ROLINE Mini-Inline Coupler Cat6A STP, silver, model 21.17.3116

ROLINE Mini-Inline Coupler Cat6A STP, silver (model 21.17.3116) is a compact inline adapter engineered to join two shielded Cat6A patch cables quickly and without tools. The coupler preserves the foil and drain continuity of STP cables to maintain shielding integrity and support high-speed Ethernet links up to Cat6A performance. Its slim metal housing and silver finish make it suitable for tight spaces such as patch panels, wall outlets and equipment racks while providing a stable mechanical and electrical connection for short extensions and emergency repairs.

Advantages

The mini-inline design enables convenient, tool-free coupling of two Cat6A STP cables while maintaining the cable shielding and minimizing signal degradation. A sturdy metal housing provides mechanical protection and helps with electromagnetic compatibility. Its compact footprint allows installation in crowded racks or behind equipment where space is limited, and the device supports full Cat6A bandwidth for 10 Gigabit Ethernet applications over appropriate cable runs.

Suitable for

• Patching two Cat6A STP patch cords in server rooms and office networks
• Short cable extensions where replacing a cable is impractical
• Quick link repairs during installations and maintenance
• Use in equipment racks, data cabinets and behind networking hardware

Key specifications

• Category: Cat6A shielded twisted-pair (STP) inline coupler
• Connector type: RJ45 coupling for shielded RJ45 plugs
• Shielding: Metal housing preserving cable foil/drain continuity
• Performance: Supports Cat6A performance and bandwidth for high-speed Ethernet
• Color and finish: Silver metal housing
• Form factor: Compact, low-profile inline coupler for tight spaces

How to use

Ensure both patch cable plugs are clean and the shielding drain wires are correctly positioned in the cable plugs. Insert the first shielded RJ45 plug into one side of the coupler until it clicks, then insert the second plug into the opposite side. Confirm both connections are secure and that the metal housing contacts the cable shield where possible to maintain continuity. Use the coupler for short links and temporary extensions; for permanent infrastructure changes, consider replacing with a single continuous cable run.

Usage recommendations

For best signal integrity, use the coupler only with Cat6A STP patch cords of matching shield type and maintain proper cable routing to avoid excessive bends. Avoid using the inline coupler for long permanent runs; limit its use to patching, short extensions and temporary repairs in controlled environments such as server rooms and network cabinets.
