In general the optical market continues to show "lumpiness" with Q2 and Q4 being the larger quarters, and Q1 and Q3 being down or slow quarters in nature.
IDC continues to see huge growth in the metro WDM market, which was up 51% year over year, demonstrating the strong demand for ROADM in core regional networks as well as the emerging access segment. The Metro WDM market was strongest across North America and EMEA this past quarter, with Tellabs and Nortel taking share in North America.
Notable increases for Q1 2008 go to Fujitsu and Tellabs, reflecting the early AT&T purchasing this year and continued Verizon deployments. In a down quarter, both vendors were up quarter over quarter, as well as year over year. Ciena while up slightly over last quarter, has done remarkably well year over year.
This quarter Tellabs has recognized revenues from its 7100 Optical Transport Systems, and shipped and taken first place in the ROADM market of Metro WDM with 43% market share. With Fujitsu not far behind climbing to 22% market share in a huge quarter for them, mostly due to AT&T.
Cisco has held relatively flat quarter over quarter. We believe a large segment of its ROADM goes to enterprise deployments, and at IDC, we expect Cisco will do something (M&A?) to jump into this growing market to meet service provider demands, which are clearly reflected on the success of Fujitsu and Tellabs to date.
AT&T and Verizon have been clear they are spending huge amounts of money in the next few years on regional metro and long haul optical deployments.
