloud expansion, and higher network speeds increase fiber requirements. The four largest hyperscalers have guided combined 2026 capital expenditure of approximately USD 725 billion, while global data center capacity under construction more than doubled to 31.7 GW in 2025. Reflecting this momentum, Corning reported a 32% increase in Optical Communications sales in the second quarter of 2026.

Supply remains a major market constraint. Preform and fiber production capacity has not kept pace with demand, contributing to higher prices and longer lead times since mid-2025. New preform facilities can take up to two years to complete, while shortages of skilled installers add cost and execution risk. These conditions are encouraging data center operators to adopt pre-terminated systems and secure supply through multi-year agreements, customer prepayments, and localized manufacturing.

Market Drivers and Technology Trends

AI data center construction is the leading growth driver because AI clusters use substantially more fiber per megawatt than conventional facilities. Record hyperscale investment is sustaining the construction pipeline, while migration to 800G and 1.6T networks is increasing fiber counts through parallel optics and breakout configurations. Multi-building campuses are also expanding demand for high-fiber-count backbone and interconnect cables.

Several technologies are expected to outperform the wider market. Pre-terminated assemblies are gaining adoption because they reduce field termination requirements and accelerate deployment. Very-small-form-factor connectors and ultra-high-density panels support the connection density required in AI racks. Hollow-core fiber, which can reduce latency by approximately 30%, is progressing from trials to commercial data center interconnect deployments. Optical scale-up and co-packaged optics may create additional in-rack fiber demand later in the decade.

Market risks include constrained power and grid access, project delays in major data center hubs, dependence on a limited number of hyperscale buyers, tariffs, and changing sourcing requirements. However, edge infrastructure, regional data centers, sovereign cloud investment, and production localization are creating opportunities beyond established markets.

Segment Analysis

Product type: Optical fiber cables are expected to hold the largest share in 2026 due to demand for high-fiber-count backbone, campus, and interconnect infrastructure. Pre-terminated assemblies are projected to grow the fastest as MPO/MTP trunks and harnesses replace field termination.

Fiber type: Single-mode fiber is expected to lead the market because of its extensive use in backbone, leaf-spine, AI fabric, and campus links at 400G and above. Hollow-core fiber is forecast to record the fastest growth from a smaller base.

Connector type: MPO/MTP is expected to retain the largest share as a standard interface for parallel optics and pre-terminated trunks. Very-small-form-factor connectors, including SN, MDC, SN-MT, and MMC, are forecast to expand rapidly.

Network segment: Switch-to-switch connections are expected to represent the largest segment, supported by leaf-spine and AI fabric architectures. Data center interconnect is projected to grow the fastest as operators develop multi-building AI campuses and distributed training environments.

Data center type: Hyperscale & cloud facilities are expected to hold the largest share and achieve the fastest growth, driven by capital expenditure and the high fiber intensity of AI infrastructure.

Application: AI & HPC clusters are projected to lead in both market share and growth as high-speed optical networks connect increasing numbers of accelerators.

Regional Market Opportunities

The report analyzes North America, Europe, Asia-Pacific, the Middle East & Africa, and Latin America across 29 countries and sub-regions. The assessment considers installed and planned capacity, AI investment, power availability, data sovereignty, manufacturing footprints, and trade policy.

North America is expected to account for the largest global share in 2026, led by the U.S. The region contains many of the world's largest data center markets and AI campuses and is attracting new manufacturing investment from Corning, Prysmian, and Fujikura.

The Middle East & Africa is forecast to grow the fastest, supported by gigawatt-scale AI campuses and sovereign cloud projects in the UAE and Saudi Arabia. Asia-Pacific holds the second-largest share, with China as its largest market and India expected to grow the fastest, followed by Malaysia. Germany leads Europe, while the Nordics are positioned for strong growth due to renewable power availability. Brazil is Latin America's largest market, and Mexico is expected to achieve the region's fastest expansion.
