Sky is carrying out limited technical tests of fibre to the cabinet networks in east London.
The broadcaster, which has operated unbundled BT networks to provide DSL services in recent years, is said to be experimenting with extending optical fibre from exchanges to kerbside cabinets.
The networks could potentially be used to provide faster broadband than is commonly available in the UK, or television services.
Sky told the Mail On Sunday the tests did not signal a change in strategy but were "a few men in white coats making a technical study with no commercial involvement".
