OSA150 Fast Spectrum Analyzer

The Southern Photonics OSA150 Fast Spectrum Analyzer is a low-cost, high-speed instrument that yields highresolution spectral measurements.

The OSA150 exhibits a 10dB improvement in the Optical Rejection Ratio (ORR) parameter when compared to conventional Fabry-Perot filter-based OSAs. This improvement in ORR makes the OSA150 an ideal candidate for real-time measurement of closely-spaced DWDM channels in your laboratory or manufacturing facilities.

OSA150 Fast Spectrum Analyzer Specifications

  • Bandpass Resolution : 2.5GHz (24pm)
  • Wavelength Repeatability : 0.3GHz (2.4pm)
  • Sensitivity : -55dBm
  • Dynamic Range : 70dB
  • Optical Rejection Ratio (@100GHz) : 40dB
  • Polarisation Sensitivity : < 0.3dB
  • Wavelength Range : 1500-1580nm
