 Fastest Multi-Wavelength Meter: 438 Series

The 438 Series Multi-Wavelength Meter combines proven Michelson interferometer-based technology with fast Fourier transform analysis in order to measure the wavelength, power, and OSNR of as many as 1000 discrete optical signals. With features such as high accuracy, a measurement rate of up to 10 Hz, and a broad operational range from 1000 to 1680 nm, the model 438 provides the most precise, efficient, and versatile WDM wavelength testing to satisfy the needs of any manufacturing engineer.
