The EXFO FTB-5500B is a Polarization Mode Dispersion (PMD) analyzer module engineered for the EXFO FTB-500 platform, delivering fast PMD characterization across ultra-long-haul and 40/100 Gbit/s+ optical networks. This module completes PMD measurements in 4.5 seconds for any PMD value down to 0 ps, mitigating bit error rate degradation caused by high PMD in critical transmission links.

## Key Features
• Michelson interferometer architecture with broad-spectrum polarized LED source
• Operates with sources of any spectrum shape through auto- and cross-correlation knowledge
• Analyzes total link PMD through EDFA-transmitted signals
• Multiple connector options: FC/APC, FC/UPC, SC/UPC, DIN 47256, HMS-10/A, ST, E-2000
• Field-deployable design rated for extended measurement campaigns
## Typical Applications
• Long-haul optical link PMD characterization
• 40 Gbit/s and 100 Gbit/s+ transmission system qualification
• EDFA chain PMD assessment
• Ultra-long-haul fiber optic network commissioning and maintenance
## Compatibility & Integration
Designed for integration into the EXFO FTB-500 platform; also compatible with FTB-400 chassis. Pairs with light sources including FLS-110 (field deployable) and FLS-5800 (stationary lab). Commonly deployed alongside the EXFO FTB-5800 CD Analyzer module for comprehensive dispersion analysis.
