Principais recursos e especificações

  • Maximum Number of Laser Lines Input: 100
  • Wavelength Range: 700 – 1650 nm (182 to 428 THz)
  • Absolute Accuracy ±3 ppm (±0.005 nm at 1550 nm, ±0.004 nm at 1310 nm) for laserlines separated by 30 GHz


Keysight's Multi-Wavelength Meter family 86120B is the right, optimized tools to efficiently develop, manufacture, install and verify optical components and networks for next generation applications. Keysight multi-wavelength meters are Michelson interferometer-based instruments that measure wavelength and optical power of laser light over a specified wavelength range. Simultaneous measurements of multiple laser lines are performed allowing measurements of DWDM signals and multiple lines of Fabry-Perot lasers.


  • Wavelength scan in less than 1sec
  • Wavelength accuracy: +- 3 ppm for laser lines separated by > 30GHz
  • High Laser Input power: 10dBm (18dBm - Safe Input level)
  • Built-in HeNe laser wavelength standard


  • The wavelength accuracy gives you the certainty of accurate channel characterization in dense WDM systems, to detect channel's wavelength shift and crosstalk between adjacent channels.
  • The high input power level enables you to test transmitter without additional connections and instruments (e.g. attenuator).
  • The built-in HeNe guarantees an accurate absolute wavelength measurement real-time determined against the standard anytime and ensures accurate and reproducible experimental results.
