Secure RJ copper system is designed to enable port protection in standard RJ-45 copper ports in data center, telecommunication room and work area applications. The system consists of locking patch cords, trunks and port blockers. Secure RJ patch cords and trunks prevent unauthorized and unintentional port access to ensure continuous connectivity of high priority ports. Port blockers prevent unauthorized port access and reserve the port that is designated for a future priority service. All components are available in eight unique colours to identify, reserve and segregate network ports. Each colour requires its own colour-matched extraction tool to unlock a secured port.
