AboveNet Expands its Metro-Wave Service with Nortel

LONDON, 26^th July, 2007 – AboveNet Communications UK Ltd., a leading provider of fibre optical connectivity solutions for business and carriers and a subsidiary of AboveNet Inc., today announced its expansion of Metro-Wave, a service offering AboveNet customers private wavelengths between strategically placed hubs in and around London. Utilising Nortel’s Optical Metro 5000 series equipment, AboveNet is extending Metro-Wave connectivity to a new hub in Slough.

Leveraging its experience in building and managing dedicated Wavelength Division Multiplexing networks, AboveNet has built its Metro-Wave network to connect the major business districts in London. By offering managed wavelengths to each customer, AboveNet is enabling many more companies to benefit from managed connectivity services supported by a secure and scalable next generation network.

Having recently expanded to Park Royal, AboveNet’s Metro-Wave footprint will now span from the Docklands in the east through the City, out to Heathrow and Slough in the west. AboveNet uses dedicated fibre to extend the reach of Metro-Wave from enabled sites directly to customer locations. This allows companies to implement disaster recovery, storage, hosting and business continuity strategies which avoid or complement traditional Telco infrastructures.

The simplicity of this network design means AboveNet is able to offer customers short lead-times for service provisioning as well as a scalable, flexible service supporting multiple protocols up to 10Gbps.

“Our proven Optical Metro 5000 equipment enables AboveNet to quickly and confidently deploy new services and locations in line with growing market demand,” said Tony Bailey vice president UK & Ireland Channels, Nortel. “Our equipment, combined with AboveNet fibre, provides AboveNet’s Metro-Wave customers affordable scalable capacity and supports virtually any protocol with proven levels of performance and reliability. This, in turn, allows AboveNet to meet customer requirements today, while providing a scalable platform for both AboveNet and its customers in the hyperconnected future.”

AboveNet has been working with Nortel and the Optical Metro 5000 platform for over seven years and AboveNet is an accredited Nortel Solutions Partner.

“I am extremely pleased with the continued development of our Metro-Wave service,” said John Dowbiggin, managing director of AboveNet Communications UK Ltd.  “I am certain that this extension will only serve to grow our existing Metro-Wave customer base. Moreover, it will further emphasise AboveNet’s commitment to listening to our customers and developing services in line with their networking requirements.”
