Compact tunable laser, C+L band, 1520-1630nm, up to 13dBm

Manufacturer's part number :


Manufacturer Agilent Technologies

Keysight Technologies

Description :

Keysight's 81949A high power compact tunable laser enables optical device characterization at high power levels and measurement of nonlinear effects. It improves the testing of all types of optical amplifiers and other active components as well as broadband passive optical components. As single slot plug-in modules for Keysight's 8163A/B, 8164A/B and 8166A/B mainframes, they are a flexible and cost effective stimulus for single channel and DWDM test applications. Each module covers a total wavelength range of 110 nm in the C+L-band.

  • Quote and availability


  • High optical output power: +13 dBm
  • Wide tuning range: 1520nm-1630nm
  • Absolute wavelength accuracy +/-100pm
  • Built-in coherence control
  • Stimulated Brillioun scattering suppression
  • Benefits

  • 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 wavemetre 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
