How it Works
Gigabit Passive Optical Network
Understanding HCB’s Network
At HCB, we’ve chosen GPON (Gigabit Passive Optical Network) as our network architecture. In simple terms, GPON is a point-to-multipoint system meaning one main fibre connection from our network can serve many homes or businesses.
The magic happens thanks to passive splitters within our fibre optic distribution network (known as the ODN). These splitters allow a single fibre cable to branch out and reach multiple properties efficiently. Because it’s fibre optic, data travels as light signals through cables giving you ultra-fast, reliable internet.
How the Network Connects
Our headend cabinet (or fibre node) is located just off the A339. This is where everything starts. From here, we connect via our backhaul feed directly to major data centres in London Docklands, often called Telehouses, which link us to the wider internet (WWW).
We’re currently upgrading our backhaul to form part of a circular backhaul loop, connecting to several data centres. This will make our network even more resilient and secure.
From the Cabinet to your Premises
From our headend cabinet, fibre cables run through HCB’s ducts to underground chambers located near villages, hamlets, and clusters of homes. Inside these chambers are splitters, which branch connections out to individual properties.
From the splitter, small ducts are buried to the edge of your property, then routed through your garden to your house. Once we’ve drilled a small hole through your wall and placed your router in a convenient spot (ideally near a power socket), we’ll blow the fibre through the duct to connect your router directly.
Power and Reliability
Our GPON system needs power at both ends, in the headend racks and in your home (for your router). If there’s a power cut, your broadband will stop working unless you have backup power, such as a generator or battery pack.
If you’re a vulnerable customer or have poor mobile reception, we strongly recommend keeping a battery pack handy. You can find suitable options on Amazon for under £100. If you’re unsure which to choose, our Support team is always happy to advise.
Ownership and Responsibilities
HCB owns and maintains the network all the way up to and including your router. If there’s a problem with the connection or the router itself, it’s our responsibility (or that of our contracted ISP) to fix it.
That said, we ask customers to look after their router, avoid damaging it or moving it unnecessarily. Please remember: you’re responsible for everything on your side of the router, such as your internal Wi-Fi network or any connected devices.
