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

Condition: Used

Tested and working unit with good bulkhead condition and measurements confirmed within specification. Manufactured in 2010, this FTB-5240S-P module includes the INB in-band OSNR option and is compatible with FTB-200, FTB-2, FTB-2 Pro, FTB-4 Pro, and FTB-500 platforms. The integrated polarisation controller makes this a significantly more capable instrument than the standard FTB-5240S for coherent network testing.

Included in the sale:
• FTB-5240S-P Module (with polarisation controller)
• INB option (in-band OSNR measurement 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 with integrated polarisation controller
- Wide spectral range covering O, E, S, C and L bands
- High optical rejection ratio (ORR) for accurate DWDM channel measurements
- In-band OSNR (INB) measurement option for coherent systems
- One-button operation with intuitive touchscreen graphical interface
- Internal and external calibration capability
- Compatible with FTB-200, FTB-2, FTB-2 Pro, FTB-4 Pro and FTB-500 platforms
- Rugged field-ready modular design
