Fluke OFTM-5612B Enhanced MultiMode OTDR

The Fluke OFTM-5612B Enhanced MultiMode OTDR delivers integrated fiber optic testing, certification, and troubleshooting in a single portable instrument. Built for multimode fiber networks, it combines OTDR analysis, optical power measurement, loss/length certification, and fiber end-face inspection—eliminating the need for multiple tools on the bench or in the field. The unit identifies faults, locates events, measures link attenuation, and verifies compliance with industry standards. Auto OTDR analysis accelerates diagnostics, while LinkWare PC software manages data, performs analysis, and generates professional reports.
