Ando / Optical Spectrum Analyzer / AQ6331 
The AQ6331 is a portable optical spectrum analyzer (OSA) with the high performance required for 50 GHz and 100 GHz DWDM network testing. In both the C and L bands and beyond, wavelength rans is 1200 nm to 1700 nm. The AQ6331 is compact, yet has all the features required for DWDM system evaluation. Further, it has excellent wavelength resolution, with accuracy and dynamic range equal to that of any conventional bench-top OSA used in research and development applications.
