Keystone RJ45 to RJ45 Coupler FX-RJ45-G/RJ45-G-B – no brand

Keystone RJ45 to RJ45 coupler FX-RJ45-G/RJ45-G-B is a compact keystone-format adapter that links two Ethernet RJ45 cables inside standard keystone wall plates or patch panels. It enables inline extension or temporary connection of network cables without soldering or special tools, providing a simple mechanical join for copper Ethernet leads in structured cabling setups.

Advantages

This keystone coupler offers a space-saving, modular solution compatible with standard keystone openings. It allows fast on-site extension or reconfiguration of Ethernet runs while maintaining a neat installation within faceplates or patch panels. The unit supports tool-free insertion and removal, simplifying maintenance and cabling changes. Its design reduces the need for additional cabling runs when bridging short gaps between existing Ethernet cables.

Suitable for

• Extending or joining Ethernet cables in wall plates
• Temporary network joins during repairs or testing
• Patch panel or faceplate installations in offices and homes
• Situations requiring a keystone-format, snap-in connector

Key specifications

• Connector type: RJ45 female to RJ45 female
• Form factor: Keystone module compatible with standard keystone openings
• Application: Copper Ethernet cable coupling for structured cabling
• Installation: Snap-in keystone mounting for faceplates and patch panels
• Usage: Tool-free insertion and removal for quick changes

How to use

Insert the coupler into a compatible keystone opening on a faceplate or patch panel until it snaps into place. Plug one RJ45 cable into each side of the coupler to create an inline connection. For temporary connections, insert and remove cables as needed; for permanent installations, ensure the module is seated firmly in the wall plate or panel to prevent accidental disconnection. Verify network link and performance after connection using standard network testing tools.

Usage recommendations

Use the coupler for short-term extensions or where minimal signal loss is acceptable. Avoid using it as a replacement for properly terminated cable runs in high-performance or long-distance Ethernet links—where certified patch cords or properly punched keystone jacks are preferred. Keep the connection area free from excessive strain and secure cables to reduce mechanical stress on the coupler.
