Overview

The Fluke Networks LinkIQ™ Duo is a comprehensive, all-in-one testing solution designed for network engineers and technicians to verify cabling performance and resolve connectivity issues. By utilizing frequency-based measurements, it qualifies cable bandwidth up to 10 Gb/s and provides detailed wire map analysis to ensure compliance with IEEE standards.

Engineered for versatility, the device eliminates the need for multiple tools by combining cable performance verification with network diagnostics. It performs ping tests for both IPv4 and v6 connectivity, identifies nearest switch details including port and VLAN information, and executes load tests to verify Power over Ethernet (PoE) performance up to Class 8.

The Duo model specifically adds advanced Wi-Fi analysis capabilities, supporting up to Wi-Fi 6E. It provides insight into networks, channels, and access points, while identifying common configuration issues such as channel overlap or weak security. The unit is housed in a rugged, handheld design with a color touch-sensitive display, making it suitable for both field and telecommunications room environments.

Key Features

• 10GBASE-T Qualification
  Verifies cable performance and bandwidth up to 10 Gb/s using frequency-based measurements to ensure data speed requirements are met.
• Wi-Fi 6E Analysis
  Analyzes 2.4 GHz, 5 GHz, and 6 GHz bands to report network availability, signal strength, and security types.
• PoE Load Testing
  Performs a hardware-based load test to ensure the switch can actually deliver advertised power (up to Class 8) to connected devices.
• Switch Diagnostics
  Retrieves switch name, IP address, port number, and VLAN information via LLDP/CDP protocols for rapid troubleshooting.
• Wire Map & TDR
  Identifies distance to faults, including opens, shorts, and split pairs, with a maximum length measurement of 305 meters.
• Ping Connectivity
  Verifies network connectivity by performing IPv4 and v6 ping tests to targets, DNS servers, and gateways.
• Toning Functionality
  Generates both digital and analog tones, compatible with IntelliTone™ and Pro3000™ probes, to simplify cable tracing.
• Result Management
  Saves up to 1,000 test results internally for export to LinkWare™ PC for professional reporting.
