SAN JOSE, Calif. -- Oplink Communications, Inc. (Nasdaq: OPLK), designer and manufacturer of innovative optical components and integrated optical modules, today announced the addition of components based on fiber Bragg gratings (FBG) to its product lines. FBG-based components made by Oplink will be used for Dense Wavelength Division Multiplexing (DWDM), intelligent Optical Add Drop Multiplexing (OADM) and Gain Flattening Filters (GFF) as well as optical elements for dispersion compensation, optical monitoring and various other functions. FBG technology is ideally suited for building the tunable filters that are critical to the systems architectures envisioned for future optical networks.

In a second release:Oplink Communications, Inc. (Nasdaq: OPLK), designer and manufacturer of innovative optical components and integrated modules, has introduced a new line of variable optical attenuators (VOAs) for use in optical communications systems. Optical attenuators are essential for adjusting imbalances in optical power distribution across different wavelengths. Optical amplifiers, for example, increase signal strength by different amounts at different wavelengths. An optical attenuator is used to decrease the amplitude of optical signals by precise amounts before or after amplification. Oplink's VOAs offer excellent precision and repeatability. A broad range of wavelengths (e.g. an entire band) can be attenuated from 0.2 dB to as much as 30 dB. Oplink's VOAs are available for attenuation of all optical wavelengths in the C, L and S bands.

In a third release:

Oplink Communications, Inc. (Nasdaq: OPLK), designer and manufacturer of innovative optical components and integrated optical modules, today announced that it has been issued a U.S. patent for its wavelength optical circulator process. Wei Li, Oplink's CTO and Yan Tang, Ph.D., both Oplink scientists, are the inventors of the Optical Circulator patent.

"We believe this is a highly significant patent for Oplink," said Fred Fromm, President, Oplink Communications, Inc. "The process invented by our scientists is a key enabling technology in Oplink's innovative fiber optics solutions."
