Tunable Laser Source

The Keysight 81642A tunable laser covers the C- and L- Band. It is optimized for testing optical amplifiers at high stimulus power, and passive components.The 81642A works in both DWDM bands (C- and L-Band). It has continuous sweep through full wavelength range, high power optical output for optical amplifier test, built-in real-time wavelength meter, mode-hop free tuning over full wavelength range, and both optical outputs are equipped with Panda type polarization maintaining fiber.Features：Wavelength Range: 1510nm to 1640nmMax.Output Power: + 7dBmWavelength Accuracy (abs.): ±0.015nmWavelength repeatability (typ.): ±0.5 pm
