Managed wavelength services - also known as leased lambda services - offer customers protected bandwidth by using different light wavelengths to provide data channels. The technology will allow service providers to offer flexible, intelligent and protected bandwidth capacity over optical fibre.
Because it avoids the need to lay extra fibre, managed wavelength can offer a cheaper option to leasing dark fibre or private lines.
Philipe Morin, Nortel vice- president of optical Internet technology, said, "Storage area networking is one of the first applications where we will see deployment of this technology. In this rapidly expanding market, an operator can move between protocols, bit rates and technologies without having to buy new circuit switches.
"For existing customers using our newer switches, many of the features are enabled via software up-grades, while older products can receive the benefits of the new wavelength technology through card upgrades."
