How to Terminate CAT6A Shielded RJ45 Connectors

To terminate CAT6A shielded RJ45 connectors, you need to strip the outer jacket, separate the twisted pairs whilst maintaining their twist, connect the drain wire to the connector's shield, arrange wires according to T568A or T568B standards, and crimp using a quality RJ45 crimping tool designed for shielded connectors. The shielding must be properly grounded through the drain wire to maintain electromagnetic interference (EMI) protection and achieve 10 Gigabit performance.

Step-by-Step CAT6A Shielded RJ45 Termination Process

Tools and Materials Required

• CAT6A shielded cable
• Shielded RJ45 connectors
• Cable stripper or sharp knife
• RJ45 crimping tool
• Cable tester
• Wire cutters

Termination Steps

Step 1: Strip the Outer Jacket
Remove approximately 25mm of the outer jacket using a cable stripper. Be careful not to damage the internal shielding or twisted pairs.

Step 2: Handle the Shielding
CAT6A shielded cables typically have an aluminium foil shield and a drain wire. Fold back the foil shield and locate the bare drain wire, which provides the ground connection for the shield.

Step 3: Untwist Wire Pairs
Carefully untwist the four pairs, maintaining as much twist as possible until the last moment. CAT6A requires minimal untwisting to maintain performance specifications.

Step 4: Arrange Wires
Arrange the eight wires according to either T568A or T568B wiring standard. T568B is more commonly used: White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown.

Step 5: Trim and Insert
Trim the wires to approximately 12mm length and insert them into the shielded RJ45 connector. Ensure the drain wire makes contact with the connector's metal shield.

Step 6: Crimp the Connector
Use a quality crimping tool to secure the connection. The crimping action should compress both the wire contacts and the shielding connection simultaneously.

Common Mistakes to Avoid

• Excessive untwisting: Untwisting pairs more than 13mm can degrade signal quality and increase crosstalk
• Ignoring the shield: Not properly grounding the shield defeats the purpose of using shielded cable
• Wrong connector type: Using unshielded connectors on shielded cable eliminates EMI protection
• Poor crimping: Inadequate crimping pressure can cause intermittent connections
• Jacket not in connector: The outer jacket should extend into the connector for strain relief
