Your complete guide to cable colour codes
Standardised colour codes are the foundation of telecommunications and data cabling. They allow technicians to identify, terminate and trace any conductor in a multi-pair cable, from a single twisted pair through to 600-pair backbone runs. A proper understanding of the colour code system is essential for clean terminations, accurate troubleshooting and compliance with Australian cabling standards.
Our reference guides cover the colour code system from the underlying tip and ring logic through to pinouts on common data plugs and sockets. Use them as a quick on-site reference or as a training resource for new installers.
