This unit
The Agilent/Keysight 8168A is a tunable laser source engineered for optical component and system characterization across the 1550 nm window. It delivers independent control of wavelength and output power with 0.001 nm resolution, enabling precise heterodyne and coherent measurements. A built-in side mode filter ensures true single-mode operation across the entire tunable range, eliminating multimodal interference and supporting fast, accurate wavelength scans with stable, flat power output.

Agilent / Keysight 8168A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 8168A. Calibration covers wavelength accuracy at 5 or more points across the full tuning range, mode-hop-free range, output power flatness, linewidth, and side-mode suppression ratio (SMSR). All calibrations ship with a NIST-traceable certificate. Turnaround is typically 1–3 business days after receipt.
Common Agilent / Keysight 8168A faults: output power drift, mode hops, fiber pigtail connector damage, wavelength inaccuracy. Common faults include output power drift after extended use, mode hops at specific wavelengths, and fiber pigtail connector damage. Full alignment and piezo calibration typically restore performance to spec.
