Fibre Vs Full Fibre Vs Part Fibre Difference

Fibre vs Full Fibre vs Part Fibre: What Is the Difference?

Full fibre reaches your home. Part fibre keeps a copper section.

Published: Updated:

The difference is where the fibre ends

Full fibre

FTTP / FTTH
Exchange or local hubThe optical connection starts here
Fibre distributionFibre continues towards the property
Your homeFibre reaches an optical terminal

No copper telephone cable is needed for the access connection into the home.

Part fibre

Typical UK FTTC
ExchangeFibre carries the first section
Street cabinetThe fibre section ends here
Your homeCopper carries the final section

The length and condition of that copper section affect the speeds available.

Cable broadband

Hybrid fibre-coaxial / HFC
Regional hubFibre carries the connection onwards
Optical nodeThe signal moves onto coaxial cable
Your homeCoax connects to a cable modem

HFC can deliver gigabit services, but coax into the home is different from FTTP.

Simplified access-network routes, not to scale. Intermediate equipment varies. The router and connections to your devices are separate from the incoming line.

So what does “fibre broadband” mean on its own?

It is an incomplete description. Fibre may carry part of the journey without reaching the property. “Full fibre” identifies that final optical connection; in UK consumer terminology, “part fibre” normally describes fibre to a cabinet followed by copper.

In the UK, Ofcom’s guidance took effect on 16 September 2024. Providers should describe the underlying technology clearly before purchase, using terms such as full fibre, part fibre, cable or copper, rather than “fibre” alone.

Check the technology description in the offer and contract summary. A product name, a photograph of a fibre cable or a fast-looking speed tier does not establish what reaches your address. Our part-fibre broadband guide explains the UK FTTC and SoGEA arrangements.

What changes when you move to full fibre?

The useful improvements

  • Broadband no longer relies on the distance-sensitive copper telephone section.
  • The network can support higher speed tiers where the operator and provider offer them.
  • A new fibre installation usually brings an optical network terminal, or ONT, into the property.

What the label does not promise

  • A gigabit subscription. You can buy a slower package over a full-fibre connection.
  • Matching upload and download speeds. Symmetrical service depends on the package and network.
  • Perfect Wi-Fi or the lowest ping to every server. Home equipment, congestion and routing still matter.

For uploads, compare the actual package figures rather than assuming every FTTP offer is the same. Our guide to full-fibre versus FTTC upload speeds looks at that difference in more detail.

Full fibre does not mean fibre to your laptop

Into the property

Fibre reaches the ONT. That is the access connection described by full fibre.

Around the home

The router distributes the connection using Wi-Fi or Ethernet. Those links have their own limits.

Ethernet between an ONT and router does not turn a full-fibre service into part fibre. “Full fibre” describes the line reaching the premises, rather than requiring every internal cable to be optical.

If performance drops in another room, our Wi-Fi vs Ethernet guide helps separate the home network from the broadband connection.

The labels change between countries

Read the underlying technology, especially when comparing international guides.
MarketHow to read the terminology
UKFull fibre usually means FTTP. Part fibre normally means FTTC, with the C standing for cabinet.
USALook for FTTH or FTTP for fibre reaching the premises. The FCC treats fibre, copper/DSL and coaxial cable/HFC as separate access technologies.
AustraliaOn the nbn network, FTTC means Fibre to the Curb, with copper completing the connection from a nearby distribution unit. It is not the same abbreviation expansion as UK FTTC.

FTTH means Fibre to the Home; FTTP means Fibre to the Premises, which can include homes and businesses. Ask where the fibre terminates if the local wording is unclear.

What should you check before choosing?

  1. The technology at your exact address

    Confirm FTTP, part fibre, HFC cable or another connection type. One provider can sell more than one technology.

  2. Both speed figures and the full cost

    Compare the stated download and upload speeds, contract length, setup costs and scheduled increases. A faster headline can hide an unsuitable upload speed or a higher overall bill.

  3. The installation required

    Ask whether an existing connection and ONT can be reused or whether a new cable and engineer visit are needed. Agree where any new wall box and router will go.

I would favour full fibre over part fibre when the price and contract are similar. But I would still compare the actual packages: paying for more speed will not solve a weak wireless signal in a back bedroom.
