What is a Cable tester?

A cable tester is a device used to measure the performance and connectivity of electrical and communication cables. It is employed to identify issues such as open circuits, short circuits, crosstalk, and signal loss. Specific models cater to various types of cables, including LAN cables, fiber optic cables, and USB cables. Cable testers play a critical role in factory production lines and on-site communication infrastructure installations. Some devices also feature functions like cable length measurement and fault location identification. With simple operation, they enable quick and accurate measurements, making them indispensable tools for troubleshooting and routine maintenance.

Application of Cable tester

✅Connection Testing of LAN Cables
Quickly identifies open circuits or miswiring in LAN cables during corporate network installations.
✅Loss Measurement of Fiber Optic Cables
Ensures proper connections by measuring signal loss and reflectance in optical communication infrastructure.
✅Conductivity Testing of USB Cables
Verifies conductivity and pin connections of USB cables in electronics manufacturing environments to ensure quality.
✅Quality Control in Cable Manufacturing Lines
Automatically detects defective cables in mass production to confirm compliance with quality standards.
