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.
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.
