## Summary description

W-STAR WSNF8508 is a combined cable tester for RJ45 and optical fiber networks. It integrates a visual fault locator (VFL), optical power meter (OPM) and cable detector to identify breaks, loss points and cable routes. Designed for installation, troubleshooting and maintenance of structured cabling, it helps technicians quickly verify connections, locate faults and measure optical signal power.

## Long description

W-STAR WSNF8508 is a multifunctional cable tester for RJ45 and optical fiber networks that combines a visual fault locator (VFL), optical power meter (OPM) and cable detector in a single handheld unit. The tester is intended for installation, troubleshooting and maintenance of structured cabling and fiber links, enabling technicians to verify connectivity, detect breaks and identify signal loss points. Its integrated cable detector aids in locating cable routes and endpoints in patch panels and cable bundles.
Advantages
The device unifies several measurement and locating functions into one compact instrument, reducing the need to carry multiple tools. Built-in VFL provides visible red light for quick identification of breaks and poor splices in fibers, while the OPM offers objective optical power measurements to assess link performance. The cable detector function supports tone tracing and cable identification in copper RJ45 installations. The tester’s portability and combined features streamline on-site diagnostics and reduce troubleshooting time.
Suitable for
Installation and certification checks of structured copper cabling (RJ45 patch cords and terminations)
Optical fiber link verification, fault localization and splice inspection using visible light
Maintenance and troubleshooting in data centers, telecom rooms and network closets
Tracing and identifying cable routes in patch panels, wall jacks and cable bundles
Key specifications
Supported connectors: RJ45 for copper testing and standard optical fiber connectors for VFL/OPM
Visual fault locator (VFL): visible red laser/LED output for locating breaks and faults in fibers
Optical power meter (OPM): measurement range suitable for verifying transmitter/receiver levels and link attenuation
Cable detector: tone generation and detection for tracing and identifying individual copper pairs and cables
Handheld form factor: portable enclosure suitable for field use and site visits
Battery-powered operation for on-site testing without external power
How to use
Connect the appropriate interface to the cable under test — RJ45 plug for copper patch cords or the optical connector for fiber. For fiber fault localization, enable the visual fault locator and inspect the fiber path for visible red light at breaks, connectors or improper splices. Use the optical power meter to measure received optical power at the far end and compare with expected transmitter levels to calculate insertion loss. For copper lines, activate the cable detector/tone generator on the source end and use the receiver to trace the cable path and confirm pair continuity. Turn the unit on, select the required mode, and follow on-screen or labelled indicators for measurements.
Usage recommendations
Prioritize safety when using the visual fault locator: do not look directly into the VFL light source and avoid exposing others to the beam. For accurate optical power measurements, ensure connectors are clean and use appropriate reference levels. When tracing cables in bundled installations, isolate and label identified runs to prevent confusion. Store the tester in a protective case and replace batteries before long field shifts to maintain continuous operation.
