Vention KEFB0 Network Cable Tester RJ45 RJ11

Vention KEFB0 Tester

The Vention Network Cable Tester provides essential diagnostic capabilities for verifying the integrity of twisted pair Ethernet and telephone cabling. This hardware tool supports RJ45 and RJ11 interfaces. It allows technicians to identify miswires, short circuits, and open circuits across Cat5e, Cat6, and Cat6a installations. The device utilizes a split-unit architecture. It comprises a master and a remote unit. This design facilitates testing across patch panels or between wall outlets and equipment rooms. Consequently, network engineers can validate end-to-end connectivity without moving large equipment. The tester uses an automated scanning process. It cycles through each pin to confirm 1-to-1 mapping. Therefore, it is a critical asset for infrastructure maintenance and new deployments.

Key Features

• Dual Interface Support
  The unit features dedicated ports for 8P8C RJ45 Ethernet connectors and 6P4C/6P2C RJ11 telephone connectors.

• Diagnostic LED Array

  • Nine LED indicators display the status of each individual wire.
  • The ‘G’ indicator specifically validates the integrity of shielded (STP) cable grounding.
  • Sequential lighting patterns identify crossover or straight-through configurations.

• Adjustable Testing Speed
