81640A Tunable Laser Source

Overview and Features Wavelength Range: 1510nm to 1640nm Max. Output Power: 4dBm Wavelength Accuracy (abs.): ±0.015nm Wavelength repeatability (typ.): ±0.5pm The Keysight 81640A tunable laser source covers both C- and L - Band. It is specially designed for testing critical DWDM passive components. This Keysight "A" Tunable Laser Source has been replaced by 81640B but can be upgraded. The 81640A works in both DWDM bands (C- and L-Band). It has continuous sweep through full wavelength range, low source spontaneous emission output for high dynamic range, high power optical output for optical amplifier test, a built-in real-time wavelength meter and mode-hop free tuning over full wavelength range.
