The EXFO FTB-5503 PMD Analyzer Module is a plug-in unit for the EXFO FTB-400 Universal Test Platform, engineered to characterize Polarization Mode Dispersion (PMD) in optical fibers at 1550 nm. PMD measurement is critical for maintaining signal integrity and performance in long-haul and high-bit-rate optical networks.
## Technical Specifications
**PMD Measurement Performance**
• Measurement Principle: Interferometric method, offering immunity to vibrations and adverse field conditions
• Analysis Range (Standard): 0.05 ps to 35 ps at 1550 nm
• Analysis Range (Extended with ER option): 0.05 ps to 200 ps at 1550 nm
• Calculated values can achieve lower than 0.05 ps; estimated values extend to 200 ps with extended range
• Dynamic Range: 42 dB (56 dB with M2100 Light Source); reduced when PMD exceeds 5 ps
• With M2100 Broadband Light Source and high dynamic range option: > 55 dB for spans exceeding 250 km
• Measuring Time: 15 seconds for PMD < 1.2 ps at 1550 nm
• Accuracy: 2σ = 0.17 × (PMD/N) + 0.052 ps over N measurements at different polarization states
• Repeatability: 1 % ± 0.052 ps without change in measurement conditions
• Second-Order PMD: Software calculates second-order PMD delay, coefficient values, and PMD coefficient as a function of link length
• Auto-Range Function: Automatically scans and selects optimal measurement range for unknown PMD values
**Operating Environment**
• Operating Temperature: 0 °C to 40 °C (32 °F to 104 °F)
• Storage Temperature: –20 °C to 50 °C (–4 °F to 122 °F)
• Relative Humidity: 0 % to 80 % non-condensing
