How does broadband work?

Fibre broadband is the next generation of broadband - much faster, more reliable and it uses a different technology. Whilst traditional broadband (known as ADSL) is delivered via copper telephone lines, fibre broadband uses fibre optic cable.

Fibre broadband can be delivered in two ways from the exchange: fibre to the cabinet (FTTC) and fibre to the premises (FTTP).

FTTC uses fibre-optic cables throughout the network right up to the street cabinet. It then uses copper wires to connect the cabinet to homes and businesses. FTTC provides wholesale download speeds up to 80Mbps and upload speeds up to 20Mbps.


FTTP means fibre-optic cables run right to the door of each house or business. It provides wholesale download speeds up to 330Mbps and upload speeds up to 30Mbps.

The project will ensure Suffolk has access to world class broadband speeds of up to 80Mbps by end of 2015. Ultra-fast broadband speeds of up to 330Mbps will also be deployed in certain areas and, as of Spring 2013, anyone in a FTTC-enabled area will be able to upgrade to FTTP ‘on demand’ should local businesses want to upgrade to even faster speeds.

Suffolk will see around £40 million invested to expand superfast broadband throughout the county. This will have the power to transform the life, work and play of citizens across Suffolk. What's more, superfast broadband will boost the economy of Suffolk, enabling businesses to work more effectively in new ways and reach out to new customers.
