Lightwave Equalizer satisfies the ever-increasing demands for spectrum design and dynamic spectral control in WDM optical communications. It is suitable for the applications such as dynamic gain control of EDFAs, gain flattening filter design, and active equalization of signal power for your system experiments, Fiber Optic Interferometers (Mach-Zehnder, Michelson, Ring and Sagnac) can be used for fiber optic experiments and sensors.
