Coupler VALUE RJ45 Category 6A Shielded, model 21.99.3014 — inline female-to-female network coupler

Shielded VALUE RJ45 Category 6A inline coupler, model 21.99.3014, is a female-to-female network adapter designed to connect two RJ45 patch cables while preserving shielding and meeting Category 6A channel performance. The coupler provides a compact connection point for temporary cable extensions or in locations where running a single longer cable is impractical. Its shielded construction reduces electromagnetic interference (EMI) and helps maintain signal integrity for high-speed 10 Gigabit Ethernet links within structured cabling environments, patch panels and wall outlet extensions.

Advantages

The shielded metal housing ensures continuous grounding between connected shielded patch cords and lowers susceptibility to external EMI sources. The product supports Category 6A performance parameters, enabling reliable transmission for 10 Gigabit Ethernet over the connected channel when used with compatible cables and hardware. Its compact inline female-to-female design requires no tools for connection and allows quick, temporary joins of existing patch cables without modifying installed infrastructure.

Suitable for

• Temporary extension of Ethernet runs where a longer cable is not available
• Joining two shielded RJ45 patch cables in a structured cabling system
• Use in patch panels, wall outlet areas, server racks or workstations
• Environments with increased EMI where shielding continuity is required

Key specifications

• Connector type: RJ45 female to RJ45 female inline
• Cabling category: Category 6A compliant performance
• Shielding: Shielded metal housing to maintain STP/FTP continuity
• Supported data rate: Suitable for 10 Gigabit Ethernet channel use
• Use case: Inline adapter for patch cords and temporary cable joins
• Mounting/installation: Tool-free inline connection between two patch cables

How to use

Ensure both patch cables are shielded and compatible with Category 6A performance. Align the RJ45 plugs of each cable with the female connectors of the coupler and insert firmly until the plugs click into place. Verify continuity of shielding by confirming that the connected equipment is properly grounded. Use the coupler for temporary joins or quick repairs; for permanent installations, consider using dedicated cabling runs or wall-mounted outlets that preserve structured cabling best practices.

Usage recommendations

To maintain Category 6A channel performance and shielding benefits, use shielded RJ45 patch cords and ensure proper grounding at both ends. Avoid using the coupler in long-term or mission-critical backbone segments; prefer fixed cabling and professionally terminated outlets for permanent installations. Inspect connectors for damage before use and replace the coupler if mechanical wear or poor contact is observed.
