The Fluke Networks DTX-MFM Multimode Fiber Module expands DTX CableAnalyzer Series capabilities for certifying multimode fiber optic cabling systems. It measures optical loss, length, and propagation delay on multimode fiber links while ensuring compliance with ISO and TIA standards. The module accelerates certification workflows, allowing technicians to test and document multimode fiber installations efficiently through integration with LinkWare™ PC software.
