Internet service provider (ISP) Colt has become the first company in Europe to carry out a successful field trial of 100Gb Ethernet technology.
The firm, which is working in conjunction with Infinera, transmitted a signal over an 861km route between London and Frankfurt - the continent's two largest financial centres.
Constructed using Infinera's DTN optical platform, and designed to deliver ultra-fast broadband services to business telecoms users, the line was completed in August 2010.
A prototype 100Gb Ethernet client interface was used for the pilot, fully compliant with the industry standard IEEE 802.3ba ratified in June 2010.
Colt said the successful trial "further demonstrates the capability of the fibre network to support new, high-speed services".
The firm's Chief Technology Officer Luke Broome said the development of next-generation optical transport technologies must continue, ensuring customer demand for high-speed Ethernet services can be met.
Earlier this month, Colt announced the launch of Application Aware Networking Services through a partnership with Ipanema Technologies.
