EXFO FOT-90 Series Optical Power Meter Calibration and Repair Services

Simbol Test Systems provides professional in-lab EXFO FOT-90 Series optical power meter calibration and repair services to help maintain accurate, reliable performance for your fiber optic test equipment. The EXFO FOT-90 Series is a legacy family of professional handheld optical power meters used for optical power and loss measurements in fiber optic network installation, testing, and maintenance.

The EXFO FOT-90 Series includes multiple detector-based variants for different network applications. Common models include the FOT-91 / FOT-91A with a Silicon (Si) detector for short-wavelength multimode testing, the FOT-92 / FOT-92A with a Germanium (Ge) detector for general-purpose telecom and local network use, and the FOT-93 / FOT-93A with an Indium Gallium Arsenide (InGaAs) detector for higher-performance single-mode fiber testing.

If your unit shows measurement drift, reduced accuracy, connector interface wear, display or control issues, or other operating problems, we can review the failure condition and provide service recommendations based on the specific model configuration.

Following calibration, your equipment may be returned with a calibration label, calibration certificate, and related calibration data. If the unit 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 EXFO FOT-90 Series model number and a brief description of the issue to request a calibration quote or repair evaluation.
