Simbol Test Systems provides professional in-lab EXFO FOT-920 Series MaxTester optical loss test set (OLTS) calibration and repair services to help maintain accurate, reliable performance for your fiber optic test equipment. The FOT-920 Series MaxTester is a rugged handheld automated loss test set designed for fiber optic network installation, maintenance, and high-volume field testing.

The EXFO FOT-920 Series MaxTester is widely used for single-mode and multimode fiber validation, making it a practical solution for link verification and routine field testing. Although this is a legacy discontinued platform, it remains popular on the secondary market due to its durability, portability, and straightforward operation.

If your unit shows measurement drift, inconsistent loss readings, connector interface wear, power-related faults, or other operating problems, we can review the failure condition and provide service recommendations.

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.
