This unit
The Agilent 81689B is a compact C-band tunable laser module engineered for optical testing and measurement applications in DWDM systems. It delivers a stable, precise optical source across the entire C-band, enabling flexible test configurations for optical amplifiers, DWDM components, and related optical subsystems. The module supports both internal and external modulation with continuous sweep capability across its full wavelength range, and operates within Agilent's modular lightwave measurement platforms.

HP / Agilent 81689B — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the HP / Agilent 81689B. 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 HP / Agilent 81689B 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.
