IT Infrastructure

Compliance with British and European standards is fundamental to delivering telecoms infrastructure and data centre environments successfully. Standards such as the BS EN 50600 series, alongside the associated telecoms, cabling, power, earthing, fire protection, and resilience standards, provide the framework for designing and operating facilities that are secure, resilient, efficient, and maintainable. They bring consistency across infrastructure deployments while supporting the critical requirements around uptime, safety, redundancy, scalability, and operational performance.

For many organisations, navigating the complexity of these standards is a challenge in itself, particularly where multiple disciplines intersect across telecoms networks, structured cabling, power systems, cooling, physical security, and critical infrastructure resilience. Interpreting the standards correctly and applying them practically through design, construction, and operation is essential to avoiding compliance gaps, costly rework, and long term operational risk.

Our IT Infrastructure consultants are CNIDP trained, so we translate the relevant BS EN and industry requirements into practical delivery standards and hold them consistently from design through to handover.

The “90 metre rule” in structured cabling refers to the maximum recommended permanent link distance for copper data cabling, as defined within international and BS EN structured cabling standards. In practical terms, this means the fixed horizontal cabling between the telecommunications room and the work area outlet should not exceed 90 metres, allowing up to a further 10 metres for patch leads and equipment connections to maintain the overall 100 metre channel limit. Exceeding this distance can result in signal degradation, reduced network performance, intermittent connectivity issues, and failure to support higher-speed applications such as 10Gb Ethernet or PoE-powered devices reliably. 

The impact of the 90 metre rule extends far beyond the cabling installer and becomes a critical consideration for architects and the wider design team during the early planning stages of a project. Telecommunications room locations, riser strategy, floorplate layouts, ceiling routes, containment pathways, and equipment placement must all be coordinated to ensure compliant cable lengths can be achieved throughout the building. Failure to consider cabling distances during architectural and MEP design can lead to costly late-stage redesigns, additional communications rooms, reduced usable floor space, or compromised network performance and resilience. 

The earlier this is considered the cheaper it is to solve, so we help architects and MEP teams fix communications room locations, riser strategy and containment routes at concept stage, before non compliant cable runs force a late and expensive redesign.

Even within a wireless-first environment, structured cabling remains the critical foundation that enables reliable, high-performance connectivity. Wireless networks ultimately depend on a robust wired infrastructure to connect wireless access points, distributed antenna systems, IoT devices, security systems, AV technologies, and edge computing platforms back to the core network. As organisations increase their reliance on Wi-Fi 6/6E/7, smart building technologies, and real-time digital services, the demands placed on the underlying cabling infrastructure continue to grow, particularly around bandwidth, Power over Ethernet (PoE), resilience, and scalability. 

A wireless-first strategy does not eliminate the need for cabling — it increases the importance of designing the structured cabling correctly from the outset. Access point density, ceiling layouts, containment routes, power requirements, equipment room locations, and future expansion capability all need careful coordination across the wider design team. Poorly planned cabling infrastructure can limit wireless performance, restrict future technology adoption, create operational bottlenecks, and lead to costly retrofit works as wireless demand evolves over time. 

We design the wired and wireless layers as one, sizing access point density, PoE loads and containment so the cabling can carry whatever the wireless estate asks of it now and after the next upgrade.

Selecting the correct IT cabling infrastructure is critical to achieving the required network performance, resilience, and future scalability of a building or campus environment. Different cable categories, such as Cat5e, Cat6, Cat6A, Cat7, and Cat8, are designed to support different bandwidths, transmission frequencies, and application requirements. As network speeds, Power over Ethernet (PoE) demands, and wireless access point densities continue to rise, understanding the performance capabilities and limitations of each cable category becomes essential to ensuring the infrastructure can support both current and future operational needs.

Shielding options also play a major role in overall network reliability and performance. Unshielded (U/UTP) cabling may be suitable for some low interference environments, while shielded solutions such as F/UTP, U/FTP, and S/FTP provide increasing levels of protection against electromagnetic interference (EMI), alien crosstalk, and external electrical noise. The correct shielding approach depends on factors including building services coordination, power infrastructure, containment routes, data centre environments, industrial equipment, PoE loads, and overall installation methodology. Incorrect cable or shielding selection can lead to reduced network performance, increased error rates, overheating risks, compliance failures, and costly future upgrades.

We match cable category and shielding to your actual environment, the interference, the PoE loads, the routes and the lifecycle, so you neither under specify and limit performance nor over specify and pay for protection you will never use.

Choosing between single-mode and multi-mode fibre is a critical decision within telecoms and data centre infrastructure design, as it directly impacts network performance, scalability, transmission distance, and long-term investment value. Multi-mode fibre is typically used for shorter-distance applications within buildings or data centres, offering cost-effective connectivity for lower-distance, high-bandwidth environments. Single-mode fibre, by contrast, is designed for significantly longer transmission distances and higher-capacity applications, making it the preferred choice for campus networks, carrier infrastructure, inter-building connectivity, and future high-speed network evolution.

The decision is rarely based on distance alone. Factors such as current and future bandwidth requirements, active equipment costs, upgrade strategies, pathway availability, resilience requirements, and lifecycle expectations all need to be considered. While multi-mode solutions can offer lower initial transceiver costs, single-mode fibre is increasingly viewed as the more future-proof option due to its virtually unlimited upgrade potential and compatibility with emerging high-speed technologies. Incorrect fibre selection can lead to unnecessary replacement costs, limited scalability, or infrastructure that cannot support future operational demands without significant disruption. With extensive expertise across telecoms infrastructure, fibre network design, and critical connectivity environments, PTS helps organisations make informed, long-term fibre infrastructure decisions aligned to both operational needs and future technology strategies.

We weigh whole life cost rather than just the cable, balancing transceiver prices today against single mode’s near unlimited upgrade headroom, so the fibre you lay still supports your network several generations from now.
