Key Features & Specifications

  • Wavelengh Range: 1460 to 1580nm
  • Max. Output Power: + 6dBm (Output2)
  • Max. Tuning Speed: 80nm/s with Dynamic Specifcations
  • Wavelength Accuracy (abs.): ± 10 pm


The Keysight 81680B Tunable Laser Source covers both S- and C- band. It is specially designed for testing critical DWDM passive components.

Keysight "A" Tunable Laser Sources can be upgraded.

The 81680B works in both DWDM bands (S- and C- band). It has continuous sweep through full wavelength range, fast tuning speed with dynamic specification, low source spontaneous emission output for high dynamic range, high power optical output for optical amplifier test, a built-in real-time wavelength meter, mode-hop free tuning over full wavelength range, and Panda type polarization maintaining fiber outputs.
