BT Superfast Fibre

BT Superfast Fibre (formerly BT Infinity) is a broadband service in the United Kingdom provided by BT Consumer, the consumer sales arm of the BT Group. The underlying network is fibre-to-the-cabinet (FTTC), which uses optical fibre for all except the final few hundred metres (yards) to the consumer, and delivers claimed download speeds of "up to 76 Mbit/s" and upload speeds of "up to 19 Mbit/s" depending on package selected.[1] The fibre terminates in a new roadside cabinet containing a DSLAM, from where the final connection to the customer uses VDSL2 technology.

Ofcom data gathered in November 2014 indicated that only 1% of 76 Mbit/s and 15% of 38 Mbit/s customers received the advertised speed.[2] It adopted its present name on 23 May 2018 as part of BT's renaming of its entire broadband portfolio which is "designed to be simpler and more descriptive".[3]
