EXFO FTB-5240S-P OSA Optical Spectrum Analyzer 1250-1650nm ADV Measurement Mode

Condition: Used

Tested and working; bulkhead is in good condition and measurements are confirmed within specification. Manufactured in 2013. This unit includes the ADV option enabling advanced measurement mode, and features an integrated polarisation controller making it a significantly more capable instrument than the standard FTB-5240S — particularly suited to coherent DWDM network analysis. Compatible with FTB-200, FTB-2, FTB-2 Pro, FTB-4 Pro and FTB-500 platforms.

Included in the sale:
• FTB-5240S-P Module (with integrated polarisation controller)
• ADV option (advanced measurement mode — active/licensed)
• FC connector

The EXFO FTB-5240S-P is a lab-quality, field-portable optical spectrum analyser (OSA) module designed for comprehensive analysis of CWDM and DWDM optical networks. Housed within EXFO's modular FTB platform ecosystem, it combines high-accuracy spectral measurement with an integrated polarisation controller, enabling advanced in-band OSNR characterisation of polarisation-multiplexed coherent transceivers — including 40G and 100G systems — where traditional out-of-band OSNR methods are unreliable.

The ADV (Advanced Measurement Mode) option expands the instrument's analytical capabilities, and the INB (In-Band OSNR) option leverages the polarisation controller to resolve true signal OSNR on live channels, making the FTB-5240S-P essential for commissioning, maintenance and troubleshooting of modern coherent optical networks.
