ANAHEIM -- Oplink Communications, Inc. (Nasdaq:OPLK), designer and manufacturer of innovative optical components andintegrated optical modules, today introduced a 50 gigahertz (50 GHz)thin-film filter (TFF) based Dense Wavelength Division Multiplexing(DWDM) product line.The primary application for the new 50 GHz TFF-based subsystems isoptical add-drop modules (OADMs) for next generation optical networks. ATFF diverts one narrow band of frequencies (one narrow range ofwavelengths) within an optical add-drop module, allowing differentwavelengths to be selectively routed within an optical network.Using 50-GHz filters, Oplink can build OADMs that selectively add ordrop a data channel from a multiplexed stream of narrowly-spacedchannels that differ in length by only 0.4 nanometers (0.4 nm).

“Oplink is working to be the supplier of choice for the designers ofoptical networking equipment,” said Fred Fromm, President, Oplink. “Wework with the designer from concept to prototype through volumeproduction and will not rule out any technology necessary to deliver theperformance our customers want.”
