Europe Data Center Interconnect Market Size, Share - Growth Analysis Report and Forecast Trends 2026-2030

The Europe DCI market encompasses the technologies and services used to link data centers across the region, including optical networking equipment, DCI software platforms, and managed services. Valued at roughly $2.11 billion in 2025, the market is on a strong upward trajectory, with projections ranging from $3.86 billion by 2030 to over $5 billion by 2033 depending on the forecast model. Growth rates consistently hover in the 12.5% to 13.4% CAGR range, positioning it among the faster-growing segments of the broader European data center ecosystem, which itself is valued at nearly $59 billion in 2025.

• •Europe DCI market valued at approximately USD 2.11-2.14 billion in 2025 with projected growth to USD 3.86-5.49 billion by 2030-2033
• •Market growing at a CAGR between 12.5% and 13.4%, supported by cloud expansion and hyperscale data center buildouts
• •Part of a broader European data center market forecast to reach over USD 126 billion by 2034, growing at an 8.86% CAGR

Cloud migration remains the single largest catalyst, as enterprises across Europe increasingly adopt multi-cloud and hybrid-cloud strategies requiring seamless interconnection between on-premises, colocation, and public cloud environments. The rollout of 5G networks and the proliferation of edge computing deployments are pushing compute and storage closer to end users, which in turn drives demand for high-capacity, low-latency DCI links. Regulatory factors such as GDPR and growing emphasis on EU data sovereignty encourage enterprises to maintain data within European borders, increasing the need for robust intra-European interconnect infrastructure.

• •Cloud service demand and hybrid multi-cloud architectures are primary growth catalysts, requiring seamless data movement between distributed environments
• •5G edge deployment and AI compute workloads are accelerating demand for high-bandwidth, low-latency interconnects
• •EU data protection regulations (GDPR) and data sovereignty requirements push organizations toward domestic data center infrastructure, fueling DCI investment

The European DCI market is typically segmented by solution type (hardware, software, and services) and by application (hyperscale data centers, colocation facilities, telecom, and enterprise networks). Hardware components, including optical transceivers, switches, and routers, constitute the largest share, though software-defined networking and managed services segments are gaining traction. Germany is a leading market within Europe due to its strong industrial base, central geographic location, and significant hyperscale and colocation data center presence, while the UK, France, and the Netherlands also represent major demand centers.

• •Market segmented across hardware (optical transceivers, switches, routers), software, and managed services, with hardware holding the dominant share
• •Germany leads the European DCI market, supported by its hyperscale data center ecosystem and strategic geographic position
• •The UK, France, and Netherlands are key secondary markets, driven by major cloud provider infrastructure and financial services demand

What are the recent trends and outlook?

A defining technology trend in the European DCI market is the ongoing transition from 100G to 400G and 800G optical transceivers, driven by the exponential growth in data traffic from AI workloads, video streaming, and cloud services. Software-defined networking (SDN) and network automation are gaining adoption, enabling more flexible, scalable, and cost-effective DCI management across complex multi-vendor environments. Looking ahead, the convergence of AI infrastructure demands, continued 5G edge expansion, and persistent data sovereignty pressures will sustain strong market growth through the end of the decade, with Europe positioned as a key global DCI investment region.

• •Transition to 400G and 800G optical transceivers is accelerating to meet bandwidth demands from AI workloads and hyperscale cloud traffic
• •Software-defined networking (SDN) and network automation are increasingly adopted to simplify DCI management across heterogeneous infrastructures
• •AI data center buildouts, continued edge computing expansion, and EU regulatory requirements will sustain double-digit market growth through 2030
