Request A Quote


The Keysight (formerly Agilent) 81600B is a tunable laser source, which offers versatility coupled with good performance. The device’s fast and accurate sweep across the entire wavelength range characterizes advanced optical components with high precision. Signal output with low spontaneous emission (SSE) allows measurement of filters with a very high dynamic range. Some key features and specifications of the Keysight 81600B tunable laser source are:

  • Highest measurement range through low spontaneous source emission (low SSE), Signal to SSE Ratio >70 dB/nm
  • Variable sweep speed up to 80 nm/s
  • Wide tuning range units to cover all transmission bands: 1260 nm – 1640 nm
  • Built-in wavelength meter with excellent wavelength accuracy /-3.6 pm
  • High optical output power up to 9 dBm with built-in high performance 60 dB attenuator
