ROLINE RJ45 coupler Cat.6A shielded – in-line network coupler, model 21.17.3118

The ROLINE RJ45 coupler Cat.6A shielded – in-line network coupler (model 21.17.3118) is a female-to-female connector designed to join or extend Cat.6A Ethernet cables while preserving shielding and transmission performance. It provides a compact, pass-through connection that supports high-speed Ethernet links where a shielded RJ45 coupling is required. The coupler is intended for use in structured cabling environments, server rooms, office networks and temporary cable extension scenarios where maintaining Cat.6A characteristics and electromagnetic compatibility is necessary.

Advantages

This shielded in-line RJ45 coupler maintains Cat.6A specifications for high-frequency performance and offers electromagnetic shielding to reduce interference in shielded cabling runs. The female-to-female passthrough design simplifies cable extension or joining without reterminating connectors, allowing quick connection of two RJ45 cables. The compact form factor makes it suitable for tight spaces and easy integration into existing network layouts.

Suitable for

• Extending or joining Cat.6A shielded Ethernet cables
• Temporary network extensions in server rooms or offices
• Shielded Gigabit and 10 Gigabit Ethernet runs
• Situations requiring continued electromagnetic shielding in the link

Key specifications

• Connector type: female-to-female RJ45 in-line coupler
• Cabling class: Category 6A compliance for high-frequency performance
• Shielding: fully shielded design to maintain S/FTP or similar shield integrity
• Application: supports Gigabit and 10 Gigabit Ethernet data rates
• Form factor: compact inline housing suitable for confined installations

How to use

Connect one shielded Cat.6A RJ45 cable to each end of the coupler, ensuring that outer shields make proper contact with the coupler housing to preserve continuity of shielding. Push the plugs fully into the female connectors until the latching tab clicks in place. Verify link integrity and data transmission after installation; perform testing with appropriate network testers if required for certification or troubleshooting.

Usage recommendations

For best results, use the coupler only with shielded Cat.6A cables and maintain proper grounding of the shielded cabling system. Avoid using the coupler as a permanent bulk installation point in high-demand networks; where possible, prefer continuous cable runs or professionally reterminated connections for certified installations.
