OTTAWA -- Nortel Networks (NYSE:NT) (TSE:NT.) today announced general availability of its ML-20 tunable laser, the industry's first Telcordia-qualified widely tunable laser product. Qualification and general availability of the ML-20 are significant achievements, demonstrating Nortel Networks leadership position in innovation and delivery of next generation optical networks. "Achieving Telcordia qualification with a generally available, widely tunable laser serves to reassure carriers of the reliability of this technology," said Vladimir Kozlov, senior analyst, RHK. "The ML-20 makes it possible to remotely provision, route and manage individual wavelengths in order to allocate bandwidth to specific routes in line with demand, and may motivate system equipment providers to offer tunability as an option in current systems.
