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