Feature: 1. 9 Functions: The tester has 9 functions, namely OTDR, event map, optical power meter, red light source, stable light source, optical loss test, LED illumination, RJ45 line measurement, RJ45 line tracking. 2. Automatic Test and Analysis: The OTDR fibre tester can automatically test and analyse the data with a single keystroke test, without further operation. 3. Optical Power Loss Calculation: The OTDR fibre tester can be used to evaluate FTTx and access network construction and maintenance, identify fibre breaks, measure fibre lengths and calculate relative optical power loss. 4. Large Range Measurements: The OTDR fiber optic tester can measure a large range of fiber optic networks, including long haul fiber optic networks and distributed fiber optic sensing networks. 5. User Friendly Interface: Equipped with a 4.3 inch touch screen, the OTDR fiber optic tester is designed to be easy to operate. The intuitive interface provides important information at a glance, which makes the device user friendly and efficient to use.
