Why Good Cabling Matters
In today’s connected world data centres are the backbone of everything from business to schools and shops. Key components such as the cabling system are crucial for seamless connectivity and operational efficiency in data flow management.
At the heart of these complex systems is something often overlooked: the cabling. Good cabling isn’t just about connecting devices. It’s the nervous system of your entire network, that affects how well it performs, how reliable it is and how easily it can grow. And accounting for future requirements in the design of data centre cabling infrastructure is essential for scalability and future upgrades and expansions.

What is a Data Centre?
Data centres are the heart of modern businesses, housing and managing the critical infrastructure for data storage, processing and transmission. These facilities are critical for network availability, reliability and performance, to provide a service to users across all sectors.
A well designed data centre infrastructure is critical for data transmission and minimising downtime. This means careful planning and design of the data centre facility itself, for optimal energy efficiency, sustainability and scalability. Data centre management is key to business continuity, minimising losses and overall service quality.
Data centre management is about optimising resources, including computing resources, storage systems and cabling infrastructure to deliver services reliably. A data centre strategy must consider multiple sites, multiple paths and future expansion requirements to provide reliability and avoid costly downtime.
The installation of data centre infrastructure must be meticulously planned and executed to minimise disruption to services and optimal energy efficiency. Data centre infrastructure must be designed with future expansion in mind, considering issues such as cooling systems, power consumption and connectivity.
By investing in a well designed data centre infrastructure businesses can ensure reliable and efficient data transmission, minimise downtime and provide a high quality service to users. This investment supports current operations and prepares the business for future technological advancements and growth.
Understanding Structured Cabling
Structured cabling (aka structured data cabling) is an organised approach to designing and installing network cabling systems. Unlike messy “spaghetti cabling” that connects points directly, structured cabling follows organised methods and industry standards to create a system that’s cohesive, scalable, and easy to manage.
The main difference between structured and unstructured cabling is organisation and future-proofing. While unstructured cabling might seem cheaper at first, the long-term costs of maintenance, troubleshooting, and replacement make structured cabling the better investment for any serious organisation.
Key Parts of a Structured Cabling System
A good structured cabling system has several important subsystems working together:
- Entrance Facilities – Where external service provider networks connect to your internal network
- Equipment Rooms – Dedicated spaces for core network equipment like servers and switches
- Backbone Cabling – High-capacity connections between equipment rooms, typically using fibre optic cables
- Horizontal Cabling – Runs from telecommunications rooms to individual workstations, usually through ceilings or under floors
- Telecommunications Rooms – Distribution points for horizontal cabling
- Work Area Components – End-user connection points including wall plates and patch cables
Cabling Solutions
Different environments require different cabling solutions based on performance needs, distance limits and environmental factors.
Copper Cabling:
Cat5e: Up to 1 Gbps, common in existing installs
Cat6: 10 Gbps short distance, good for most businesses
Cat6a: 10 Gbps with better noise resistance, modern offices
Cat7: Higher frequencies with fully shielded construction for special needs
Fibre Optic Cabling:
Fibre optic cabling has better bandwidth and distance capabilities, single-mode fibre for long distances and multimode (OM3, OM4, OM5) for shorter distances.
For data centres, MTP/MPO systems offer high density fibre solutions, multiple fibre connections in one connector and easy upgrades as needs grow.
Choosing the right cabling depends on many factors, your needs, environmental conditions, distance limits and budget. At RJ Electrical Contractors we help clients find the right solution for their situation
Best Practices
Planning and Documentation
Good cabling starts with planning. Before you even start installation, site surveys are done to assess the existing infrastructure, physical space and requirements. This information is used to create detailed documentation of the entire cabling system.
Key Planning Points:
Site surveys and infrastructure assessment
Cable types, pathways and termination points
Consistent and consistent labelling
Forward-thinking
Following industry standards and regulations
This is the most important but often overlooked part of a successful implementation. The time spent on planning pays off during the installation and the life of the infrastructure.
Physical Layouts and Cabling
Physical organisation is key to performance and maintenance. Racks and cabinets are strategically placed to reduce cable lengths and airflow to cool the equipment which is important for equipment life and energy efficiency.
Power cables and data cables are kept separate to prevent interference that can degrade network performance. Cable support systems including cable trays, ladders and support mechanisms prevent cable stress and maintain bend radius to ensure signal integrity long term.
The physical layout also considers environmental factors such as temperature control, humidity management and access security all important parts of a robust data centre.
Performance Optimisation Tips
Maximum network performance requires more than just choosing the right cables:
- Cable Selection – Based on application, environment and distance
- Termination Techniques – All connections must meet industry standards for signal integrity
- Testing and Certification – All installed cables must meet or exceed spec
- Environmental Considerations – Temperature, humidity and EMI
- Future Proofing – Choose cabling that exceeds current bandwidth
Using metrics to measure performance is key. MTBF, signal quality and packet loss help you gauge the overall performance of your network.
With attention to these performance factors you can build a network infrastructure that delivers today and has room to grow and adapt to future technologies.
