Product Code: AP208x
Manufacturer: APEX Technologies

Top of the line APEX High-Resolution Optical Spectrum Analyzer (OSA), the AP208x Series is equiped with the high resolution of 5 MHz/0.04 pm, 20 MHz/0.16 pm, 100 MHz/0.8 pm, as well as other resolution bandwidth from 140 MHz to 250 GHz. Analysis of optical signal in both polarization axis is possible due to the two polarisation channels inside.  Thanks to the external-cavity tunable laser source inside, the scan speed is much faster than other model.


Available options:



  • the optical output of the built-in Tunable Laser Source (TLS), which could also be used for component analysis (tracking function);

  • additional PM inputs for each polarization channel;

  • optical filtered ouput + polarimeter;

Features:

  • Resolution from 250 GHz to 140 MHz, 100 MHz/0.8 pm, 20 MHz/0.16 pm, 5 MHz/0.04 pm;
  • Available for C+L Band/extended C+L Band/O Band
  • Dynamic range 83 dB for C+L Band, 79 dB for O Band
  • Close-in dynamic range >60 dB @ +/-0.4 pm
  • Rectangular-shape resolution filters
  • 2 channels, one per polarisation axis
  • Built-in tunable laser source
  • Component transmission/reflection analysis
  • Fast sweep

Applications:

  • Advanced modulation format analysis
  • Comb generator measurement
  • Laser characterisation
  • OSNR measurement
  • OFDM analysis
  • Optical sensor/component characterisation

Data handling:

  • USB connectors
  • Ethernet
  • GPIB connector
  • Sensitive screen
