Overview
Centrally and remotely managed OTDR unit for auditing, troubleshooting and monitoring FTTx fibers.
RTU-2 - Remote test unit

Key features

  • Smaller, denser and scalable: combine modular and external switch (local or remote) to OTDR and scale up to 1024 ports per test head within 3U rack height  
  • Scalable EMS supporting over 1,000 remote test units in a single clustered instance  
  • Guaranteed HRD testing performance: 5 seconds on typical PONs with 60-cm HRD separation, using highend OTDR modules with iOLM  
  • Software architecture enabling automated and integrated workflow (e.g., iOLM, FMS, API)  
  • Most secure solution: IOT-type RTU, mutual SSL authentication  
  • Cloud-native architecture for integration in private and public clouds  

Applications

  • Versatile solution throughout network lifecycle, from build to monitor, and across network topologies (e.g., PON, P2P, distributed access)
  • End-to-end continuity and loss verification in PONs
  • Massive FTTx network auditing
  • Automated troubleshooting of fiber-related issues
  • Preventive tracking of degradations
  • Restore and repair quality assurance
