FV-74205E 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-74205E 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 the signal direction and frequency (270Hz, 1KHz, 2KHz) with audible warning

Displays the relative core power

No need to replace adaptor

Lower power indication

Build in VFL function

Build in OPM function
