The LinkRunner 100G is the industry's smallest and lightest handheld tester for installing, verifying, and maintaining Ethernet networks from 25G to 100G. It puts the physical-layer visibility that once required a cart of modular test equipment - historically $25,000 or more - directly into the hands of the engineer holding the ticket, at a fraction of the cost.

At 25G per lane, a marginal connector can degrade a link quietly enough that switch counters still read clean, and a mismatched setting can prevent a link from establishing with no error apparent. The LinkRunner 100G is built to catch exactly that before it becomes an outage.

• Prove your network delivers the performance you're paying for.
• Validate fiber and optics before they become a 2:00 am call.
• Get evidence, not assumptions, every time you test.

  KEY FEATURES

  • Instant Network Visibility at Line Rate - In seconds, AutoTest verifies the connected switch port and its configuration, validates link speed and key network services, giving you immediate clarity and confidence.
  • Proof of Performance, Not Assumptions* - Validate true capacity and quality of transmission end-to-end, with measurable, repeatable Layer 3 performance results, so your network delivers what it promises (*requires two LinkRunner 100G units)
  • Real-World Validation of QSFP28 Optics - Test with the same optics and transceivers your production network uses, for true end-to-end verification with zero deployment surprises.
  • QSFP28 Insights - Automatically detects and validates module type, speed, FEC settings, and interface configuration across 25G, 40G, 50G, and 100G optics - single-mode, multi-mode, trunks, LC breakouts, and MTP/MPO links - so you know exactly how every module is set to operate.
  • Consolidated, Professional Reports - Automatically generates documentation that consolidates every test result - optical configuration, performance metrics, and link validation [- continue here] - into one report.
