The EXFO EPX500 is a high-speed optical receiver module for OC-48/STM-16 link testing at 2.488 Gbps within SONET/SDH networks. It delivers performance validation, monitoring, and compliance verification across high-speed optical infrastructures. The module installs into any gnubi chassis—including EPX16 and EPX8 platforms—and occupies a single slot. Protocol switching between SONET and SDH occurs without system power down, with selectable payload mappings for each standard.
## Technical Specifications
• Signal rates: SONET OC-48 (2.488 GHz), SDH STM-16
• Optical interface: SC/PC connector
• Input power range: −28 dBm to −9 dBm
• Monitoring rate: 2.488 GHz
• Operating temperature: 0°C to 40°C (non-condensing)
• Chassis expandability: Up to 17 modules per chassis for multi-port testing
## Key Features
• Full-featured SONET/SDH payload monitoring and overhead capture
• SONET alarm and error monitoring with counts and ratios
• Live traffic analysis and performance statistics
• Service disruption measurement (switch times for network elements and optical switches)
• SONET trace message monitoring
• Pointer event count and K1/K2 byte value monitoring
• PRBS (Pseudo-Random Binary Sequence) data pattern support
• Remote operation via web browser or EPXam GUI tools (Group Manager, Test Controls, Script Runner)
• Test configuration save/restore and logging
• Scripting support for test sequence automation
• Cross-user resource sharing
• Checkpoint/resume functionality for setup and test data recovery
## Typical Applications
• OC-48/STM-16 link performance validation
• SONET/SDH network compliance verification
• Optical infrastructure monitoring and troubleshooting
• Multi-port simultaneous testing
## Compatibility & Integration
Compatible with all gnubi chassis models (EPX16, EPX8, and others). Operates as a plug-in module requiring one chassis slot. Supports both SONET and SDH protocols with protocol switching capability without system restart.
