Ultrafast fibre – G.FAST

G.fast is exclusive to a selection of UK towns and covers almost two million postcodes as of Nov 2018. Our totally unlimited 160Mbps and 330Mbps G.fast is perfect for users who are otherwise unable to receive FTTP and don’t have the budget to move to an Ethernet product.

The technical bit

With conventional broadband, the broadband modem connects to the Digital Subscriber Line Access Multiplexer (DSLAM) in the local exchange. Since an exchange can be many kilometres away, the signal from the broadband connection could have to travel along very long lengths of a copper cable; limiting the connection speeds.

G.fast was developed to bring the DSLAM even closer to residential and businesses premises (generally within 250 metres) by deploying DSLAM-equipped distribution points, which are connected to BT’s network using fibre. This allows G.fast to provide:

1. much higher peak speeds than FTTC (fibre) broadband

2. a solution for buildings located quite some distance from a fibre street cabinet, where FTTC speeds would be substantially lower than 80 Mbps download and 20 Mbps upload.
