EXFO LTS-3900 Series Optical Loss Test Set Calibration and Repair Services

Simbol Test Systems provides professional in-lab EXFO LTS-3900 Series optical loss test set (OLTS) calibration and repair services to help maintain accurate, reliable performance for your fiber optic test equipment. The EXFO LTS-3900 Series is a legacy line of benchtop optical loss test sets designed for high-accuracy testing in laboratory, manufacturing qualification, and demanding field engineering environments.

The EXFO LTS-3900 Series includes configurations such as the LTS-3902 and LTS-3903, with variants tailored to different fiber test requirements and detector types. Depending on the model, these instruments may be used for optical loss, power, and optical return loss (ORL) measurements in single-mode or other application-specific test setups. Although this is a discontinued legacy series, these instruments remain widely used on secondary markets due to their reliability and continued usefulness in established test benches.

If your unit shows measurement drift, reduced accuracy, detector-related issues, connector wear, interface faults, or other operating problems, we can review the failure condition and provide service recommendations based on the specific model and 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 LTS-3900 Series model number and a brief description of the issue to request a calibration quote or repair evaluation.
