Fg-630-otdr – Essential professional-grade optical time-domain reflectometer (OTDR) for fiber optic cable installation, testing, and troubleshooting. This advanced instrument measures and visualizes fiber optic cable performance by injecting laser pulses and analyzing reflected light to detect faults, measure loss events, and characterize fiber quality. Provides high dynamic range (40dB+) for testing diverse fiber types including single-mode, multimode, and PON fibers across multiple wavelengths (1310nm, 1550nm, 1625nm). Precision measurement capabilities detect cable breaks, bad connectors, excessive bends, splice losses, and other signal degradation events with distance accuracy to ±0.1m. Real-time display shows waveforms, event analysis, and fiber characteristics on large color touchscreen interface. Automated testing configurations streamline setup for common network types. Dual-ended bidirectional testing capability improves measurement accuracy per IEC and ITU-T standards. Data storage supports 50,000+ measurement traces with expandable microSD card support. USB and Ethernet connectivity enable remote monitoring and data transfer. Portable rechargeable batteries ensure field deployment flexibility. Compliance with fiber testing standards required for Tier 2 certification testing. Ideal for network installation verification, performance baseline documentation, and rapid fault location to minimize service downtime.
