Handheld Optical Fiber Identifier



* Indicate the signal directions and power in fiber

* Indicate the signal presence or absence(Live or dark fiber)

* Efficiently identifies the traffic direction and frequency tone (270Hz, 1KHz, 2KHz) with audible warning

* Displays the relative core power

* Don't need to replace adaptor

* Lower power indication

* Build in VFL function

JW3306D Optical Fiber Identifier is an important tool for optical maintenance, which is used for nondestructive fiber identification project. Meanwhile it also has Visual Fault Locator module with fault location function. Useing the macro bending technology on line for nondestructive testing, JW3306D can measure the signal direction and power and avoid misoperation resulting in interrupted lines.
