## Summary description

W-STAR WSNF859GT is an RJ45 cable tester with 10-in-1 functionality designed to diagnose network cabling. It supports RJ45 connectivity and includes PoE testing and VFL (visual fault locator) features to detect breaks, shorts, miswires and signal presence. Suitable for installers and technicians for rapid verification and troubleshooting of Ethernet links.

## Long description

The W-STAR WSNF859GT is an RJ45 cable tester offering 10-in-1 diagnostic functions for Ethernet cabling. Designed for installers and network technicians, this compact tester checks continuity, detects opens, shorts and miswires, verifies signal presence on twisted-pair lines and provides Power over Ethernet (PoE) testing. An integrated visual fault locator (VFL) assists in locating breaks and faults along fiber-like or cabling runs where visual indication is helpful. The device is intended for rapid verification and troubleshooting of network links during installation, maintenance and repair work.
Advantages
The tester consolidates multiple diagnostic functions into a single handheld unit, enabling faster on-site fault isolation without carrying several instruments. Built-in PoE testing identifies power delivery on Ethernet lines and helps verify compatibility with powered devices. The visual fault locator feature provides an additional method to pinpoint discontinuities or damage along cable runs. The tester’s RJ45 focus makes it suitable for twisted-pair Ethernet environments and routine network verification tasks.
Suitable for
Installation and commissioning of Ethernet cabling
Field troubleshooting of network links and patch panels
Verification of PoE presence and basic power checks
Locating breaks and faults in cabling runs using VFL
Key specifications
Connector type: RJ45 (8P8C) for twisted-pair Ethernet
Functionality: 10-in-1 cable diagnostics including continuity, open, short and miswire detection
PoE testing: detects presence of power on Ethernet pairs
Visual fault locator (VFL): visual indication to assist in locating breaks and faults
Form factor: handheld, portable unit suitable for field use
How to use
Connect the RJ45 plug of the tester to the network cable or patch panel port to be tested. Select the appropriate test mode on the device to run continuity, pair mapping or PoE detection routines. Observe the tester’s indicators to determine if there are opens, shorts or miswires and whether PoE is present. Use the VFL mode where available to generate a visual indication along the cable run to help locate a physical break or fault. Follow standard safety practices when testing live network links carrying power.
Usage recommendations
Use the tester for preliminary diagnostics and verification; follow up with full certification tools where link performance metrics such as throughput and attenuation must meet specific standards. Avoid using VFL on active optical transceivers and ensure that live power is considered when performing PoE checks.
