Fluke Networks LIQ-100 LinkIQ Cable + Network Tester, Gray

Diagnosing network cable faults and validating switch port performance without the right tool can cost you hours of frustrating guesswork. The Fluke Networks LIQ-100 LinkIQ cable and network tester is the Essential solution for IT professionals and installers who need accurate, fast results without carrying a bulky, expensive analyzer. Whether you are troubleshooting a dead port or verifying a new cable run, this compact tester delivers the clarity you need on the spot.

What sets the Fluke Networks LIQ-100 LinkIQ cable tester apart from basic continuity checkers is its ability to identify the switch port a cable is connected to, display the negotiated link speed, and measure cable length using time-domain reflectometry (TDR) technology. It tests Cat 5e, Cat 6, Cat 6A, and Cat 7 copper cabling, so it covers virtually every installation you will encounter in a modern office or data center environment. The unit measures approximately 5.5 x 2.6 x 1.2 inches and weighs under 6 ounces, making it easy to carry in a tool bag or shirt pocket.

• Instant switch port identification saves you from manually tracing cables through crowded patch panels, displaying the switch name and port number directly on screen.
• Accurate cable length measurement using built-in TDR technology lets you confirm runs are within spec before a client ever complains about performance issues.
• Negotiated speed reporting tells you exactly what speed a switch port has agreed to, helping you catch mismatched duplex and speed settings immediately.
• Wide cable compatibility across Cat 5e through Cat 7 copper means you can use one tester across virtually every project without purchasing additional adapters.
• Rechargeable battery design with USB-C charging eliminates the inconvenience of hunting for replacement batteries in the middle of a job.
• Rugged, field-ready construction in a compact gray housing holds up to daily professional use without adding bulk to your kit.

The Fluke Networks LIQ-100 LinkIQ cable and network tester is best suited for network technicians, structured cabling installers, and IT support staff who regularly validate or troubleshoot copper Ethernet installations. If you are an occasional home user dealing with a single problem port, a simpler tester may serve your needs, but for anyone doing this work professionally or semi-regularly, the LIQ-100 pays for itself quickly in time saved. It pairs particularly well with a quality punch-down tool and cable stripper to round out an efficient troubleshooting kit.
