Keysight Agilent 81651A 1550 nm Laser Source Module Calibration and Repair Services

Simbol Test Systems provides professional in-lab Keysight (Agilent / HP) 81651A 1550 nm laser source module calibration and repair services to help maintain accurate, reliable performance for your fiber optic test and measurement systems. All calibration services are performed in our laboratory using documented procedures, traceable standards, and experienced technical staff.

The 81651A is a high-performance single-wavelength Fabry-Perot laser source module designed for fiber optic and telecommunications network testing. Operating at a center wavelength of 1550 nm, it is used in Agilent and Keysight 816xB lightwave mainframes to provide stable optical output for loss testing, component evaluation, and general optical system measurements. If the module exhibits output instability, wavelength-related performance issues, connector wear, communication faults with the mainframe, or other operating problems, we can evaluate the condition and provide appropriate service recommendations.

Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the module does not successfully complete calibration, we can evaluate the repair requirements and provide a repair quotation for approval before proceeding.

Traceability: Instrumentation used during this calibration is traceable to N.I.S.T. (National Institute of Standards and Technology) or C.N.R.C. (Canadian National Research Council), where applicable.

Contact Simbol Test Systems with your module model number, mainframe type, and a brief description of the issue to request a calibration quote or repair evaluation.
