Simplify your network expansion with managed network services

Managed Optical Fiber Network (MOFN) is the new industry term for the well-established Managed Network service which Arelion has provided since 2012. We have built fully dedicated customer networks and dedicated transponder shelves on shared systems, providing multi-terabit scale.

With a surge in AI-driven traffic, upgrading networks swiftly and efficiently has become a real challenge. For most organizations, building networks is not their core business; what they actually need is fast and reliable access to network capacity. 

At Arelion, our long-standing expertise in both constructing and managing high-capacity networks makes us the ideal partner for scaling your future network infrastructure.

MOFN for enterprises

A Managed Optical Fiber Network (MOFN) is a strategic solution for today’s enterprises, especially as data center locations and network demands continue to evolve. Let’s explore a few of the most common customer scenarios.

Connecting dedicated data centers

Data centers are now often located where electricity is available rather than where network connectivity is optimal. MOFN bridges this gap by providing dedicated, high-performance fiber connections that link these remote DCs to public and private cloud environments. For customers, this simply ensures seamless access to their cloud environment and services.

Enhanced security through physical separation

Security remains a top priority for enterprises handling sensitive data. MOFN provides physically separated infrastructure - dedicated fiber lines, meeting the highest security standards. This physical isolation reduces drastically the risk of data breaches and supports compliance with strict regulatory requirements.

Futureproofing amid end-of-support challenges

With aging equipment reaching end-of-support, enterprises are now at a crossroads. MOFN presents an opportunity to transition to a more efficient, managed model—reducing operational complexity while maintaining control and performance.

    Managed Optical Fiber Network use cases

    Metro connectivity

    MOFN provides high-capacity fiber links within metropolitan areas, enabling fast and reliable connectivity for operators and enterprises. E.g.:

    • Telecom operators sharing fiber routes in Stockholm for mobile backhaul
    • Banks or hospitals connecting multiple branches to a central data center within the city
    • Businesses using MOFN to link offices to local cloud regions for low-latency services
    Long distance over shared network

    MOFN allows multiple operators to share fiber infrastructure for regional or national connectivity, reducing costs while maintaining performance. E.g.:

    • ISPs in Sweden using a common fiber backbone to connect Gothenburg, Malmö, and Stockholm
    • Smaller operators leasing capacity from a managed fiber network provider instead of building their own long-haul routes
    • Nordic operators sharing fiber routes for connectivity between Sweden, Norway, and Finland
    Dedicated network

    MOFN offers exclusive fiber paths for critical applications, ensuring security, guaranteed bandwidth, and SLA compliance. E.g.:

    • A stock exchange requiring a private fiber link for ultra-low latency trading
    • Secure fiber connectivity for defense or public safety agencies
    • Hospitals using dedicated fiber for transmitting sensitive patient data between facilities
    AI use cases

    MOFN supports AI workloads with ultra-high bandwidth and low-latency connectivity for data-intensive operations. E.g.:

    • Linking hyperscale data centers for AI model training and inference.
    • Universities or research labs connecting GPU clusters across campuses.
    • Autonomous vehicle companies transmitting real-time sensor data to central AI systems for processing.
