How Fibre Broadband Works

Rinky Dink Inc

Welcome to the world of lightning fast internet speeds with fibre broadband. Reliable and super fast, fibre broadband has revolutionised data transfer across devices and networks. This is all thanks to it its special fibre cable technology.

While traditional ADSL (asymmetric digital subscriber line) and ADSL2+ broadband users have connection and download speeds of up to 24 Mbps, the copper telephone line technology, used in ADSL broadband, cannot achieve the lightning-fast connection speeds, possible with fibre broadband technology.

Whether using your laptop, smartphone, tablet or using your smart TV, fibre broadband gives you high powered connection, with speeds of up to 330 Mbps, and as as high as 40 Gbps in some circumstances.

The special fibre technology gives more bandwidth, allowing you to use all your devices at once, at super-fast internet speeds. So, how does fibre broadband really work?

How Fibre Broadband Works

To give you super-fast connection speeds and very high band widths, fibre broadband uses fibre optic cables, which are specially designed cables that are able to transfer data as light signals, at lightning speeds.

Fibre optic cables have very thin, hair-like fibre tubes, which are made of plastic and glass. These fibre wires are reflective on their inside, and it is this property that enables them to transfer digital data through the fibre cable.

Using infrared laser light, fibre wires transfer digital data as flashes of light, which reflects on their inner walls and bounces through the cable. These flashes of light are then interpreted by a computer as data.

Why Choose Fibre Broadband Over Traditional ADSL?

In traditional ADSL and ADSL2+ broadband, data is transferred through copper telephone lines from a telephone exchange, to the premises being connected.

While ADSL achieves impressive connection speeds of up to 24 Mbps, the copper telephone lines cannot achieve speeds of up to 330 Mbps, possible with fibre optic cables.

The condition of telephone wire transferring data signals and the distance of premises from the broadband provider, lead to loss of signal when using ADSL broadband, resulting to slow connection speeds.

The loss in signal also results in interference, when connecting using traditional ADSL broadband.

Fibre optics are not affected by any signal loss or interference when transferring data. While connection speeds reduce with increasing length of the copper transmission wire, in ADSL broadband, fibre broadband superior connection speeds are not affected by distance.


You can get a fibre broadband connection either as Fibre to the Cabinet (FTTC), or Fibre to the Premises (FTTP), all depending on your budget, connection preference and availability.

The majority of the connections in the UK have been done using FTTC connection, which is more commonplace in the UK.


FTTC is the most common fibre broadband connection with Openreach broadband providers, and it has the widest reach in the UK, partly due to its cost, ease of installation and existing telephone infrastructure.

Broadband providers install a fibre optic street cabinet and link it to the exchange using a fibre optic cable. The fibre optic street cabinet is then linked to your house or business 200 to 300 metres away, using the existing copper telephone line.

Signal loss and interference is eliminated between the exchange and the street cabinet, connected through a fibre optic line. And, data from the street cabinet is transmitted over a short distance to your house or business, though a copper line. This gives you high and improved connection speeds of up to 76 Mbps.

To achieve its high connection speeds, FTTC Fibre broadband connection uses VDSL2 (Very High-Speed Digital Subscriber Line 2), as opposed to using traditional ADSL technology.


For ultra fast internet connection, internet users prefer FTTP fibre broadband connection, as it is an all fibre connection eliminating any signal loss or slowed speeds.

FTTP fibre broadband connection, uses a fibre optic line connection from the exchange to your home or business. There is no signal loss or interference due to an all fibre optic line connection, leading to speeds of up to 330 Mbps.

Coming with a high cost of installation, and with existing infrastructure favouring FTTC connection, FTTP use is limited, but the speeds it gives are worth the cost, and its demand has been steadily rising.

Getting The Best In Fibre Broadband

Many fibre broadband providers in the UK provide FTTC Fibre broadband connection relying on the BT Openreach network, and the existing telephone infrastructure. However, one fibre broadband provider stands out with an own dedicated fibre broad band connection network.

Virgin Media, does not use existing telephone lines but uses a dedicated network of high-quality coaxial cables for connections from the fibre street box to your home or business.

Data transfer through coaxial cables is faster than a copper telephone line, with little signal loss, which has seen Virgin Media's fibre broadband connection achieve speeds of up to 200 Mbps.

Virgin Media has been able to double its fibre broadband connection speeds, through the use of an own dedicated network. And, since Virgin Media is not limited by existing telephone lines, it can also install a land-line free fibre broadband connection for your home or business.

So, if you are looking for the fastest internet for, working online, streaming catch-up TV, downloading your favourite movies, or online gaming, Virgin Media's dedicated connection network ensures you have the fastest connection possible.
