Full fibre, known technically as fibre to the premises (FTTP), is a broadband connection that runs an optical fibre line all the way to your home. Part-fibre broadband, by contrast, uses fibre to a street cabinet and then existing copper wiring for the final stretch to your property. The key difference is that full fibre has no copper in the path, which is why it generally offers higher and more consistent speeds, including faster uploads, than part-fibre connections.
The short answer is that full fibre is the most capable widely available home broadband technology, because fibre carries data better than copper over the final distance. Part-fibre, often referred to as fibre to the cabinet (FTTC), is still common and can provide good speeds, but the copper section limits it compared with full fibre.
This guide explains the difference in plain terms, why it affects speed and reliability, how to tell which you have, and what it means when choosing a connection. Because availability and the connection at your address vary, confirm what is available to you with your provider.
What does full fibre actually mean?
Full fibre means the fibre-optic line runs directly to your home, with no copper involved in delivering the connection. Fibre carries data as pulses of light, which allows high speeds over long distances without the loss that affects copper. Because the whole path is fibre, full fibre supports the higher speed tiers and tends to be more reliable.
This is different from older broadband technologies that use copper for part or all of the connection. The term full fibre is used specifically to distinguish a complete fibre path from part-fibre connections that mix fibre and copper. When a connection is described as full fibre or FTTP, it means the fibre reaches the premises itself.
Because there is no copper in the final stretch, full fibre is not subject to the distance-related slowdown that affects copper-based connections. This is a large part of why it offers more consistent performance, particularly for uploads, which copper-based connections often limit.
How is part-fibre broadband different?
Part-fibre broadband uses fibre for most of the journey but relies on copper for the final connection to your home. The most common form is fibre to the cabinet (FTTC), where fibre runs to a street cabinet and existing copper telephone wiring covers the distance from the cabinet to your property. A related type, fibre to the curb (FTTC can also be distinguished from fibre to the kerb arrangements), brings fibre closer but still uses a short copper run.
Because copper carries data less effectively than fibre, the copper section limits the speeds part-fibre connections can achieve, and performance can vary with the distance from the cabinet. The further your home is from the cabinet, the more the speed can drop. This is why two homes on part-fibre can have different speeds depending on their distance.
Part-fibre connections are still widely used and can deliver good speeds for many households, but they generally cannot match full fibre, especially for upload speed and consistency. As full fibre expands, more homes are gaining access to a complete fibre path.
How do full fibre and part-fibre compare?
Because the difference is mostly about the final connection, it helps to see them side by side. The table below gives a general comparison, not fixed figures, since performance depends on many factors.
| Feature | Full fibre (FTTP) | Part-fibre (FTTC) |
|---|---|---|
| Path to your home | Fibre all the way | Fibre to a cabinet, then copper |
| Speed capability | Higher tiers supported | Limited by the copper section |
| Upload performance | Generally stronger | Usually more limited |
| Distance sensitivity | Not affected by copper distance | Speed can drop with distance |
The table shows that the absence of copper gives full fibre an advantage in speed, upload performance and consistency. Part-fibre remains a workable option for many homes, but the copper section is the main factor that holds it back compared with a complete fibre path.
How do you tell which you have, and what does it mean for choosing?
If you are unsure which connection type you have, your provider can confirm it. Knowing whether you have full fibre or part-fibre matters because it sets the realistic ceiling for your speeds and shapes whether an upgrade to full fibre is available. As full fibre rolls out, many homes on part-fibre may gain the option to move to it.
When choosing a connection, it is worth understanding that full fibre supports the higher speed tiers and stronger uploads, which suits households with heavy or simultaneous use, while part-fibre may be sufficient for lighter needs. If full fibre is available at your address, it is generally the more capable option, though the right choice still depends on your needs.
Because availability and the connection at your address vary and full fibre is expanding, confirm what is available to you with your provider. They can tell you your current connection type and whether full fibre can be ordered for your home.
Frequently asked questions
Is full fibre the same as fibre broadband?
Not always. The term fibre broadband has been used for part-fibre connections that mix fibre and copper, while full fibre, or FTTP, means fibre runs all the way to your home. If the distinction matters to you, confirm whether a connection is full fibre with your provider.
Why is full fibre faster than part-fibre?
Full fibre has no copper in the path, while part-fibre uses copper for the final stretch, and copper carries data less effectively than fibre. This is why full fibre supports higher speeds and stronger uploads, and why part-fibre speeds can drop with distance from the cabinet.
How do I know if I have full fibre or part-fibre?
Your provider can confirm your connection type. Knowing whether you have full fibre or part-fibre helps you understand your realistic speeds and whether an upgrade to full fibre is available at your address as the rollout continues.
Can I upgrade from part-fibre to full fibre?
Often yes, where full fibre has reached your address, though it depends on availability. Upgrading usually involves a full-fibre installation and may include new equipment. Confirm whether full fibre can be ordered for your home, and what the move would involve, with your provider.
Conclusion
Full fibre (FTTP) runs an optical fibre line all the way to your home, while part-fibre broadband uses fibre to a street cabinet and copper for the final stretch. The absence of copper gives full fibre higher and more consistent speeds, including stronger uploads, while part-fibre can be limited by the copper section and distance from the cabinet. Knowing which you have helps you understand your speeds and any upgrade options. Because availability varies and full fibre is expanding, confirm what is available at your address with your provider.
