RJ-45 Coupler ROLINE Model 21.17.3113 Unshielded Category 6 Inline Network Coupler

ROLINE RJ-45 Coupler Model 21.17.3113 is an inline, unshielded Category 6 network coupler designed to join two Ethernet cables with RJ-45 plugs. The compact, tool-free connector provides a simple way to extend cable runs or adapt layouts for gigabit networks where shielded cabling is not required. Its unshielded design is suitable for typical office and home environments and maintains Cat6 performance across the joined connection when used with compatible Cat6 cables.

Advantages

The coupler enables a quick, tool-free extension of Ethernet runs without terminating or repatching existing cables. Its compact inline form factor minimizes space requirements and can be used for temporary or semi-permanent connections. Designed to preserve Category 6 signal characteristics, the coupler supports gigabit Ethernet performance when installed with Cat6 patch cords. The unshielded construction simplifies installation in environments where additional shielding is unnecessary.

Suitable for

• Extending Ethernet cable runs in office and home networks
• Temporary network setups and testing environments
• Connecting patch cords behind desks, routers, or wall outlets
• Situations where a compact, tool-free inline connection is preferred

Key specifications

• Cable category: Category 6 (Cat6) unshielded
• Connector type: RJ-45 female to RJ-45 female inline coupler
• Supported data rates: up to gigabit Ethernet (1000BASE-T) when used with Cat6 cabling
• Construction: compact, plastic unshielded housing
• Installation: tool-free plug-and-play inline connection

How to use

To use the coupler, insert the RJ-45 plug of the first Ethernet cable into one end of the coupler and the RJ-45 plug of the second cable into the opposite end until each plug clicks into place. Ensure both cables are Category 6 to achieve Cat6 performance. There are no tools or termination steps required; the connection is immediate and can be disconnected by pressing the connector clip and pulling the plug out when needed.

Usage recommendations

For optimum performance, use the coupler with high-quality Cat6 patch cords of appropriate length and avoid placing the coupler in areas with strong electromagnetic interference. For permanent installations or environments requiring improved noise immunity, consider using shielded connections or professionally terminated cabling instead of an unshielded inline coupler.
