Redwood City, Calif. – May 23, 2007 – A newly published report by Dell’Oro Group, the trusted source for market information about the networking and telecommunications industries, reveals that worldwide sales of WDM Optical Transport equipment in the first quarter of 2007 grew 56 percent over the same period last year, driven by strong WDM Metro sales across all regions of the world.

“The exceptional year-over-year growth for WDM Metro was driven primarily by the EMEA region, with Alcatel-Lucent leading all vendors,” said Jason Suey, Analyst for Optical Transport research at Dell’Oro Group. “New services demand is driving equipment purchases for next generation networks.
