Tunable Laser Source

The Keysight 81960A sets a new mark in compact tunable laser performance with faster sweep speeds and repetition rates combined with the dynamic accuracy specifications needed for DWDM component measurements. Dynamically specified sweeps in both directions enhance the repetition rate even further for real-time use in adjustment and calibration procedures. The Keysight 81960A’s dynamic wavelength accuracy will satisfy the test needs for many DWDM components at an optimized performance/price balance. The source to spontaneous noise ratio is sufficient to qualify the isolation of many filter devices.Features： 1505-1630 nm wavelength range±10 pm wavelength accuracy during sweeping200 nm/s maximum scan speedMore than 2 repetitions per second with bidirectional sweepingBuilt-in coherence control, Stimulated Brillouin Scattering (SBS) suppression
