Comprehensive Testing:Supports RJ45 (CAT5/5e/6/6A/7) and RJ11 telephone cables. Quickly identifies continuity, shorts, opens, miswiring, and shielding status for LAN and phone line troubleshooting.

Smart & Adjustable:Features one-button operation with fast/slow scan modes. Dual LED indicators on the master and remote units display each wire's connection order clearly, making error detection effortless.

Shielded Cable Detection:The built-in "G" light instantly indicates whether you are using shielded (FTP/STP) or unshielded (UTP) cables, ensuring accurate diagnostics for complex installations.

Detachable Remote Unit:The split-type design allows testing of both ends of long cable runs simultaneously. Perfect for wall-mounted outlets, structured cabling, and long-span network setups.

PoE & Safe Operation:Supports PoE power supply situations up to 60V max (typical telephone lines 48-72V). Compact, lightweight, and crafted from durable ABS plastic for reliable on-the-go field use.

Package Includes:
1 x Network Cable Tester (Master & Remote)
1 x User Manual

Description:
This all-in-one network cable tester is an essential tool for IT professionals, network engineers, electricians, and DIY enthusiasts. Designed to save time on LAN and phone line troubleshooting, it accurately tests RJ45 Ethernet cables (CAT5/5e/6/6A/7) and RJ11 telephone lines (6P2C/4P4C/6P6C).

The tester features an adjustable fast/slow scan mode, allowing you to fine-tune testing for precise results. The split remote unit enables simultaneous testing of both cable ends, making it ideal for long-distance runs and wall outlets. High-visibility LED indicators on both units show the wire mapping order, while the dedicated "G" light confirms shielded (STP/FTP) or unshielded (UTP) cable status.

Crafted from durable ABS plastic, this pocket-sized tool is rugged enough for daily fieldwork. The package includes everything you need to maintain and troubleshoot your network infrastructure.
