On March 5, 2009, Ciena Corporation (the "Ciena") issued a press release announcing its financial results for its first fiscal quarter ended January 31, 2009. The text of the press release is furnished as Exhibit 99.1 to this Report. The information in this Report shall not be deemed "filed" for purposes of
Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and shall not be incorporated by reference into any registration statement pursuant to the Securities Act of 1933, as amended.

On March 4, 2009, Ciena took action to effect a headcount reduction of approximately 200 employees, representing 9% of its global workforce. Headcount reductions will be implemented across Ciena's organizations and geographies, with the timing and scope of such reductions varying by country based on local legal requirements. These headcount reductions are expected to be completed during Ciena's third fiscal quarter of 2009. As part of this action, Ciena will also close its Acton, Massachusetts research and development facility on or about June 30, 2009. These actions are part of a restructuring plan to reduce operating expense and better align Ciena's workforce, facilities and operating costs with market and business opportunities in light of ongoing difficult macroeconomic conditions. Ciena committed to these restructuring actions on March 2, 2009.

Ciena expects to record aggregate restructuring charges ranging from approximately $5.0 million to $8.0 million associated with this action, all of which will result in future cash expenditures by Ciena. Restructuring charges include severance and other employee-related costs ranging from approximately $3.0 million to $4.0 million. Ciena expects these employee-related restructuring charges to be paid and incurred primarily during the second fiscal quarter of 2009, and to a lesser extent in the third fiscal quarter of 2009. Restructuring charges also include approximately $2.0 million to $4.0 million in facilities-related costs, primarily associated with remaining lease payments for Ciena's Acton, Massachusetts facility. This charge is expected to be incurred during the third fiscal quarter of 2009, with the resulting cash expenditures to be incurred as the remaining lease obligations are due.

On March 5, 2009, Ciena issued a press release which included the announcement of the restructuring plan described above. The text of the press release is furnished as Exhibit 99.1 to this Report.
