FV-74204D 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. Using the macro bending technology online for nondestructive  testing, FV-74204D can measure the signal direction and power and avoid mis-operation  resulting in interrupted lines.

Indicate the signal directions and power in fiber

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

Identify signal 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
