Frequently Asked Questions
- What does the Exfo FTB-5240S-P measure and what are its key specifications?
- The FTB-5240S-P is an Optical Spectrum Analyzer module that measures optical power across the C-band and L-band wavelength range from 1250 nm to 1650 nm, with a dynamic power range of −70 dBm to +23 dBm. This module is engineered for high-resolution spectral analysis in DWDM and CWDM system testing, spectral component characterization, and general optical communication measurements. It integrates seamlessly into EXFO's modular FTB platforms—the FTB-200, FTB-500, and FTB-5240—making it suitable for both field deployment and laboratory environments.
- What is the condition of this used Exfo FTB-5240S-P, and what has been verified?
- This unit is sold in used condition and has been functionally inspected to confirm operational status. We verify core measurement functionality and mechanical integrity before listing, ensuring the module powers on and responds to control commands within the stated performance envelope. As with all used test equipment, cosmetic wear may be present, but the optical and electronic components meet working standards for immediate deployment.
- Is calibration available for the FTB-5240S-P, and what does it cost?
- Yes, NIST-traceable calibration is available as a separately ordered service starting at $450, which covers the optical power measurement path and wavelength reference accuracy. Calibration certification documents the module's conformance to published specifications and is recommended for quality assurance and regulated applications. Lead time and detailed scope of calibration work can be provided upon request through our service team.
- What interfaces and connectivity options does the FTB-5240S-P support?
- The FTB-5240S-P connects to its host FTB platform via a proprietary module slot interface and inherits the platform's control connectivity—typically GPIB, USB, and Ethernet, depending on the chassis model. Software control is managed through EXFO's instrument drivers and platform software suite, which support remote automation and data logging for system integration. Consult the host platform's documentation for specific interface availability and driver compatibility with your operating environment.
