Optical DCI Architectures: Connecting Data Centers at Scale
To effectively connect data centers, enterprises can leverage different optical DCI architectures based on their operational needs:
Wavelength Division Multiplexing (WDM) and Optical Transponders
The most traditional approach to optical DCI involves using a WDM line system and optical transponders. This setup best suits high-capacity, long-reach applications, including intercontinental submarine links. Nokia offers advanced Photonic Service Engines (PSEs) optimized for capacity, reach, and fiber efficiency.
- WDM: Multiplexing many optical wavelengths on one fiber to multiply capacity.
Digital Coherent Optics (DCO) for Metro-Regional Connectivity
For data centers operating within a metro-regional range, an emerging solution is using pluggable Digital Coherent Optics (DCOs) directly within network routers. DCOs eliminate the need for external transponders, reducing hardware complexity and cost while maintaining high-speed, secure connectivity.
- DCO (Digital Coherent Optics): Pluggable coherent optics in routers for metro/regional 100–400G wavelengths without external transponders.
Dark Fiber for Private DCI Builds
Enterprises with stringent data sovereignty and control requirements can deploy private DCI solutions using dark fiber. This approach enables organizations to maintain full control over their network infrastructure while benefiting from high scalability and low operational costs.
- Dark Fiber: Leased/owned unlit fiber you light with your own optics for full control.

Building vs. Buying a DCI Solution: Making the Right Choice
Enterprises evaluating their DCI strategy must consider whether to build a private DCI network using dark fiber or opt for a managed service. This decision hinges on several factors, including security, performance, cost, and operational control.
Control and Security
Security control is paramount for organizations that handle sensitive or regulated data. A private DCI build allows enterprises to implement encryption, authentication, and monitoring protocols, reducing reliance on third-party service providers. This is particularly important for finance, healthcare, and government industries, where data privacy and compliance requirements are strict.
Scalability and Performance
Managed DCI services provide convenience but often come with predefined service levels and limited scalability. In contrast, a private DCI build enables businesses to expand network capacity on demand, ensuring bandwidth and latency meet their evolving needs. Dark fiber-based DCI enables enterprises to fully leverage high-speed, low-latency connections without being constrained by a service provider’s infrastructure limitations.
Operational Costs
While a private DCI build requires a higher initial capital expenditure (CAPEX) for fiber procurement and equipment installation, it can lead to significant long-term operational savings (OPEX). Managed services typically entail recurring costs that increase over time, whereas private infrastructure enables businesses to amortize their investment and reduce their reliance on external providers. Additionally, as data demands grow, private DCI offers cost-effective scalability with lower incremental costs than managed alternatives.
Network Reliability and Uptime
A private DCI build provides organizations with direct network oversight, allowing them to implement redundancy and failover strategies tailored to their specific requirements. While often reliable, managed services may not offer the same level of customization in redundancy planning. For enterprises with mission-critical applications, ensuring maximum uptime and minimizing disruptions is a key consideration in favor of a private build.
Customization and Flexibility
Building a private DCI network gives enterprises complete control over their infrastructure. They can tailor routing, traffic prioritization, and security policies to fit their unique business needs. Managed services, by contrast, often come with standardized configurations that may not align with an organization’s specific operational requirements.
Long-Term Strategic Value
For businesses with long-term IT strategies, a private DCI network can be a strategic investment that provides sustained value. Owning the infrastructure ensures independence from vendor pricing fluctuations, service restrictions, and potential network congestion from shared services. It also enables enterprises to future-proof their IT environments by incorporating emerging technologies like quantum-safe encryption and SDN-driven automation without waiting for service providers to roll out updates.
