Sky broadband customers are now able to take advantage of a 100Gb optical network, enabling them to rapidly download large files.
BSkyB has launched the new service - supported by Alcatel-Lucent - as it upgrades its capabilities across the board.
The network uses Bell Labs silicon innovations to support data speeds of 100Gb on each of the 88 wavelengths of an optical fibre.
Consumers can use the network to download HD movies, music and other content faster than ever before.
Mohamed Hammady, Director at Sky Network Services, said millions of Sky customers use the firm's broadband network to enjoy video and other high bandwidth services.
The network is free from any form of traffic management, he explained.
"We can do this because of the investment we make in our state-of-the-art, all-fibre core trunk network," Mr Hammady stated.
Sky recently launched a new broadband deal offering 12 months' half-price internet services and home phone calls.
