Everyone wants faster, more reliable internet. But when it comes to the technology delivering it—Fibre vs. Copper—what’s the real difference? For decades, copper wiring has been the backbone of internet connectivity, transmitting data through electrical signals. On the other hand, fibre optic technology has emerged as a revolutionary alternative, using light pulses to send information at incredible speeds through thin glass strands. Both have their strengths, but understanding how they function can help you choose the right solution for your needs.

What is Copper Internet?

Copper cables have long been used for internet connections, leveraging the flow of electrical signals to transmit data. Common types include Cat5e, Cat6, Cat6a, and Cat7 cables. Cat5e cables, for instance, can support speeds of up to 1 Gbps over distances of 100 metres, while Cat6 cables are capable of reaching 10 Gbps, though their effective range at this internet speed is limited to 55 metres. Cat6a and Cat7 cables build on these improvements, offering enhanced speeds and performance for more demanding applications.

One of the main advantages of copper internet lies in its cost-effectiveness for shorter distances, making it an affordable option for small-scale setups or areas requiring basic connectivity. Additionally, its infrastructure is widely established, particularly in rural or remote areas where fibre optic networks may still be unavailable. Copper cables also remain reliable for less demanding applications, like voice calls and slower internet speeds.

However, the limitations of copper cables are significant. They are highly susceptible to electromagnetic interference (EMI), which can disrupt data transmission. Copper also experiences considerable signal loss, known as attenuation, over longer distances, with up to 94% of the signal degrading after 100 metres. Security is another concern, as copper cables can be physically tapped, posing a risk for sensitive data. Despite these drawbacks, they continue to play a vital role in regions where upgrading to fibre optic technology is not yet feasible.

What is Fibre Internet?

Fibre optic cables are composed of hair-thin strands of pure glass or plastic designed to transmit data in the form of light pulses. This state-of-the-art technology offers significant advantages over traditional copper cables, starting with faster speeds. Since photons, the particles of light, travel near the speed of light, fibre optic cables can achieve exponentially higher bandwidths, with demonstrations of speeds up to 60 Tbps.

Beyond speed, fibre optic cables are remarkably reliable. Unlike copper, they are immune to electromagnetic interference (EMI), resistant to temperature fluctuations, and unphased by environmental moisture. This ensures consistent connectivity and reduces signal degradation, with less than 3% signal loss over 100 metres compared to copper’s 94%. Additionally, the enhanced security of fibre optics is unparalleled; intercepting fibre optic signals is extremely difficult. Any attempt to tap the cables leaks light and disrupts the transmission, making detection almost immediate. Lastly, fibre optic cables excel in transmitting signals over greater distances without the need for a signal booster – many kilometres, in fact.

Fibre optic cables come in two main types, each tailored for different applications. Multi-mode fibre is ideal for shorter distances, such as within a building or across a campus, and supports data rates of up to 10 Gbps over distances of up to 550 metres. On the other hand, single-mode fibre is designed for long-haul connections spanning upwards of 40 kilometres, offering the capability to support extremely high internet speeds, reaching up to 400 Gbps and beyond. These features underline the versatility and performance of fibre optics, making it a critical foundation of modern internet infrastructure.

What About Wireless?

Wireless Broadband

Wireless broadband serves as a third alternative to fibre and copper connections, utilising radio frequencies to deliver internet access. This makes it an ideal solution for areas where laying physical cabling is impractical or too costly. However, wireless broadband does come with limitations. The signal strength tends to degrade with distance from the source, and it can be more susceptible to interference from environmental factors, leading to lower reliability compared to a physical fibre internet connection. Despite these drawbacks, wireless broadband remains a flexible option for connecting remote or hard-to-reach locations.

Cost and Installation: Is Fibre More Expensive?

Initial Costs

Copper-based networks are often more cost-effective for initial setup, especially for short-range applications, thanks to the widespread availability of existing infrastructure. Installing copper cables does not typically require extensive modifications or specialised equipment, making it a more budget-friendly choice in the short term. On the other hand, fibre internet installation can entail significantly higher upfront costs. This is largely due to the skilled labour required for precise cable termination, as well as the trenching and other physical processes needed to lay the cables. These factors make fibre a more substantial investment initially, particularly in areas where infrastructure is not already in place.

Total Cost of Ownership (TCO)

While fibre internet may demand a higher initial outlay, it often proves to be the more economical choice over time due to its lower Total Cost of Ownership (TCO). Fibre optic cables are highly durable, with a longer lifecycle than their copper counterparts, and they are more resilient to environmental wear and tear. Additionally, fibre networks require less maintenance and fewer networking components, which translates to reduced operating expenses. The long-term reliability and lower upkeep costs make fibre a smart economic decision for those looking to future-proof their network infrastructure. Despite the higher upfront costs, investing in fibre can result in significant cost savings over the course of its use.

FAQ

Want to know more about fibre availability and general things?

1
What is optical fibre?

Optical fibre is a hair-thin strand of glass, specifically designed to trap and transmit light pulses. The fibre uses light instead of electricity to carry a signal. It can carry an enormous amount of data over very long distances without buffering or a loss of signal, and it can provide those signals simultaneously for the upload and download of data, without losing speed. Copper networks can carry a fair amount of data, but only for a few hundred meters before the signal begins to fade and buffer.
2
What is the Internet of Things?


Today only 10% of all communication takes place via network devices, like your phone connecting to your Bluetooth speaker. Therefore, 90% of all communication is still on a human to human or human to device level. It is said that in a few years’ time, up to 90% of all communication will occur between devices. Fibre, especially open access networks, gears you for this future.
3
What is the difference between an ISP and a Network Owner such as Lightstruck?


A network owner plans, installs, owns, and operates the physical fibre network in your area. They are solely responsible for the infrastructure. The ISP is in charge of selling the fibre to the public. Your ISP rents your fibre circuit as a utility from companies like Lightstruck and pays a portion of your package price over to the network owner.
4
What does FTTH stand for?




FTTH stands for Fibre to the Home. It refers to the completion of this next generation network right onto your property.
5
What does Mbps mean?


A bit is a common description of a unit of digital data or information. Mbps stands for megabits per second and this normally refers to the physical allocation of your data or “pipe” size. Imagine fibre being a 1m thick water pipe with infinite capacity. Mbps is like putting a tap on that enormous water pipe which will give you a steady flow of, for example, 20 litres per second.
6
Can fibre break?



Fibre that is properly installed will seldom break and can last for 25 – 30 years. Fibre most often breaks due to human interferences such as theft, accidents, or negligence by other utility maintenance teams. If damaged, your fibre can, in most cases, be repaired on the same day.
7
What is the difference between copper and fibre?

Copper internet normally delivers a Digital Subscriber Line or an ADSL service over a standard telephone line that also provides the internet access. Copper is a former generation technology and is not nearly as reliable as fibre. Fibre internet consists of very thin glass strands, as opposed to copper wires, for faster data transfer. There is no comparison between copper and fibre as fibre is superior on all levels.
8
What is a GB?




GB stands for Gigabyte and refers to an allocation of digital information or data. For example, a movie with fair resolution is around 1 GB in size.
9
How does connecting fibre to homes and businesses improve the user experience?

Connecting homes directly to fibre optic networks enables enormous improvements in the bandwidth that can be provided to communities, now and for many decades to come. Fibre is called the end-game technology. 5G and similar connections are still some distance from your property and from thereon everyone competes for the same internet access. Fibre is the only real digital utility that will enhance digital services at home and at work, including video, the Internet of Things, gaming, and smart homes.
10
Will I still need a landline?





No, you can order internet and telephone services directly from any of the accredited ISP’s.
11
What is the difference between capped and uncapped data?



With uncapped data you get unlimited data access at a steady speed. With capped data you are allocated a certain amount of data or GB’s (gigabytes) and when it is depleted you need to buy more to gain further access. The current trend in South Africa is uncapped packages, as it does not restrict users.
12
I stay in a gated estate/multi dwelling unit. How do I get my body corporate/owner association involved?
