EXFO FTB-5240S-P OSA Optical Spectrum Analyzer 1250-1650nm INB/ADV In-Band OSNR

Condition: Used

Tested and working, bulkhead is in good condition and measurements are within specification. Manufactured in 2014, this FTB-5240S-P module includes both the INB (in-band OSNR) and ADV (advanced measurement mode) options and features an integrated polarisation controller, making it a more capable instrument than the standard FTB-5240S. Compatible with the FTB-200, FTB-2, FTB-2 Pro, FTB-4 Pro and FTB-500 platforms.

Included:
• FTB-5240S-P OSA module (with integrated polarisation controller)
• INB option (in-band OSNR measurement enabled)
• ADV option (advanced measurement mode enabled)
• 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 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.

Key Features:
- Lab-quality, portable optical spectrum analyser
