Cable testing you trust. Network testing you need.

LinkIQ™ enables you to:

  • Find maximum cabling speed (Up to 10 Gb/s). Ethernet Alliance Certified for reliable multivendor interoperability
  • Install and troubleshoot PoE devices via Switch Negotiation and PoE Load Test
  • Discover connected switch information (Switch Name, IP address, Port Number, MAC Address, and VLAN)
  • Test connectivity to TCP/IP network through IP configuration and ping
  • Verify Gateway and DNS server responsiveness and availability
  • Document your work through LinkWare™ PC


The LinkIQ™ Cable+Network Tester is the testing solution to verify cable performance up to 10 Gb/s and solve network connectivity problems. LinkIQ validates cable performance using frequency-based measurements and a wire map of the cable under test. The LinkIQ also performs ping tests to verify connectivity and nearest switch diagnostics to identify key network issues and validate switch configuration - eliminating the need for another device. Additional features include Analog and Digital Toning, Port Blink, Remote Office Locators, and the ability to manage results via LinkWare™ PC.

Cable Testing You Trust

The LinkIQ™ is capable of measuring lengths up to 1000 feet (305 m) and provides distance to faults such as opens, shorts, and unterminated cable. Using the remote ID allows for a complete wire map of the cable pairs which helps identify miswired and split pairs. The primary cable testing feature of LinkIQ™ is the cable performance test which qualifies the cabling bandwidth from 10BASE-T to 10GBASE-T (10 Mb/s up to 10 Gb/s). It performs these tests via frequency-based measurements. Using IEEE-standards-based measurements ensures that tested links meet performance requirements as opposed to transmission testers which only prove that the specific test devices can communicate over the link.

Operators may set performance requirements from 10 Mb/s to 10 Gb/s for a simple pass/fail indication.

Cable test with remote attached shows remote ID number 1

Cable test with remote attached shows remote ID number 1, length and pairing of each wire and cable performance of up to 2.5 Gb/s but failed the test due to a user-set limit of 10 Gb/s performance.

Network Testing You Need

Along with the robust cable testing features, the LinkIQ™ also provides detailed information on the nearest connected switch and connectivity testing with IP ping. The LinkIQ™ negotiates with the switch to identify the advertised  data rate (up to 10GBASE-T), half/full duplex identification, the switch name and IP address, port number, and VLAN info.



Switch port test shows port number, switch name and port VLAN along with advertised speed and duplex settings

Switch port test shows switch name and IP address, connected port, and VLAN along with advertised speed and duplex settings. If a ping test is configured, the target address and average response time are shown.  Scrolling down shows Power over Ethernet results.

The ping test verifies connectivity to devices on the local network or the internet and supports both IPv4 and v6.  The LinkIQ’s address may be set up manually or through DHCP. Once set up, the ping test is run as part of the Autotest when a switch is detected.  Results of the ping test include identification and response time of each of four pings to the target, the DNS server and gateway.

Ping result screen shows response time to target for each of four pings. Scrolling down displays DHCP, DNS and gateway information.


In-Depth PoE Testing

While Power over Ethernet makes installation of devices such as security cameras and access points simpler, a survey by the Ethernet Alliance of over 800 installers, integrators and end users found that four of five respondents experienced difficulties in integrating PoE systems. Part of this can be traced to the fact that the IEEE offers three PoE standards, the term “PoE” is not registered and there are a variety of non-standards-compliant implementations as well.

Switch port Power over Ethernet result shows pairs used, power and class available and results of the PoE test under load.

To simplify PoE installation and troubleshooting, the LinkIQ displays the pairs where power is provided, including the different power levels and pairs for dual-signature implementations. Further, the LinkIQ will actually place a load on the connection to ensure that the advertised power is actually being delivered by the switch across the cabling infrastructure. The LinkIQ has been certified by the Ethernet Alliance to IEEE-802.3™ standards for reliable multivendor interoperability.

LinkWare™ Documentation

The LinkIQ provides complete documentation abilities for the tests it performs. Up to 1,000 results can be stored in the tester with descriptive names and recalled. Test names and numbers automatically increment as each is saved (“Annex B-1”, “Annex B-2”, “Annex B-3”, etc.) saving lots of time when testing cables in sequence.

Report data may be exported to a PC for documentation purposes. The LinkIQ uses LinkWare™ PC, Fluke Networks’ reporting software which supports a variety of testers going back 20 years and is the industry’s de facto reporting solution with tens of thousands of active users. LinkWare can be used to store the results as well as generate PDF reports.
