Indicate the signal directions and power in fiber,displays the relative core power.(Macro bends are the use of fiber-optic bending leak out when the weak optical signal).Some fiber cladding is too thick, or some light is not easy to leak out (for example 850/1300nm), so it's hard to measure. The easiest to measure wavelength is 1310 / 1550nm.If you want to measure accurate power, please choose a power meter. Indicate the signal presence or absence(Live or dark fiber) Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning Build in VFL 10mw red light source can measure the distance is about 10-15 kilometers.
