# 81640A Agilent Fiber Optic Equipment Used

**Additional Features:**

-   Wavelength Range: 1510nm to 1640nm
-   Max. Output Power: 4dBm
-   Wavelength Accuracy (abs.): ±0.015nm
-   Wavelength repeatability (typ.): ±0.5pm

The Agilent 81640A tunable laser source covers both C- and L - Band. It is specially designed for testing critical DWDM passive components. This Keysight Agilent HP "A" Tunable Laser Source has been replaced by Agilent 81640B but can be upgraded. The Agilent 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.
