AE8500 Optical Spectrum Analyzer

The AE8500 is a high precision, high-resolution optical spectrum analyzer with measurement wavelength range of 1250 to 1650nm. Users can test optical signals with excellent accuracy, and the 12.1″ LCD touchscreen and concise UI design make the AE8500 easy to master. It also provides customizable CWDM/DWDM testing, in-band OSNR, light source, EDFA, fiber probe, auto testing, and more. The AE8500 meets the optical spectrum analysis requirements for several years to come – at superior cost-performance.

Overview Main Features
Brought to you by Deviser Instruments, Inc., the AE8500 is a high-precision diffraction-grating OSA with a wavelength range of 1250 ~ 1650nm and power sensitivity down to 70dBm.
Users can test optical signals with excellent accuracy, and the 12.1″ LCD touchscreen and concise UI design make the AE8500 easy to master. It also provides a powerful suite of test modes, including WDM system testing, EDFA, transmittance and drift testing, and semiconductor laser spectrum scans (DFB & FP).
The AE8500 offers exceptional stability and reliability, high-speed spectral sweeping, and multiple ways to output and analyze
your data. It’s the ideal tool for CWDM/DWDM and FTTH project maintenance.
  • FTTH network deployment and maintenance
  • Distributed feedback laser (DFB) and Fabry-Pérot (FP)
  • Analyze single- or multi-λ input: power, bandwidth, drift, SMSR, OSNR, and mode spacing
  • Erbium-doped fiber amplifier (EDFA) Before/after optical amplification; measure PSSE, PASE, gain, and noise factor
  • CWDM/DWDM project acceptance and maintenance
  • Resolution BW up to 60 picometers to test closely-spaced channels – critical for DWDM test aggregation
  • Measure channel power, offset, and OSNR
