The FITEL ID-H/R V3 is an advanced and compact tool to identify the optical signals passing through the fibre.

The version 3 unit offers enhanced fibre detection to facilitate working in brightly lit environments. Improved display functionality to show the communication light intensity in the optical fibre. The unit is also now compatible will all G657 A2 Fibers.
