The Keysight (Agilent HP) 8168F is a high-performance tunable laser source operating in the 1550 nm band (1450 nm to 1590 nm range). Engineered for demanding optical component testing, it features a built-in sidemode filter to guarantee true single-mode operation across its entire tuning range. It allows independent control of output power and wavelength, enabling stable and flat wavelength scans. Its versatile sweep and modulation capabilities make it ideal for characterization of passive and active optical devices.
