HP / Agilent 8168F 1480-1590nm Tunable Laser Source (TLS)

The HP/Agilent 8168F is a tunable laser source delivering precise wavelength control across the C-band and extending into the L-band spectrum. Operating from 1480 nm to 1590 nm with ±0.035 nm accuracy and 0.001 nm resolution, this instrument generates stable, single-mode optical output essential for component characterization, system validation, and research applications. A built-in side mode filter suppresses unwanted modes to >50 dB, ensuring clean spectral performance at every wavelength.
