This unit
The Keysight 81949A is a tunable laser source module delivering precise wavelength control across the C and L bands (1520 nm to 1630 nm). This plug-in instrument generates up to +13 dBm output power with ±100 pm absolute wavelength accuracy and mode-hop-free tunability across its full 110 nm range. Built-in coherence control, SBS suppression, and an integrated wavemeter (±20 pm accuracy) enable demanding single-channel and DWDM test applications in telecommunications and optical networking environments.

Agilent / Keysight 81949A — Repair & Calibration Service
Aumictech offers NIST-traceable calibration and repair for the Agilent / Keysight 81949A. 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 81949A 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.
