Advantest Q8331

Multi-Wavelength Meter
In recent years, WDM communication systems have been growing bandwidths with shrinking
wavelength spacings and increasing numbers of wavelengths. Accordingly, high accuracy measurements of wavelengths and power levels
of multiplexed optical signals are required.
In addition, demand exists in telecommunication systems for an instrument that can measure modulated as well as unmodulated CW (Continuous Wave) optical signals. The Q8331 Multi Wavelength Meter satisfies all of these requirements with high speed, and
high accuracy measurements.
