Enterprise Network Infrastructure: Design, Performance & Security

Building AI-ready networks: Smart cabling for the edge era

In this exclusive article for DCNN, Rachid Ait Ben Ali, Product & Solutions Manager, Smart Building & Data Center at Aginode, explores how next-generation fibre and automated management systems are redefining infrastructure for AI and edge computing: Cabling for the future As artificial intelligence and edge computing rapidly reshape data centre architectures, network infrastructure has to evolve to keep up. Critical applications such as autonomous systems, real-time analytics, and GPU-to-GPU communication for AI model training are highly sensitive to latency, signal degradation, and disruptions caused by excessive hops or amplification points. To meet fast-moving, rigorous requirements, cutting-edge cabling solutions - including ultra-dense fibre panels and the latest generation of Automated Infrastructure Management (AIM) systems - are essential. A closer look at the requirements AI-driven infrastructure is unforgiving of downtime and demands built-in redundancy. Workloads are often unpredictable and heavily overloaded, which means they need optical cabling that can absorb traffic spikes without performance degradation. Architectures supporting AI are non-linear and bandwidth-intensive, requiring designs with optimised physical pathways. Fibre networks in these settings must be capable of supporting transmission rates of 400G, 800G, and beyond. At the same time, edge computing introduces a new level of complexity. Its highly distributed nature requires fibre connectivity that is not only robust and high-performing, but also low maintenance and compact enough to function within physical and power-constrained environments. As AI workloads - from training to inference - generate immense volumes of east-west traffic across dense GPU clusters, managing connectivity and thermal performance becomes critical. These clusters produce extreme heat, making thermally optimised cabling and carefully considered airflow vital. Addressing challenges from a technical perspective Everything starts with the right cabling. Pre-terminated fibre links support rapid and reliable deployment at hyperscale and edge sites. High CPR-rated solutions help ensure compliance with stringent fire safety standards. As organisations plan for upgrades to 800G or even 1.6 Tbps networks, deploying a future-ready cabling plant is essential. Smart labelling systems simplify identification, reduce downtime, and help teams operate more efficiently. Ultra-polished UPC and APC connectors minimise reflection and insertion loss - crucial for extremely latency-sensitive AI applications. High-density fibre-optic cabling, such as MPO/MTP for parallel optics, enables scalable bandwidth in compact footprints. OM5 multimode fibre is well-suited for dense AI clusters and edge deployments. Supporting multiple wavelengths over short distances and offering tighter loss budgets, OM5 delivers high bandwidth without dramatically increasing cable volume. Modern cable designs enhance performance through quality shielding, precise construction, shorter channel lengths, and cleaner signal paths that reduce hops and signal loss. The network architecture itself also plays a key role. Ethernet backbones operating at 400G and 800G, combined with direct-connect models like leaf-spine or fully meshed fabrics, reduce latency and support AI’s massive east-west traffic patterns. Minimising patching and interconnection points cuts down on signal attenuation and interference, further improving efficiency. Innovations such as ultra-dense fibre panels and MPO connectors help scale operations without overloading valuable rack space and enable rapid deployment while avoiding costly rewiring. AIM systems are becoming indispensable, offering real-time visibility into port status, topology, and usage, and integrating with Data Centre Infrastructure Management (DCIM) and orchestration tools. By leveraging AI-powered tracking and analytics, AIM systems enable real-time monitoring and automate management tasks. This reduces mean time to repair (MTTR), minimises human error, and supports large-scale, AI-driven operations. In environments where model training may take months, cabling with embedded diagnostics ensures uninterrupted operation and transparency. Different types of fibre can be tracked, diagnosed, and reconfigured with minimal manual intervention. That’s essential for mission-critical systems. Further considerations Smooth integration of high-performance fibre into AI and edge-ready environments demands careful attention to detail. As GPU-dense racks fill with fibre, insertion and connection loss must be minimised, which increases the importance of ultra-low-loss multimode solutions. Thermal and spatial constraints in AI deployments necessitate slim, compact cabling designs that do not compromise on performance. Adhering to industry standards such as ISO/IEC OM5 and MPO ensures compatibility across hardware ecosystems and simplifies deployment at geographically distributed edge sites. Looking ahead, future-proofing and sustainability are equally important. Investing in OM5 fibre today helps avoid the cost and disruption of replacement as bandwidth demands continue to grow. Automated cabling systems reduce operational expenditures but also enable agile provisioning, even in edge locations where power is constrained. Low-loss fibre reduces the need for signal amplification, conserving energy, while structured, durable panels minimise long-term maintenance waste. To accommodate the demanding requirements of AI and edge computing, data centre design must transition from legacy copper and basic point-to-point fibre models to high-density, automated multimode fibre ecosystems. Smart cabling, ultra-dense panels, and intelligent management solutions form the backbone of this transformation. These technologies empower both hyperscale and edge operations with high bandwidth, low latency, and operational agility. Meeting the needs of AI-ready infrastructure doesn’t just require speed; it demands ultra-high bandwidth, minimal latency, granular insights, simplified manageability, and flexible (re)configuration. With the right infrastructure, it’s possible to build networks that are powerful enough for AI at scale and flexible enough enough for edge deployment.

Turkish interconnection market projected to double by 2030

According to a new study by DStream Group, commissioned by internet exchange (IX) operator DE-CIX, Istanbul is emerging as a global digital hub and a key interconnection point for data traffic between Europe, the Middle East, and Central Asia. The findings were published to mark the tenth anniversary of DE-CIX Istanbul, Turkey’s largest neutral internet exchange. Over the past decade, the country has moved from a fragmented digital landscape to one of regional integration and growing global importance. Istanbul’s role as a digital hub The study highlights that Turkey has made notable progress in digital infrastructure, with Istanbul at the forefront. A combination of location, an expanding internet exchange market, and rising demand for data services has strengthened the city’s role in regional connectivity. Istanbul’s data centre market is also expanding, supported by demand for cloud services, digital transformation, content delivery, and wider internet penetration. The report forecasts that the city’s interconnection market will exceed 150 networks and carry multi-terabit-per-second traffic by 2030, nearly double today’s levels. Turkey’s position as a land bridge between Europe and Asia offers additional resilience for international connectivity. Nationwide fibre coverage and submarine cable systems landing in the country link directly with more than 20 neighbours, creating alternative routes for data flows. Land-based connections also provide redundancy to European submarine routes, strengthening reliability. Other cities, including Ankara, Izmir, and Van, are also emerging as infrastructure hubs, contributing to a more distributed national network. DE-CIX Istanbul’s role Established in 2015, DE-CIX Istanbul is the country’s first and largest neutral internet exchange, enabling low-latency data exchange between more than 60 networks. The exchange now operates across over ten colocation sites in the city, providing geographic redundancy. According to DE-CIX, 93% of international networks in Istanbul peer through its platform. This has attracted global operators, encouraged development of land-based routes, and most recently supported the launch of an AWS cloud onramp in the city. Bülent Sen, Regional Director of DE-CIX Türkiye, says, “Turkey is no longer just a gateway; it’s becoming a destination for digital investment. We are already seeing massive growth at the exchange. "In early August, the IX surpassed 500 Gbit/s of throughput for the first time, and in September 2025, peak traffic exceeded 533 Gbit/s - up 42% since the start of the year. We expect this trend to continue, driven by the adoption of artificial intelligence, which many businesses now rank as a top investment priority.” Looking to the next decade, DE-CIX predicts that AI and satellite internet will reshape demand for connectivity. Ivo Ivanov, CEO of DE-CIX, adds, “With a commitment to neutrality, DE-CIX Istanbul is poised to anchor regional data flows and support the digital future of the whole region. "AI and satellite-based internet will significantly reshape the connectivity landscape in the coming decade. Turkey is well-placed to play a major role in this transformation.” The study suggests Turkey should focus on attracting hyperscale cloud providers, increasing CDN deployments, and broadening its interconnection ecosystem. It also recommends regulatory reform, greater infrastructure liberalisation, and stronger public-private partnerships to support the country’s digital economy. For more from DE-CIX, click here.

Future-proofing network infrastructure

In this exclusive article for DCNN, Warren Aw, Chief Commercial Officer at Epsilon Telecommunications, highlights why agile, high-capacity connectivity is the critical ingredient for resilience in an era of relentless digital demand: Colocation, connectivity, and continuity In today’s digital landscape, business IT environments are becoming increasingly sophisticated and, with that, more complex. Whether it’s an enterprise working to stay ahead of increasingly digitally savvy consumers, or a service provider keeping those enterprise services and workloads up and running, network downtime is no longer an option. Downtime is more than just an inconvenience; it’s a major threat to revenue and reputation. For 90% of mid-to-large-sized enterprises, just one hour offline can cost more than $300,000 (ITIC) (£221,000). Despite this, many businesses are still relying on infrastructure that wasn’t built for the scale, speed, or strain of today’s digital demands. Whether the services are mission-critical or not, a bad online experience can make or break customer relationships in an instant. Customers now expect always-on availability for a wide range of services, such as streaming video content, collaborating in the workplace, performing financial transactions, or accessing cloud services. Business continuity was once a contingency plan, but it has now become a competitive advantage. That being said, ensuring continuity is also becoming more difficult due to growing data volumes, AI workloads, rising user expectations, and a more distributed business application ecosystem. This, coupled with real-world constraints like power limitations, infrastructure strain, and inconsistent SLAs, is making it more important than ever for businesses to re-evaluate their network and business continuity strategies to stay resilient, particularly if legacy infrastructure is still in play. Colocation, when combined with agile, high-capacity connectivity, can provide a simpler, smarter way for businesses to keep service access and delivery both online and ahead in a competitive market. Colocation really is more than just racks and servers; it’s an opportunity to future-proof network infrastructure with adaptability, scalability, and reliability at the core. Legacy infrastructure limitations As businesses deploy more data-intensive applications, compact edge computing devices, and AI workloads, rising demands are putting increased strain on legacy infrastructure and on-premises environments. This includes: • Power constraints – Modern applications require newer, high-density equipment, which significantly increases power requirements.• Downtime risks – Legacy infrastructure and single points of failure raise the likelihood of outages, damaging SLAs, revenue, and brand reputation.• Business continuity gaps – Without resilient infrastructure and built-in redundancy, organisations face growing challenges in maintaining always-on availability.• Scalability challenges – On-premises infrastructure can be slow and expensive to scale in response to customer demands or new market opportunities.• High costs – Cooling, power, staffing, and maintenance are stretching budgets and internal team resources.• Inter-provider complexity – Managing connectivity across multiple clouds, partners, and carriers is complex, time-consuming, and prone to performance issues without the right interconnect fabric. These limitations are pushing IT leaders to look for modern, flexible infrastructure strategies that can grow with their business. Colocation for business continuity Colocation is more than just renting space in a data centre; it’s a strategic way to strengthen business continuity while simplifying IT infrastructure. Instead of maintaining costly on-premises facilities, organisations can host critical infrastructure in purpose-built, third-party data centres. This shift not only reduces capital expenditure, but also enables teams to focus on innovation rather than infrastructure. Colocation provides robust power, security, and carrier-neutral connectivity to a global network ecosystem designed to prioritise uptime, resilience, and reach. One of the key advantages of colocation is dual-site access, which allows businesses to distribute their infrastructure across two geographically separate, interconnected facilities. This setup is vital for disaster recovery and redundancy planning. If one site experiences a disruption – whether due to a power failure, natural disaster, or hardware issue – traffic and workloads can seamlessly fail over to the second site, minimising downtime and ensuring uninterrupted service delivery. Colocation also supports business continuity by offering high-speed, low-latency connectivity to clouds, carriers, and partners. On top of this, it offers physical security and environmental controls that exceed most in-house capabilities, as well as power and cooling infrastructure designed for high-density, mission-critical workloads. Beyond continuity, it brings cost-efficiency, operational simplicity, and access to a broader ecosystem of services. Colocation enables enterprises and service providers to focus on delivering value, rather than managing infrastructure. Mitigating risk, maximising uptime With increasingly complex IT environments and 24/7 availability becoming the new norm, having the right infrastructure in place is crucial. Colocation offers a practical, scalable way to support business continuity, reduce risk, and stay flexible in a changing landscape. Epsilon offers colocation services across key hubs in London, Singapore, New York, and South Korea. Each facility provides 99.999% uptime and robust power backup, as well as direct access to our global network fabric of over 500 data centres, clouds, and internet exchanges via our NaaS platform, Infiny. By future-proofing network infrastructure, colocation can maximise uptime, improve customer experiences, and build new competitive advantages that can support long-term business goals. Ultimately, colocation provides the stable foundation that organisations need to safeguard operations in an unpredictable world. Business continuity is no longer a backup plan; it’s a competitive differentiator. For more from Epsilon, click here.
