Testing fiber interfaces using SFP/SFP+ modules
Power over Ethernet (PoE) detection and delivery checks
Site acceptance and troubleshooting of network links and transmission
Key specifications
Connector support: RJ-45, SFP, SFP+
Functions: PoE detection and delivery testing, link/transmission diagnostics
Display: integrated LCD for on-device results
Battery: built-in Lithium‑Ion (3.63 V)
Certifications: EMC and FCC compliance
Form factor: handheld tester suitable for field use
How to use
Connect the LinkRunner AT 4000 to the network link under test using an RJ-45 cable for copper or insert an appropriate SFP/SFP+ module for fiber interfaces. Power up the tester using the built-in battery, select the desired test type on the display, and initiate PoE or transmission diagnostics. The tester will perform automated checks and report link status, detected PoE class and available power, and basic transmission characteristics directly on the screen. Interpret the displayed results to determine pass/fail status or to guide further troubleshooting steps.
Usage recommendations
Use the device on de-energized fiber connections when inserting or removing SFP/SFP+ modules and follow safety procedures for working near powered Ethernet equipment. For routine site validation, perform PoE and link tests at both ends of a run when possible to confirm end-to-end operability. Keep the unit charged between uses and store it in a dry, dust-free environment to preserve the battery and connectors.
