 What is a CAT 6A jack? The majority of CAT 5E and CAT 6 cabling terminations are completed with what is referred to as a module. A termination module is a one-piece unit that contains the RJ termination outlets and a plastic casing that fits directly into a faceplate. At the patch panel end, all 24 terminations are pre-built into the panel. With CAT 6A cable terminations, a termination jack is used. This is a square termination block where the cable is connected. This is the same for both the user outlet and patch panel end. These jacks are then snapped into suitable shutters that fit a faceplate or floor box. Furthermore, the patch panels have 24 empty slots of each which these jacks snap into. The termination jack allows the cable to be terminated in a straight line and allows the termination standards and bend radius to be maintained. This couldn't be achieved with standard modules.
