Live Optical Fiber Identifier with wave respond 800-1700nm Built in 10KM VFL and Optical Power Meter OPM Functions FTTH Tool (YD-3309D-Y)

"YD-3309D is latest Optical Fiber Identifier ,is 3 in 1 functions.

Optical Fiber Identifier is an important tool for optical maintenance,which is used for non-destructive fiber identification 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 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."
