儀器介紹
The Agilent 81642A tunable laser covers the C- and L- Band. It is optimized for testing optical amplifiers at high stimulus power, and passive components. This Keysight Agilent HP "A" Tunable Laser Source has been replaced by Agilent 81642B but can be upgraded. The Agilent 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.
