EXFO BRT Series BRT-320 / BRT-320A Optical Return Loss Test Set Calibration and Repair Services

Simbol Test Systems provides professional in-lab EXFO BRT-320 and BRT-320A optical return loss (ORL) and back-reflection test set calibration and repair services to help maintain accurate, reliable performance for your fiber optic test equipment. The EXFO BRT Series is a legacy family of field-ready instruments used for optical return loss and back-reflection measurement in fiber optic network testing and component evaluation.

The EXFO BRT-320 and EXFO BRT-320A are commonly used where stable, repeatable ORL measurements are required for fiber links, passive components, and installation verification. These platforms remain relevant for customers maintaining legacy fiber test workflows and established field service procedures.

If your unit shows measurement drift, reduced ORL accuracy, source instability, connector wear, display or control issues, or other operating problems, we can review the failure condition and provide service recommendations based on the exact 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 BRT-320 or BRT-320A and a brief description of the issue to request a calibration quote or repair evaluation.
