D YEDEMC Live Optical Fiber Identifier with Wave Respond 800-1700nm Built in 10mw VFL FTTH Tool
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.
This Optical Fiber Identifer is an important tool for optical maintenance,which is used for nonderstructive fiber identificaton project.Meanwhile it also has Visual Fault Locator module with fault location function.Useing the macro bending technology on line for nonderstructive testing.it can measure the signal direction and power and avoid misoperation 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 25mm bare fiber,0.9mm and 2.5mm fiber casing tight jumper.
----Tone identification,Optical Fiber Identifier can detect optical signals in the tone signal a ficed load,270Hz,1KHZ and 2KHz,to identify a specific optical fiber,can quickly find the necessary fiber.
----Built-in VFL function.The output power of it is 10mW.---Low battery monitoring function,when battery power is insufficient to issue instructions to remind users to change batteries.
Note: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.
