Data Center Interconnect Market Share, By Deployment Mode, 2024

Based on deployment mode, the data center interconnect market is segmented into On-Premises, Cloud, and Hybrid. The on-premises segment dominates the market accounting for around 55.9% share in 2025, and the segment is expected to grow at a CAGR of over 13.1% from 2026-2034.
 

  • On-premise DCI solutions can enable organizations and in particular hyperscalers and large enterprises to control their network infrastructure. It is important in safe, quick, and low-latency transmission of information regarding mission-critical data centers. It allows fancy customization too, thus is suitable to high-performance workloads like training of AI models, HPC, and financial trading systems. 
     
  • On-premise DCI is essential in several industries including government, healthcare, and BFSI where some strict local data residency laws must be adhered to and meet stringent data security regulation. On-premise systems assist in keeping sensitive information inside the domain of an organization, and they adhere to the GDPR, HIPAA, and regional data security regulations without the help of third-party cloud connections.
     
  • For example, in November 2023, Nokia launched the Cloud DCI solution, which is specifically focused on the on-premises enterprise connectivity within the private and hybrid data centers. The 1830 Photonic Service Switch platform allows customers to create high-speed and secure optical networking connections inside their own buildings to support synchronous and asynchronous data replications and disaster recovery over metro and long-haul connections.
     
  • Organizations having a large investment in tangible network infrastructure tend to want to use on-premise deployment to utilize pre-installed routers, switches, and fiber. Such a strategy includes long-term ROI and seamless integration with the existing IT systems and a private cloud.
     
  • The hybrid segment is projected to grow at a CAGR of over 15% owing to the rising adoption of multi-cloud initiatives by enterprises. Different organizations desire the extendibility to handle their important workloads on-site and can use cloud scalability on treatable operations. Hybrid DCI supports effortless interconnectivity, data mobility, and enforcement and can thus be used to optimize the performance, compliance and costs of deployments of modern digital infrastructure. 
     

Based on technology, the data center interconnect market is segmented into synchronous optical network (SONET), dense wavelength division multiplexing (DWDM), ethernet, optical transport network (OTN), and others. The dense wavelength division multiplexing (DWDM) segment is expected to dominate the market with around 57.9% share due to its ability to deliver ultra-high bandwidth and long-distance data transmission essential for hyperscale data center interconnects.
 

  • Dense wavelength division multiplexing (DWDM) is the most decorated technology with maximum market share in the data center interconnect (DCI) market as it is the only technology with the capability to maximize the fiber capacity. DWDM is a method that allows sending a variety of information signals simultaneously using a single optical fiber by giving each signal a different wavelength. This enables data centers to scale bandwidth costs effectively, and this is crucial owing to the exponentially increasing inter-data-center traffic due to AI, cloud computing, and big data analytics.
     
  • In addition, DWDM is preferred in long-haul and metro DCI deployments where low latency, high reliability and the highest throughput is required. Its high order modulation formats and its coherent transmission enable data rates up to 100G, 400G, 800G to be transmitted over long distances without signal degradation which reduces the need to regenerate signals and reduces the cost of operations.
     
  • For instance, in June 2025, Nokia, partnering with CSC and SURF, achieved record 1.2 Tbps DWDM transmission over a single wavelength on a long-haul EU network, designed to serve the upcoming LUMI-AI supercomputer. This deployment underscores DWDM’s ability to deliver ultra-high capacity over extended distances, catering to AI-intensive computational workloads.
     
  • DWDM infrastructure is becoming a significant investment of leading telecom and cloud operators that pursue the invisible connection across geographically fragmented facilities. Other companies, such as Ciena, Nokia, and Huawei are also working on DWDM systems that have integrated automation and SDN capabilities, which continue to add to the attractiveness of these systems in dynamic, scalable and forward-looking DCI networks.
     
  • The optical transport network (OTN) segment is projected to experience high growth because it assures good error correction, efficiency in management of bandwidth, and multi-service transport bands over long distances. OTN can be used to interconnect data centers securely and reliably and provide high-speed, low-latency data transport that is critical to AI-driven applications and workloads, cloud applications and real-time data replication within distributed systems environments.
     

Based on end use, the data center interconnect market is divided into communications service providers (CSPS), internet content providers & carrier-neutral providers (ICPS/CNPS), government, and enterprise. The enterprises dominated the market.
