Shielded RJ45 Coupling ROLINE 21.17.3101 Cat.6A Silver, inline adapter for shielded Ethernet

ROLINE 21.17.3101 is a shielded RJ45 inline coupling designed for Cat.6A networks. The compact silver adapter connects two shielded Ethernet cables or patch cords without re-terminating, preserving the cable shielding and maintaining signal integrity for high-speed links up to 10 Gigabit. Its metal housing ensures continuity of the shield and reduces electromagnetic interference in structured cabling installations.

Advantages

The inline adapter provides a reliable, compact, and tool-free way to extend or join shielded Ethernet runs while preserving the shield continuity required for Cat.6A performance. Its robust metal enclosure offers mechanical protection and helps to reduce crosstalk and external interference. The adapter supports full 10 Gigabit Ethernet speeds and is suitable for environments where maintaining a continuous shield is important for network stability and noise reduction.

Suitable for

• Extending shielded Cat.6A patch cords without re-terminating
• Temporary or permanent inline connections in data centers and network closets
• Maintaining shielding continuity in environments with high electromagnetic interference
• Compact passthrough connections in structured cabling and patch panels

Key specifications

• Connector type: shielded RJ45 coupling, inline adapter
• Category: Cat.6A compatible
• Data rate support: up to 10 Gigabit Ethernet
• Housing material: metal (shielded)
• Finish: silver
• Contact configuration: 8P8C compatible
• Mounting style: inline, pass-through between two patch cords

How to use

Align the two shielded RJ45 plugs from the cables or patch cords with each end of the coupling and insert them until they click into place. Ensure that the outer shields of the cable connectors make firm contact with the metal body of the adapter to preserve shielding continuity. Use the coupling as an inline, pass-through connection; no crimping or re-termination of cable ends is required. Verify link status and network performance after installation.

Usage recommendations

For best results use with shielded Cat.6A cables and shielded connectors; avoid exposing the adapter to prolonged moisture or mechanical strain. When used in permanent installations, position the coupling in a protected location such as a patch panel area or cable management tray to prevent accidental disconnection and physical damage.
