Digital communication runs on invisible highways made of copper and glass. Network cabling is what links devices, systems, and users, whether you’re watching a video at home or transferring terabytes in a data centre. But not all cables are created equal. To get dependable connectivity, you need to understand what each type of network cabling offers and where it works best. Let’s go beyond surface-level specs and really dig into the key cabling options, their construction, advantages, and ideal applications.
Despite the rise of wireless tech, wired connections remain the backbone of serious IT infrastructure. Cables deliver lower latency, fewer dropouts, and stronger security.
They’re essential for:
If you’re considering upgrades in a place like Richmond Hill, understanding your options is the first step to getting it right the first time.
Let’s start with the big three: coaxial, twisted pair, and fibre optic. Each has unique properties that make it suited to different environments.
This older technology still has its place. Coaxial cable consists of a single copper conductor in the centre, surrounded by insulation, a metal shield, and an outer jacket. That shield is key—it prevents signal loss from electromagnetic interference.

Variants of Coaxial Cables
Single-core coaxial cable is made to keep signals clear and strong. It has one copper wire in the centre, wrapped in insulation and covered with a metal shield that blocks outside interference. This makes it reliable for important uses like internet connections, security cameras, and cable TV. Because it carries one signal at a time without much loss, it works well in places where a weak signal could cause problems.
Multi-core coaxial cable has several copper wires inside one cable, each with its own insulation, all wrapped together with a metal shield. This lets it carry multiple signals at once, which is helpful for places like TV stations, phone networks, and other systems that need to send lots of data at the same time. Using one cable for many signals also makes installation easier and keeps things tidy.
Coaxial isn’t the top choice for new installations, but it still sees use where durability and shielding are non-negotiable.
Twisted pair cabling is a type of electrical cable made by twisting pairs of wires together. This design helps reduce electromagnetic interference from external sources and crosstalk between neighboring pairs. It is widely used in telecommunications and computer networking, especially for Ethernet cables in local area networks (LANs). There are two main types: Unshielded Twisted Pair (UTP), commonly used in homes and offices, and Shielded Twisted Pair (STP), which has additional shielding to further minimize interference in industrial or high-interference environments. Twisted pair cables are cost-effective, flexible, and easy to install.
The two main types of Twisted Pair Cabling –
Unshielded Twisted Pair (UTP) cables are the most common type used in home and office local area networks (LANs). They consist of pairs of wires twisted together to reduce interference from nearby electrical devices. UTP cables are easy to install, cost-effective, and work well for everyday networking needs where electromagnetic interference is minimal.
Shielded Twisted Pair (STP) cables provide extra protection against electromagnetic interference (EMI). They have an additional shielding layer around the twisted wire pairs, which helps block out noise from nearby electrical equipment. STP cables are ideal for environments with high EMI, such as industrial settings or crowded office spaces, ensuring a more stable and reliable network connection.
This is where most people start—and often where they stay—especially with high-quality Cat6 or Cat6a cabling.
Fiber optic cabling uses thin strands of glass or plastic fibers to transmit data as pulses of light, allowing for incredibly fast and long-distance communication with minimal signal loss. Unlike traditional copper cables, fiber optics are immune to electromagnetic interference and offer significantly higher bandwidth, making them ideal for internet backbones, data centers, and high-performance networks. There are two main types: single-mode fiber, which is used for long-distance transmission, and multi-mode fiber, suited for shorter distances. With light-speed data transmission, fiber optic cabling is the gold standard for modern, high-speed communication infrastructure.
Fibre is more expensive upfront, but the performance gains are unmatched.
Even among fibre optic options, not all cables are equal.
Single-mode Fibre (SMF)
Ideal for: telecom providers, long-range infrastructure
Multi-mode Fibre (MMF)
Ideal for: data centres, corporate LANs, and campus environments
Choose SMF if you’re building for the future and distance is a factor. MMF is more budget-friendly and still fast enough for most commercial use.
Cabling isn’t just about the type—it’s also about the category. Here’s how the categories stack up.
Category | Max Speed | Max Distance | Common Use | Notes |
Cat5e | 1 Gbps | 100 metres | Small offices/homes | Replaced older Cat5 |
Cat6 | 1 Gbps (10 Gbps under 55m) | 100 metres | Office buildings | Less crosstalk, tighter twists |
Cat6a | 10 Gbps | 100 metres | Large enterprises | Shielded, bulkier but better |
Cat7 | 10 Gbps | 100 metres | Data centres | Individually shielded pairs |
Cat8 | 25–40 Gbps | 30 metres | Server rooms | Best performance, most expensive |
Lower categories (Cat1–Cat4) are now obsolete or used in legacy telephone systems only. Cat8 is overkill for home setups but a game-changer for modern enterprise networks.

What are the main types of network cables?
The main types of network cables are twisted pair cables (UTP and STP), coaxial cables, and fiber optic cables. Each offers different benefits in terms of speed, signal range, and interference resistance, depending on the networking requirements and installation environment.
What is the difference between UTP and STP cables?
UTP (Unshielded Twisted Pair) cables lack shielding and are more commonly used in home and office networks. STP (Shielded Twisted Pair) cables have an additional shield that helps reduce interference, making them suitable for environments with high electromagnetic interference.
Why is fiber optic cabling used in modern networks?
Fiber optic cabling transmits data using light, allowing for faster speeds and longer distances than traditional copper cables. It is resistant to electromagnetic interference and is ideal for high-bandwidth applications like data centers and large-scale enterprise networks.
When should coaxial cables be used in networking?
Coaxial cables are mainly used in cable television and older networking systems. Though less common today for data networking, they are still used in specific applications requiring a durable cable with good resistance to signal interference over moderate distances.
Which network cable is best for home networking?
For home networking, Cat5e or Cat6 Ethernet cables are most commonly used. They offer reliable speed, are easy to install, and support typical internet usage like streaming, gaming, and browsing without the higher costs of fiber optic cabling.
How do I choose the right network cabling system?
Choosing the right cabling depends on your needs for speed, distance, and budget. Use UTP for basic setups, STP in high-interference areas, and fiber optics for high-speed, long-distance, or data-intensive applications like enterprise networks or server environments.
