Metro Holdings, the joint venture between three European telco powerhouses, has completed construction of three London fibre rings.
These cover Broadgate in the City, Canary Wharf in Docklands and Aldgate in east London.
The company was set up by Deutsche Telekom, France Telecom and Energis in April and has been dismissed by rivals as a "construction firm". It will spend #100 million over five years, initially building a network in London.
Metro's next phase will see three further rings covering the remaining major business districts in the capital.
