Fibre Broadband Explained



Fibre broadband is available to around 96% of UK households. It can help you to get a faster, more reliable broadband connection. Something that many of us are looking for when we’re working from home and turning to the internet for our entertainment. Fibre broadband can deliver speeds of up to 1 Gbps. A far cry from the limitations of ADSL broadband which tops out at around 10 Mbps. But what exactly is fibre broadband? Is it available in your area? How does it compare to other types of broadband? And why is there such huge variation in costs and speeds between different providers and deals? Fibre broadband is clearly the future of our online connectivity in the UK, with copper ADSL lines being phased out by 2025. But can you get the best deal for your money with fibre broadband in 2021? Here, we’ll explain everything you need to know about fibre broadband.
Last update: August 2022

What is Fibre Broadband?

Fibre broadband uses fibre optic cables instead of the copper wiring that makes up our phone lines and facilitates ADSL connections. Signals are able to travel much faster through an optic fibre cable compared to copper cables. This means that fibre connections are capable of achieving up to 1,000 times the bandwidth of copper connections.
However, not all fibre broadband connections are created equal. There are different types of fibre broadband connections, and the one you choose will determine both the cost and performance of your fibre broadband deal.

What is the speed of fibre optic internet?

Fibre optic cables are designed to transmit data at close to the speed of light. This means that it is capable of speed ranges that far eclipse those of copper connections. You can see the kinds of speeds that can be obtained by fibre broadband in the table below:

Connection Type Speed Range
ADSL 10-11 Mbps download 1 Mbps upload
Fibre To The Cabinet 30-80 Mbps download 10-20 Mbps upload
Fibre To The Premises 100 Mbps-1Gbps download Symmetrical upload

Types of fibre broadband

There are two types of fibre broadband. Although fibre broadband is available to 96% of households, not all types of broadband are available throughout the country. However, as the country’s fibre infrastructure grows, the chances are getting better and better that you can get a fast and reliable fibre broadband connection.
Let’s look at the different types of fibre broadband…

Fibre to the Cabinet (FTTC)

Fibre to the Cabinet (FTTC) uses a combination of fibre and copper cables to get your household online. This is the most commonly available form of fibre broadband, but it’s not without its caveats.
The speeds and reliability that you experience will be based on your proximity to the cabinet / exchange, and how many others share your connection. Indeed, if fibre broadband is extremely popular in your area, you may find that there isn’t space for you in the cabinet. FTTC broadband is theoretically capable of download speeds up to 200Mbps. This should be more than fast enough for most households.
Getting FTTC broadband means that you will still require a phone line, whether you use it or not.

Fibre to the Premises (FTTP)

Fibre to the Premises (FTTP) is the fastest form of broadband available. This gets a direct fibre connection to your home, ensuring much faster speeds and the most reliable connection possible. Unlike a FTTC connection, you won’t have to worry about reduced performance during peak times as you won’t share a connection with others in the cabinet.
FTTP broadband is capable of ultrafast speeds of up to 1Gbps. However, it is not available in all areas or from all suppliers. Only around 14% of households can currently get FTTP.

What is full-fibre?

“Full-fibre” is another name for Fibre To The Premises. It means that you’re able to get a direct fibre connection to your property.

How does fibre broadband work?

As we can see, fibre broadband by far outperforms traditional ADSL broadband that relies on copper cables. But how does it work?
The cables that deliver fibre broadband consist of fibre optic tubes, each of which is about as thick as a human hair. These transfer data by sending flashes of light through the tubes. These bounce off the inner walls of the cable. Equipment at the receiving end then interprets the flashes as data. This technology enables the data to travel at literally the speed of light.

What other types of broadband can you get?

Fibre broadband is fast-becoming the UK’s favourite way to connect to the internet. However, there are other options if fibre is not available in your area.
ADSL broadband, which uses your existing phone line, is available to most households across the UK. Some suppliers like Virgin Media offer connection to their own network via coaxial cable. This is capable of speeds that are comparable to fibre.
If you live in a rural area with no cabling infrastructure, you may want to consider a mobile broadband or a satellite broadband connection. This uses the same 3G/4G network as your smartphone. This is an affordable option for many, however, it often comes with restrictive download limits.

Where is Fibre Broadband offered?

Fibre broadband is available to 96% of UK households… at least in theory! However, you may find that if you live in an area where FTTC broadband is very popular, you may find that there isn’t enough space in the cabinet to accommodate you.
The good news is that as Openreach slowly phases out ADSL cabling, fibre is getting rolled out with renewed vigour in 2021. Meaning that no matter where you live, there’s a better chance than ever that you’ll be able to get

There are lots of tools available to help you check the availability of fibre broadband in your area. However, the one we recommend is provided by the communications watchdog Ofcom. You can check it out here. Just input your postcode and it will show you which options are available in your area.

Why can't I get fibre broadband?

While fibre broadband is available to most of the country, there are some barriers that may prevent you from getting a fibre connection in your home.
These include:

  • Living in an older property that cannot support the cabling needed for fibre broadband
  • Living in a remote / rural area that has no fibre optic cabling
  • Living too far away from the nearest cabinet
  • There being no room in the nearest cabinet to accommodate your connection because fibre broadband is very popular in your area
  • The landscape around your home prohibits the installation of fibre optic cabling

    Can I get fibre without phone line rental?

    Most fibre broadband deals include phone line rental. This is because they are FTTC deals. You need to rent a phone line for FTTC, even if you have no intention of using a landline telephone. You can only get fibre without phone line rental if you get FTTP.

    How affordable is fibre?

    The average broadband bill in the Uk is around £30. However, it’s possible to get fibre broadband for less than this. Virgin Media, for instance, offers Ultrafast fibre broadband capable of over 100Mbps for £24 per month.

    What’s the difference between superfast, ultrafast and gigabit broadband?

    As fibre broadband, particularly FTTP, becomes more widely available, we’re seeing the boundaries pushed in terms of the speeds that can be achieved. This, in turn has given rise to superfast, ultrafast and even gigabit broadband deals. But are these distinctions just marketing speak, or do they have meaningful implications for your broadband connection?
    The distinction here is the speeds of which the different connections are capable:

    • Superfast fibre broadband is capable of average download speeds between 35-67 Mbps. The upper limit for superfast broadband is 300 Mbps.
    • Ultrafast is any connection with speeds over 300 Mbps.
    • Gigabit broadband is capable of speeds of up to 1 Gbps (1,000 Mbps). Only FTTP connections are capable of achieving this.

    What’s the difference between standard broadband and fibre?

    Standard or ADSL broadband relies on the copper wires in your conventional phoneline. This can bottleneck the speeds of which your connection is capable. Fibre broadband is much faster, with data transmitted at literally the speed of light.

    What’s the difference between FTTP broadband and FTTC?

    Fibre To The Cabinet (FTTC) means that you share a fibre connection with others in your area. This means that your performance may fluctuate depending on how many other users are online at the same time. Fibre To The Premises (FTTP) is a direct fibre connection to your home. The latter is capable of speeds of 1GB and the most reliable connection money can buy.

    How do I install fibre optic broadband?

    If you’re getting a new fibre connection, you’ll need the help of an engineer to install fibre broadband. An installation fee may or may not apply, depending on the length of your contract which could vary from a no-contract plan to 24 months. The engineer will set up your new connection to the nearest cabinet, and install a smart hub / router into which you’ll be able to plug in any wired devices, and broadcast your WiFi signal. In the case of FTTP installations, the engineer will replace your master socket and install an Openreach modem.

    Do I need fibre optic broadband?

    Although ADSL broadband is suitable for most households, speeds usually peak at around 10Mbps. As such, fibre optic broadband is the best choice for those who:

    • Want to stream video from several devices simultaneously
    • Want to stream / live stream in 4K UHD
    • Need to upload large files regularly
    • Rely heavily on video conferencing when working from home

Good article. Is superfast better than ultrafast?


Hello Lauren. Thanks for the questions. Ultrafast is definitely faster than superfast broadband. However in terms of if it´s better, this all depends on your budget, location and household needs.
