Optical Fiber Identifer is an important tool for optical maintenance,which is used for nonderstructive fiber identificaton project.Meanwhile it also has Visual Fail Locator module with fault location function and power meter function. Using the macro bending technology on line for nondestructive testing.it can measure the signal direction and power and avoid mis-operation resulting in interrupted lines. ----Macro bending measurement .Macro bends are the use of fiber-optic bending leak out when the weak optical signal,optical signal to detect the direction and intensity.Does not damage opticla fiber,without interrupting communications,and durection of 2.5mm bare fiber,0.9mm and 2.5mm fiber casing tight jumper. Feature: 1.Build in 10 KM VFL function.2. Build in OPM3. Metal gripper,no need to change the adapter.4. Low battery moniting function.5. Tone identification,optical fiber identifier can detect optical signals in the tone signal fixed load,270Hz,1KHz and 2KHz,to identify a specific optical fiber,can quickly find the necessary fiber.
