The FI-3A Optical Fiber Identifier is a low cost and handheld device designed to detect optical signals in live fibers. It is used during maintenance, installations, rerouting or restoration when isolating a specific fiber is necessary. By simply clamping the FI-3A onto a fiber, any existence of signal or traffic and signal direction can be detected.
FEATURES
- "One-button meter", convenient and easy to use
- Non-destructive macro-bend detection method
- Availability of adapters for different bare fibers and jacketed fibers
- Detect a variety of optical frequency : 270Hz, 1kHz and 2kHz
- Traffic direction detection
- LED indicator of Optical Signal Intensity
- Powered by 2 units of 1.5V AA alkaline batteries
