## Long description

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.
