What is Fiber Broadband?

Unlike ADSL broadband connections, which use standard copper wires to send data, fiber optic broadband works by sending laser light along a plastic or glass cable – literally at the speed of light. This means that data can be sent and received at much better speeds.

There are two types of fiber broadband, FTTC – Fiber to the Cabinet – being the most common. This connects the fiber cable to the green cabinet in your street, which is then connected to your home with copper wires.

FTTP — or fiber to premises — is where fiber-optic cables run to your property instead of stopping at a street cabinet.

Since copper has no wires, it is also known as ‘full fiber’. This is the fastest type of broadband, but currently only accounts for a minority of UK connections.

What are the benefits of fiber broadband?

Because it’s faster, it provides slicker web browsing, seamless streaming, and a generally more satisfying online experience. Fiber broadband is also much more reliable when multiple members of the same household need to be online at the same time.

How Fast is Fiber Broadband?

According to Ofcom’s regulator, superfast FTTC fiber connections (some with copper wires) provide download speeds of at least 30 Mbps (megabits per second).

Ultrafast FTTP connections (‘full fiber’ straight to your door) provide download speeds of at least 300 Mbps, with some packages offering up to 900 Mbps or even 1 gigabit per second (1,000 Mbps) .

For reference, according to Ofcom, the average broadband speed for the UK is 71 Mbps.

How much does it cost?

Fiber is more valuable than standard broadband, especially for ultrafast speeds via FTTP where a broadband-only package can cost more than £50 per month. There may also be set-up costs to consider. However, FTTP deals don’t require you to have a phone line, which goes some way to offset the expense.

Do I need fiber broadband?

Fiber-optic broadband is ideal for busy, modern families for regularly downloading movies or games or uploading substantial digital files. It is also becoming imperative for domestic workers dependent on high quality video calls.

Can anyone get fiber optic broadband?

This depends on whether your area is serviced with a fiber connection from either of the two main fiber providers – BT Openreach and Virgin Media.

Most broadband providers use the OpenReach network – enter your postcode on the OpenReach Online Fiber Broadband Checker to see if you can get it. Virgin Media has its own postcode checker that you can use to check if your area is serviced.

What if I am not getting fiber yet?

While most households have access to FTTC, FTTP is currently only available in about 15% of households. But that is about to change with government targets set to add more homes.

If your area is not yet serviced, you can register your interest online with BT Openreach. If there is enough demand from other locals who have also submitted interest, BT can get in touch.

You can register for an update with Virgin Media if you currently cannot receive Fiber to your address.

How do I get the best fiber broadband deal?

You have to compare the broadband packages on offer in the same way as with the standard broadband deals. Results can be filtered by cost, but it’s important to remember that it’s not just about price. A cheap deal may not offer the speed or service you are looking for.

You should consider the length of the contract as well as whether you want an ‘unlimited package’, which means you don’t need to worry about download limits.

Also think about the ‘add-on’ elements offered with many fiber broadband packages. These include TV subscriptions, mobile plans and other features that may provide better value than your existing set-up.

Can I switch broadband providers at any time?

You can switch your broadband provider at any time, but you may have to pay a fee for early termination of your contract if you are still in your contract period.

If you’re not sure, check with your provider or ditch your contract to see how much time you have left on it.

If you do end up switching, don’t forget to note when your new deal expires—this will serve as a reminder for you to compare prices again, to make sure you’re on the go. Still on the best deal.

frequently Asked question

What is the difference between fiber and copper broadband?

Using the Internet involves sending and receiving data from your computer or mobile device. Generally speaking, there are two main ways to transmit data: copper (often called ADSL) or fiber optic cables (and sometimes a combination of both). There is also satellite and mobile broadcasting which we look at below.

When transmitted using copper telephone wires, the data is translated and sent as pulses of electricity. Copper is an excellent conductor with relatively low electrical resistance which makes it a good medium for sending and receiving data.

Data sent through fiber optic cables moves at the speed of light resistance free. This makes transmission much faster than copper broadband.

Copper broadband can transmit data at up to 24 megabits per second (Mbps). In contrast, fiber broadband can reach speeds in excess of 1,000Mbps (1Gbps), making it 40 times faster.

A hybrid copper and fiber connection type known as fiber to the cabinet (FTTC) uses copper cable from an exchange to the nearest roadside cabinet and then to your home. Speeds are significantly faster than copper alone, topping out at around 80 Mbps.

Fiber to the home (FTTH) or fiber to the premises (FTTP), however, uses fiber optics from the exchange to your home. It offers the fastest possible broadband connection with speeds of over 1Gbps.

What factors affect my broadband speed?

Other factors, as well as your connection, will determine your home broadband speed.

For example, wired connections can generate faster speeds than wireless ones. The more devices connected to your router, the slower your speeds are likely to be.

Some factors are out of your control. For example, the distance between your home and the house…
