Looking ahead, Tellabs said it expected revenue in the next quarter to be "flat to up by a mid-single-digit percentage." In early July, Tellabs announced plans to slash 150 jobs, or cut about 5% of its work force, in a Securities and Exchange Commission filing. The company said the restructuring plan is likely to be completed by the end of the second quarter in 2010. Within minutes of the opening bell Monday, the stock was changing hands down 3.6% to $5.56. --David Moss reported this story from New York City.
