Fibre broadband technology explained
Understanding fibre to the home technology
There are three main types of broadband that link the local exchange to your house:
- ADSL (asymmetric digital subscriber line), using copper cables to a street cabinet and then more copper to your house
- FTTC (fibre to the cabinet), using fibre cables to a street cabinet but then copper cables to your house
- FTTH (fibre to the home), using only fibre cables to your house
Copper has been the backbone of the internet for many years, it’s used across the UK and goes into most homes, but it is old and slow.
Fibre optic cables are made from glass and use pulses of light to transmit data at much higher speeds. So, the more fibre used in a network, the higher the speed.
A fibre only connection, like our FTTH service, delivers the highest speeds, symmetrically into homes.
Your Wi-Fi Router Explained
Your hyperfast fibre broadband needs to reach all your devices and users, wherever they are in your home. Fundamental to that is your Wi-Fi and to maximise Wi-Fi performance we work with Zyxel, a market leader in Wi-Fi technology.
The Zyxel VMG8825-T50 gigabit internet access device provides high performance and flexibility for full fibre to the home broadband consumers.
With built-in 4×4 802.11ac WLAN function it offers great coverage and Wi-Fi user experience, with features including:
- VDSL2 supporting super vectoring up to profile 35b.
- AC2400, dual-band Wi-Fi with 802.11ac 4×4 Wave 2 technology.
- Supports VoIP SIP protocol with 3-way conference calls.
- USB 3.0 high throughput for file sharing.
- Excellent routing and QoS capability to prioritise applications.
- NAT, firewall with SPI and DoS for better security.
- Stand-alone and wall mountable.
Core hardware features:
- WAN: One 10/100/1000 Mbps Ethernet port RJ-45
- DSL: One RJ-11
- Ethernet: Four 10/100/1000 Mbps ports RJ-45 (8P8C)
- Wireless: Three internal antennas (2.4 GHz) and four internal antennas (5 GHz)
- VoIP: 2 FXS ports
- USB: One USB 3.0 host and One USB 2.0 port
Digital Home & IP address allocation explained
Digital Home runs a modern fibre to the home network which supports hyperfast broadband. As we move to IPv6 addressing next year, that is metaverse orientated, cloud first digital services, some things will be left behind. As a result, Digital Home does not provide publicly available IP addresses for any specific subscriber or connection.
This means that if you are running home network servers that depend upon port forwarding and static IP address routing requirements, our network is not right for you.
There are providers out there who may provide this to you as a business or premium service option.
There are ways to “enhance” your home network with cloud based server options using VPN’s which will work over our network. As the world migrates to IPv6 this is the likely future, so join us there and enjoy our speed and great service.

Hyperfast Broadband Speed Examples
Wondering how long it takes on our hyperfast broadband vs what you currently experience? No problem – take a look.
|Activity||Assumed file size||Digital Home up to 900 Mbps broadband||UK average broadband|
|Time to download an HD TV show||450MB||8 seconds||56 seconds|
|Time to download an HD movie||4GB||72 seconds||500 seconds|
|Time to download a video game||50GB||888 seconds||6,240 seconds|
UK average download 64Mbps (Ofcom May 2020).
Digital Home download 450Mbps.
The times shown above have been calculated using the estimated file size associated with each activity but the actual speeds you experience may vary based on several factors, including but not limited to traffic on your current network and the strength of your Wi-Fi connection.
Broadband speeds explained
We provide broadband speeds of up to 900 Mbps symmetrically to every home, but let’s talk honestly about the most important thing – the speed you actually experience on your devices.
That speed depends on several things but mainly on how your devices are connected to your broadband service.
We would expect a wired device, that has the specification to cope with 900 Mbps, using the correct cables, to experience speeds of between 500 & 600 Mbps, depending on device locations.
Wi-Fi performance however is susceptible to real life variables including the construction materials of your home, your everyday home items, your PC and your neighbours!
