BT Full Fibre is an advanced Fibre to the Premises (FTTP) technology that uses the Openreach fibre network. Openreach is a wholly owned subsidiary of BT, there are actually over 688 service providers that use the Openreach network, among them Sky, BT, Vodafone and TalkTalk.
Unlike the conventional Fibre to Cabinet (FTTC) connections, where fibre optic cables only run to the local street cabinet and the rest of the journey to your home is completed by copper cables, Full Fibre ensures that the fibre optic cable runs all the way to your home or business premises. This continuous fibre optic connection significantly reduces signal loss and latency issues associated with copper cables, delivering ultrafast and reliable broadband speeds that can keep pace with the increasingly digital demands of today’s world.
BT’s Full Fibre portfolio includes a range of packages designed to cater to varying internet needs, striking a balance between speed and affordability. These packages are Full Fibre 100, Full Fibre 300, Full Fibre 500, and the top-tier Full Fibre 900. Each package number represents the average download speed offered (in Mbps), though the actual speeds often surpass the advertised numbers.
Full Fibre 100, for example, provides speeds up to 150Mbps, more than enough to support streaming, gaming, and multiple devices for smaller households. On the other hand, Full Fibre 900, with speeds reaching up to 900Mbps, is perfect for larger households or businesses with extensive online activities and multiple simultaneous users.
The launch of these Full Fibre packages marks BT’s assertive entry into the ultrafast broadband market, rivalling long-standing players known for their high-speed offerings. But it’s not just about speed; BT Full Fibre also stands out for its robust performance and consistent speeds, even during peak times. This is possible thanks to the BT Stay Fast Guarantee, which ensures you receive the speeds you’ve been promised, or you’ll receive compensation.
By pioneering Full Fibre broadband, BT is reshaping the digital landscape of the UK. It’s a game-changing move that makes the dream of giga fast internet a reality for many, redefining expectations for speed, reliability, and quality in the broadband market. In the forthcoming sections, we’ll delve deeper into the workings of Full Fibre technology, its installation process, and the benefits that BT Full Fibre users can expect to reap.
Figure 1 explains BT Full Fibre succinctly. While the theoretical limits of copper are quite high (around 1 gigabit per second) the signal on copper cable internet deteriorates over time which slows down your broadband connection substantially.
Effectively, the longer the stretch of copper cable to your house (or office) the slower your broadband connection becomes. Fibre in contrast maintains the integrity of the signal even over long distances.
But for some time now it’s been a bit of a hybrid (see “traditional fibre” in Figure 1). Traditionally fibre has run from the local BT exchange to a street cabinet. It then transitions back to the copper before entering your house.
That slows the signal down in a similar way to traditional copper broadband. What makes BT’s Full Fibre different is that the fibre line runs directly from the local BT Exchange straight to your house. This is known as FTTH (Fibre to the Home).
Understanding the journey of BT Full Fibre to your home helps appreciate the technological innovation and infrastructure involved in delivering this ultrafast, reliable broadband service.
This end-to-end fibre optic journey, from the central office to your home, provides the backbone for BT Full Fibre, ensuring a highly reliable, ultrafast broadband service for you to enjoy.
It depends on a number of things, not least the package you chose which currently comes with 3 distinct bandwidths Full Fibre 100 (around 150mpbs), Full Fibre 500 and Full Fibre 900. Prices do change over time. We’ve dedicated a page discussing BT’s full fibre pricing and the variations over time to give you a better picture of this.
BT Full Fibre, also known as BT Fibre to the Home (FTTH), is a high-speed broadband service that harnesses fibre optics to deliver superfast internet directly to your home. Unlike traditional broadband services that use copper cables for at least a portion of the data journey, BT Full Fibre uses fibre optic cables throughout, from the local exchange to your premises.
ADSL (Asymmetric Digital Subscriber Line) technology, one of the earliest forms of broadband, provides internet access by transmitting digital information via existing copper telephone lines. However, due to its reliance on ageing infrastructure, it often offers slower speeds, especially for users located further away from the telephone exchange.
FTTC (Fibre to the Cabinet) is a step up from ADSL. In this setup, fibre optic cables run from the telephone exchange to street cabinets, and then the existing copper lines are used to connect the cabinet to households. While VDSL offers significantly higher speeds than ADSL, the speed can still degrade with the distance between the home and the street cabinet.
The advent of FTTH (Fibre to the Home), also known as FTTP (Fibre to the Premises), has been a game-changer. It involves running fibre optic cables directly into your home or business. This technology offers the fastest and most reliable broadband service, as it is capable of handling high-bandwidth applications with ease, and isn’t subject to the same level of signal degradation over distance as copper-based technologies.
Among the providers of FTTH technology, BT Full Fibre stands out. Offering ultrafast and reliable broadband service, BT Full Fibre leverages the full potential of fibre optic technology. It ensures an exceptional online experience, whether for streaming high-definition content, playing data-intensive online games, or connecting multiple devices simultaneously. As we delve deeper into this guide, we will explore the specific advantages and setup of BT Full Fibre, giving you a comprehensive understanding of this revolutionary broadband technology.
Fibre optic cables work by transmitting data as pulses of light, which allows them to carry much more information at much higher speeds than traditional copper cables. BT Full Fibre can provide ultrafast download and upload speeds, significantly enhancing your online experience. This allows for smoother streaming, faster downloads, and better performance for online games. It also ensures reliable connectivity for multiple devices, a vital aspect in today’s connected households.
Furthermore, BT Full Fibre’s use of FTTH technology means that the service is not impacted by the distance between your home and the local telephone exchange, a factor that can significantly reduce speeds in ADSL and VDSL broadband services. In essence, with BT Full Fibre, you get a dedicated, direct line of high-speed internet right to your home.
Traditional broadband, known as Fibre to the Cabinet (FTTC), uses fibre optic cables to deliver data from the service provider to local street cabinets. From these cabinets, copper cables transmit the data the rest of the way to individual households. While fibre optic cables can handle massive amounts of data at high speeds, the copper cables used for the last stretch to homes limit the overall speed and stability of the connection.
FTTP, also known as Full Fibre, changes this by extending the fibre optic cables all the way from the service provider to the user’s home or business. This means that the data doesn’t have to switch from fibre optic to copper midway, eliminating the speed and reliability issues that copper cables can cause.
Fibre optic cables use light signals to transmit data, which is a faster and more efficient method of data transmission compared to the electrical signals used in copper cables. This allows for gigabit-level speeds that are several times faster than those achievable over copper cables. Furthermore, fibre optic cables are less prone to interference and signal degradation over long distances, providing a more stable and reliable connection.
FTTP’s capacity for higher speeds and greater reliability is a game-changer for broadband technology, offering unparalleled connectivity that can handle the most demanding online tasks. Whether you’re streaming ultra-high-definition content, gaming online, working from home, or running a server, BT’s Full Fibre broadband, powered by FTTP technology, is designed to provide the speed and stability you need.
