81940A Agilent Optical Generator

The 81940A is a optical generator from Agilent. Engineers use optical signal generators when they want to transmit optical signals during an electronic equipment test. This tool makes coherent optical signal generation possible using complex quadrature modulation, or the smart combination of multiple phase and amplitude modulators.

 Additional Features:

  • High optical output power: +13 dBm
  • Wide tuning range: 1520nm-1630nm
  • Built-in wavemeter for excellent accuracy: +/-20pm
  • Built-in coherence control
  • Stimulated Brillioun scattering suppression
  • Provides the stimulus power needed to test today's optical amplifiers, which reduces the need to add booster amplifiers.
  • The wide tuning range of 110nm allows characterization of the DUTs in adjacent wavelength bands C+L with one sweep.
  • The built-in wavemeter eliminates the need for external wavelength monitoring, which reduces measurement uncertainties.
  • The built-in coherence control feature avoids problems with stimulated Brillioun Scattering (SBS) and interference effects generated by unwanted cavities
  • Test non-linear effects in fibers and transmission links
