High Resolution Optical Spectrum Analyzer AP206x Series


AP206x Series
Ideal solution for Telecommunication applications, the Optical spectrum analyze (OSA) AP206x Series is equiped with the high resolution of 20 MHz/0.16 pm, as well as other resolution bandwidth from 140 MHz to 250 GHz. Thanks to the two polarization channels inside, analysis of optical signal in different polarization axis is possible.

Available options:
– the optical output of the built-in Tunable Laser Source (TLS), which could also be used for component analysis (tracking funciton);
– replace the Resolution BandWidth of 20 MHz by 5 MHz 


  • Resolution from 250 GHz to 140 MHz, up to 20 MHz/0.16 pm High Resolution
  • 3 models : C Band / L Band / C&L Band
  • Dynamic range 78 dB
  • Rectangular-shape resolution filters
  • 2 channels, one per polarization axis
  • Built-in tunable laser source
  • Component transmission/reflection analysis
  • 5 MHz resolution optional
