The LinkRunner AT 4000 is an advanced cable and network tester for Multigigabit NBASE-T and fiber Ethernet networks, including comprehensive network discovery and topology mapping with advanced diagnostics and problem detection for in-depth troubleshooting.
Using network discovery and layer 2 and 3 path analysis, the LinkRunner AT 4000 offers comprehensive network visibility to help resolve issues impacting multiple devices – not just a single link – while still providing the automated tests for moves/adds/changes validation and troubleshooting that the LinkRunner AT family of test solutions is known for.
Test results can be automatically uploaded to the Link-Live collaboration, reporting, and analysis platform to improve teamwork between network engineers and technicians, creating greater job visibility, better project control, and improved tester fleet management. Independent management plane via wired or Wi-Fi connection (with optional adapters) allows remote operation and result uploading separate from the network under test.

The LinkRunner 10G is a high-performance portable Ethernet tester for Mult-Gig and 10 Gig networks (copper and fiber) that simplifies validation and configuration and streamlines workflows by combining essential functions into a single, portable, ruggedized unit.
Install, test, verify, and troubleshoot technology upgrades, Multi-Gig (NBASE-T), and 10G networks with purpose-built hardware at line-rate.
Physical layer testing includes cable (TDR) testing, toning, and wire mapping.
Supports LANBERT™ Media Qualification testing to quickly validate if your existing cable plant can support higher speeds.
Compatibility with standards-compliant SFPs enables test and validation of any wired media (copper or fiber).
Validate up to 90W 802.3bt PSE with TruePower™ loaded Power over Ethernet (PoE) test.
As a light-weight, handheld, mutli-function instrument, LinkRunner 10G is perfect for remote site validation and troubleshooting, eliminating the need to purchase multiple testers, and the need to carry a fragile laptop PC or tablet. Advanced apps make the user's workflow more efficient, by expanding the usage of the instrument beyond testing, allowing the user to check trouble tickets, run speed tests, configure network devices and complete other tasks with it's smartphone-like features.
Kit Includes: LR10G-200-KIT Linkrunner Ethernet Tester, One year of AllyCare support (LR10G-200-1YS), AC Charger (G3-PWRADAPTER), EXG-LR10G-HOLSTER, SFP+ Optical Transceiver Module, multimode (SFP+MR-10G850), SFP+ Optical Transceiver Module, singlemode (SFP+MR-10G1310), RJ-45 inline coupler, WIREVIEW wire mapper #1-6, Quick Start Guide, Medium soft case
Features
Layer 1-7 AutoTest helps technicians find network problems, while the periodic test mode monitors networks for intermittent issues, every minute for up to 24 hours.
Two LinkRunner 10G units can be used to test network performance, capacity, QoS, and service provider SLAs between sites.
Automatically discover devices in your network and generate topology maps* using Link-Live; identifies changes, uncovers security threats, and helps you keep documentation up-to-date.
Line-rate capture up to 10Gbps ensures no packets are lost.


The LinkRunner AT 3000 is designed for frontline technicians who need fast and comprehensive validation of copper and fiber network links with powerful network connectivity troubleshooting. While offering the same core functions of its predecessors (LinkRunner AT 1000 and 2000 models), the LinkRunner AT 3000 features a large touchscreen and in-depth AutoTest that provides deeper network visibility.
With tools designed to help with network changes and troubleshooting, this network tester’s quick cable test and switch identification functionality facilitates installation validation and fast problem isolation.
Test results can be automatically uploaded to the Link-Live collaboration, reporting, and analysis platform to improve teamwork between network engineers and technicians, creating greater job visibility, better project control, and improved tester fleet management. Independent management plane via wired or Wi-Fi connection (with optional adapter) allows remote operation and result uploading independent of the network under test.
Key Features
Comprehensive AutoTest validates and troubleshoots all aspects of network link connectivity and services including DHCP and DNS.
Verifies link speed/duplex for 10/100 Mbps and 1 Gbps, with detection of NBASE-T and Multigigabit 2.5G, 5G, and 10 Gbps links.
Discovers nearest connected switch name and port information via CDP/LLDP/EDP, including VLANs; monitors VLAN trunk traffic.
Validates Power over Ethernet switching and cabling up to 90W 802.3bt with TruePower™ loading.
Advanced twisted-pair cable tests for length, wiremap, and faults such as shorts, opens, mis-wires (split pairs, crossovers), fiber optic link signal strength power measurement and SFP diagnostics. Locate cable endpoints with optional WireView adapters and analog or digital tone generators.
Use optional USB Wi-Fi/Bluetooth adapter for connectivity and remote control. 1
