Widely used in cable construction and maintenance. Non-destructive testing of the line using macrobend technology can measure signal direction and power to avoid line interruption caused by misoperation.

● Macrobend measurement, macrobend is the use of fiber optic bending to leak a weak optical signal, by detecting the direction and intensity of the leak to detect the direction and intensity of the optical signal. Does not damage the fiber, does not interrupt communication, and can directly detect 0.25mm bare fiber, 0.9mm tight casing fiber and 2.5mm jumper.

● Audio recognition, the fiber identification device can detect the fixed audio signal loaded in the optical signal, 270Hz, 1KHz and 2KHz, to identify the specific fiber, and can quickly find the required fiber.

● Low battery monitoring function, the optical phone has its own power monitoring. When the battery is low, it will give an indication to remind the user to replace the battery to avoid interruption.
