Zoom ID-H3 Optical Fibre Identifier

ID-H3 Optical Fibre Identifier



  • Wide dynamic range
  • Super low insertion loss
  • Universal chuck
  • Bright LCD screen
  • Detects signal without traffic disruption
  • Detects tone and traffic signals
  • Direction LED signals for clear identification
  • Super lightweight industrial plastic

What's new in the FITEL ID-H/R v3?

  • Improved traffic direction recognition, even in brightly lit environments with 10 times greater sensitivity
  • Enhanced sensitivity for the light receiving adjustment function
  • The brighter LCD now displays the communication light intensity in the optical fiber
  • G657.A2 optical fiber (ITU R7.5) identification



The FITEL ID-H/R is a rugged, user-friendly tool which identifies optical fibers by detecting the optical signals passing through the fiber utilising local detection technology that detects the signal without disrupting traffic.

Includes offset function for light level with offset adjustments from 0 to 50dB in 1dB increments.
