Fiber Optic Identifier 800–1700nm | Detect 270Hz–2kHz Signals Overview The NK430/NK432 Fiber Optic Identifier is a high-performance tool designed for non-destructive fiber identification and signal direction detection. Using advanced macrobend technology, it allows technicians to pinpoint live fibers, measure signal direction, and estimate optical power without disrupting communication or damaging the fiber. Engineered for both single-mode and multi-mode fibers, this portable identifier is ideal for field maintenance, troubleshooting, and optical network verification across telecom, data center, and FTTH environments. Key Features Non-Destructive Macrobend MeasurementDetects signal direction and intensity by analyzing the faint light leaked when a fiber is gently bent—no cutting, no interruption to live services. Supports Multiple Fiber TypesCompatible with Ф0.9mm, Ф2.0mm, and Ф3.0mm fibers (pigtails, patch cords, and jumpers). Accurate Signal IdentificationRecognizes CW, 270Hz, 1kHz, and 2kHz modulation frequencies with clear LED indicators showing left/right signal direction. Wide Detection RangeDetects optical signals from -40 to 10dBm and measures optical power ≥ -20dBm with an insertion loss ≤1dB. Built-in Lithium BatteryLong-lasting 3.7V/500mAh battery supports up to 24 hours of continuous operation; low battery alerts via yellow/red indicators. Compact and Portable DesignLightweight construction (only 79–82mm long) makes it perfect for on-site fiber inspection and quick signal tracing. Optional Bluetooth ConnectivityEnables real-time data upload and storage for enhanced testing efficiency.
