The EXFO PPM-352B-EG-EA-VZ1 is a dual-port pass-through power meter engineered for PON network testing and characterization. It delivers simultaneous filtered measurement and display of all signals across BPON, EPON, and GPON architectures at 1310 nm (upstream), 1490 nm (downstream data/voice), and 1550 nm (downstream video). The pass-through configuration maintains full OLT-to-ONT communication during measurement, allowing the ONT to remain operational throughout testing. This capability is critical for validating network performance without service interruption.
## Technical Specifications
• **Network Compatibility:** BPON, EPON, GPON
• **Wavelengths Measured:** 1310 nm (upstream), 1490 nm (downstream), 1550 nm (downstream)
• **Measurement Type:** Simultaneous display of all PON signals including voice, data, and video
• **Signal Processing:** Filtered measurements with distinct power values per wavelength; handles continuous signals (video at 1550 nm) and framed signals (ATM, Ethernet); capable of measuring power during keep-alive transmissions and burst signals with short timeslots
• **Configuration:** Two-port pass-through topology
• **Measurement Range:** Standard range plus extended-range (ER) option for central office and pre-splitter testing
• **Thresholds:** Pass/warning/fail indicators with up to 10 user-definable threshold sets; each set includes discrete pass/warning/fail values for 1310 nm, 1490 nm, and 1550 nm; configurable by location (CO, FDH, drop terminal, ONT) via PC-based software transfer
## Key Features
• Simultaneous multi-wavelength power measurement without service disruption
• Threshold-based automated assessment with location-specific configuration
