SKU CH-R830-7P3V8

Validates twisted-pair cables up to 10 Gig and provides switch, VLAN and PoE diagnostics for installation and troubleshooting

  • Validates twisted-pair cables up to 10 Gig performance
  • Identifies switch name, port and VLAN for fast troubleshooting
  • Runs PoE load tests to verify power delivery
  • Graphical wiremap reveals opens, shorts, miswires and split pairs
  • Supports industrial Ethernet protocols with M8D, M12D and M12X connectors

What the LinkIQ LIQ-100 tests

The Fluke Networks LIQ-100 LinkIQ Cable and Network Tester validates twisted-pair cable performance up to 10 Gig using frequency-based measurements. It provides connected switch information including name, port and VLAN for rapid diagnostics. Built-in PoE negotiation and load testing supports installation and troubleshooting of powered devices. A graphical wiremap detects opens, shorts, miswires and split pairs in a single view.

What to verify before ordering

Confirm the cables you test use twisted-pair construction compatible with the supported industrial connectors such as M8D, M12D and M12X. Ensure the network environment allows 802.1x authentication if you plan to use that feature for switch access. The tester includes analog and digital toning plus port blink for cable tracing, so check whether those functions match your tracing workflow. LinkWare PC reporting software is available for documentation and analysis.

Thermals noise and power in use

The handheld instrument runs on internal batteries during field work, so no external power supply is required for typical cable and network tests. Operation is silent with no moving parts, making it suitable for quiet office or data-centre environments. Heat output is negligible during normal measurement cycles, allowing extended use without thermal concerns. Battery life supports a full day of continuous testing across multiple sites.

Questions about this item

Does the LinkIQ LIQ-100 ship with the remote identifiers needed for cable mapping or must they be purchased separately?

The LIQ-100 includes twelve remote identifiers in the box so cable mapping and length measurements work immediately without extra purchases.

Should I choose the LIQ-100 over a lower-tier model if I only need 1 Gig validation today but may need 10 Gig later?

The LIQ-100 validates twisted-pair cabling up to 10 Gig, so it covers both current 1 Gig links and future 10 Gig upgrades in a single instrument.

What does the 10 Gig rating mean when I connect the tester to a live switch port?

It means the LinkIQ measures cable performance to 10 Gig frequencies, reports the connected switch name, port, VLAN and negotiates PoE load up to 802.1 standards.
