In-service OTDR for CWDM/DWDM networks—1310/1550/1625/1650 nm options, automated fault localization, scheduled tests, and NMS/Web/CLI/Netconf integration.
The OTDR Card enables precise, remote fiber diagnostics without truck rolls. Designed for HYD 1U/2U/5U platforms, it injects test pulses at maintenance wavelengths (e.g., 1625/1650 nm with filters) to localize breaks, macro-bends, high-loss splices, or dirty connectors—while leaving traffic at 1310/1550 nm undisturbed.
Automatic event detection, distance-to-fault, and attenuation profiling speed troubleshooting and commissioning. Technicians can schedule periodic traces, compare baselines, and receive alarms when drift exceeds thresholds. Results are stored locally and exportable for reports. The card interoperates with OLP, OCM/OLPM, and EDFA/Raman modules for closed-loop maintenance and faster MTTR.
