The keysight 81680A tunable laser source is specially designed for testing critical DWDM in C-Band.
The keysight tunable laser source marked "A" has been replaced by the 81680B, but can be upgraded.
Features
Designed for C-Band
Continuous scanning over the entire wavelength range
High dynamic range source with low spontaneous emission output
Optical amplifier for testing high power fiber output
Built-in real-time wavelength meter
Mode-hopping-free adjustment over the entire wavelength range
Both fiber outputs are equipped with Panda-type polarization maintenance fiber.
