Sycamore Networks Inc. said the Nasdaq has granted its request for continued listing.
The company, a Chelmsford maker of optical switches used to build fiber-optic networks, is investigating its past stock-option granting practices. It said the decision is subject to its filing of delayed reports for the fiscal year ended July 31 and its fiscal first quarter, as well as any restatements, by March 14.
Sycamore must also provide the Nasdaq with additional information regarding its options investigation by March 2.
Sycamore is one of at least 107 companies under scrutiny by the Securities and Exchange Commission or Department of Justice over possible backdating of stock-option grants.
