Fluke Networks LinkRunner Duo
Network Multimeter for Fiber and Copper Cables

  • Link at 10/100/Gig – identify device capabilities and confirm actual connected speed/duplex status
  • Ping key devices – measure response statistics of DHCP, default router, DNS server, and other key devices or URLs
  • Verify 802.1X settings – authenticate on 802.1X secured networks; enter EAP type, user name, certificates, and password
  • Detect PoE service – verify availability, voltage level, and pairs of Power over Ethernet per IEEE 802.3af specifications
  • Identify port (C/E/LLDP) – identify nearest switch address, slot, and port with Cisco, Extreme, and IEEE Link Layer Discovery Protocols
  • Test cable wiremap – test wiremap and length; detect miswires, shorts, split pairs or opens; measure distance to faults with TDR
  • Locate and ID cable – use IntelliTone digital toning, hub blink feature, or optional cable IDs to locate cables at patch panels or wall jacks
  • Document test results – save link, ping, PoE, security, and cable test results in unit and upload to PC with USB cable

The Fluke Networks LinkRunner Duo is a the first speeds. That means frontline technicians now frontline tools to establish links at Gigabit speeds. That means frontline technicians now have the power to troubleshoot Gigabit link problems before they’re escalated to higher levels, giving network engineers more time to focus on optimization, planning, and expansion.

The Fluke Networks LRDUO LinkRunnerDuo not only will discover the presence of 802.1X, but can also gain authentication on 802.1X networks. The included LinkRunner Connect Software can be used to select EAP type, provide certificates, and enter passwords. Technicians can now solve 802.1X conflicts and get users back up and running fast.

The Fluke Networks LinkRunner-Duo are the first connectivity tools to support the new IEEE Link Layer Discovery Protocol (LLDP) in addition to the Cisco and Extreme Discovery Protocols (CDP and EDP). That allows technicians to speed problem resolution by precisely locating the nearest switch model, slot, and port.

When no test documentation is available, closing trouble tickets can be a frustrating and time-consuming process. Finger pointing and redundant testing are just a couple of the wastes that occur. The  Fluke Networks LinkRunner Duo eliminate these wastes by generating objective, professional test reports that can be printed or routed electronically.
