Unit is Perfect Condition as Pictured

 Fluke DTX-OTDR tests Singlemode (1310,1550) and Multimode(850,1300) w/ Visual Fault Locator (VFL)




DTX Compact OTDR Module.
• Turn your cable tester into an OTDR
• Test and troubleshoot fiber like an expert with easy-to-use DTX Compact OTDR
• Shoot OTDR traces on singlemode and multimode links at 850 nm, 1300 nm, 1310 nm, 1550 nm
• Perform extended Tier 2 certification with one powerful cable tester

Fluke Networks Compact OTDR module is the latest enhancement to the DTX CableAnalyzer. In
addition to performing copper certification and diagnostics, your team can become fiber test
experts when you decide to grow your business and turn your cable tester into an OTDR. This full
featured, compact OTDR module snaps onto a DTX CableAnalyzer and provides unmatched ease of
use for premises fiber testing and can be installed on a your own DTX CableAnalyzer.
