Multifunctional OTDR fiber tester is suitable for bare fiber, fiber optic patch cords, and other fibers that can leak red light, fiber optic cable near-end fault points, and high loss areas caused by micro-bending detection. OTDR fiber tester with optical time domain reflectometer/optical power meter/light source/visible light source/event map/network line test/light-up function. A fiber optic test sample is the ideal tool for fiber optic cable construction, maintenance, and monitoring.

Features

• The multi-functional OTDR fiber optic tester features a 5-inch outdoor enhanced LCD touchscreen for smooth, real-time user operation.
• Embedded ARM processor, ultra-low power consumption, and smooth operation.
• OTDR machine is mainly used to measure fiber optic cable length, loss, and splice quality parameters for fiber optic end test, fiber to the home, especially FTTH optical network testing to provide a comprehensive solution.
• The visible light (red light) is injected into the optical fiber, and the location of the optical fiber fault point can be easily and accurately determined by observing the position of light leakage on the tested fiber. Multi-functional OTDR fiber optic tester is suitable for the detection of bare fibers, fiber optic patch cords, and other fibers that can leak red light, near-end fault points of fiber optic cables, and high loss areas caused by micro-bending.
• Network line sequence measurement can detect the network line break, short circuit, or disorder, support different types of network line length measurement, and can roughly check the network line fault location point.

Tips: How to identify and deal with secondary reflection peaks on OTDR?

The spikes on the OTDR curve are sometimes due to echoes caused by closer and stronger reflections at the incident end, and such spikes are called secondary reflection peaks. The ghosting on the curve does not cause significant loss. The distance between the ghost image and the start of the curve is a multiple of the distance between the strongly reflected event and the start, in a symmetrical manner. Eliminate ghosting. Select a short pulse width and add attenuation at the front end of the strong reflection (e.g. OTDR output). If the event causing ghosting is at the end of the fiber, you can "make a small bend" to attenuate the light reflected back to the starting point.
