EXFO FTB-7500B Series Long-Haul OTDR Module Calibration and Repair Services

Simbol Test Systems provides professional in-lab EXFO FTB-7500B Series Optical Time-Domain Reflectometer (OTDR) module calibration and repair services to help maintain accurate, reliable performance for your fiber optic test equipment. The EXFO FTB-7500B Series consists of single-mode long-haul OTDR modules designed for metro and long-distance optical fiber testing.

The EXFO FTB-7500B Series is used with compatible legacy EXFO mainframes such as the FTB-200 v2, FTB-400, and FTB-500. Common models include the FTB-7523B dual-wavelength module for 1310 nm / 1550 nm testing, the FTB-7534B for 1550 nm / 1625 nm applications, the FTB-7503B and FTB-7504B single-wavelength versions, and the FTB-75-ER03B extended-range model for very long links.

Depending on configuration, these modules may include connector and polish options such as UPC, APC, and interchangeable EXFO Universal Interface (EUI) adapter formats including FC, SC, and LC. If your module shows measurement drift, unstable trace performance, connector wear, communication faults with the host mainframe, or other operating problems, we can review the failure condition and provide service recommendations based on the exact model and suffix 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.
