FORSCHER FS8117 multikabeltester voor RJ45, RJ11, BNC, USB, FireWire

When you're terminating a new patch panel in a server room or troubleshooting a dead network drop in an office, the FORSCHER FS8117 quickly identifies open circuits, shorts, and crossed pairs across RJ45, RJ11, BNC, USB, and FireWire cables. Its remote unit lets one technician test installed lines without walking back and forth, and the LED display shows each wire's status at a glance.

Key specifications

• Tests RJ45 (UTP/STP), RJ11/RJ12, BNC coaxial, USB (Type A/B), and FireWire (IEEE 1394) cables
• Detects open, short, cross, split pairs, reverse connection, shielding, and continuity faults
• LED indicators for each wire pair with fast and slow scan modes
• Powered by one 9V DC battery (not included) with low battery indicator and auto power off
• Maximum test length up to 100 meters for continuity
• Main unit and remote unit each feature RJ45, RJ11, BNC, USB Type A, USB Type B, and FireWire ports
• Durable ABS plastic housing; operating temperature 0°C to 50°C
• Includes remote unit and carrying case (may vary by retailer)

Why choose it

This tester covers the most common low-voltage cable types in one compact tool, so you don't need separate devices for Ethernet, telephone, coax, USB, or FireWire. The remote unit speeds up testing of installed cabling, and the clear LED readout removes guesswork. Auto power off preserves battery life between jobs.

Ideal use cases

• Network installers verifying Cat5e/Cat6 runs after termination
• IT technicians troubleshooting patch cords and wall outlets
• Security system installers checking BNC coaxial video cables
• AV integrators testing USB and FireWire connections
• Electricians performing continuity checks on low-voltage wiring

Good to know

The FS8117 is a straightforward, no-frills tester—it doesn't measure cable length or certify performance, but it reliably pinpoints wiring faults. Keep a spare 9V battery on hand, as it's not included. The carrying case protects the units when stored in a tool bag or van.
