Feature: 1. FIBER OPTIC TESTER: This intelligent optical time domain reflectometer offers diverse functions such as fiber optic communication measurement, network cable sequencing, optical power meter, stable light source, VFL, and RJ11 wire tracing. 2. ACCURATE FAULT LOCATION: OTDR accurately identifies the location of fiber optic faults, detects faults in bare fibers, jumpers, and other light emitting fibers or cables near the fault point, as well as high loss sections caused by micro bends. 3. ACCURACY SIGNAL TESTING: The high performance optical power meter is ideal for signal power testing and insertion loss testing of various equipment and optoelectronic components. 4. CLEAR OTDR INTERFACE: The tester provides a clear interface for OTDR testing, displaying comprehensive information such as fiber loss distribution curves, fiber distance, loss, and attenuation, allowing for easy analysis and troubleshooting. 5. EASY CARRYING: Comes with a compact size and a light weight as well, the OTDR is very convenient to carry for both indoor and outdoor use.
