Showing Results for Keysight Technologies (Agilent HP) 8168F

The HP 8168F is a 1550nm, +7Bm, tunable laser source. It is equipped with a built-in sidemode filter to ensure true single-mode operation over the full wavelength range. Output power and wavelength are selectable independent from each other. Wavelength scans, which require an output power that is stable over time and flat across all wavelengths, can be performed reliably, accurately, and quickly.
