Keystone RJ45 Coupler FX-RJ45-8, no-brand, modular insert for Ethernet keystone jacks

Keystone RJ45 coupler FX-RJ45-8 is a modular insert designed for use in keystone-compatible housings such as patch panels, wall plates and surface-mount boxes. It provides a female-to-female RJ45 connection in an 8-position keystone format for Ethernet cabling, enabling simple extension or joining of two Ethernet cables without altering terminations. The unit is intended for structured cabling and small network installations where keystone modularity is required.

Advantages

The keystone format allows quick snap-in installation into standardized panels and faceplates, preserving a clean and modular network layout. By providing a female-to-female RJ45 interface, the coupler eliminates the need to re-terminate existing cables when extending a link. Its compact design occupies a single keystone port space, making it suitable for high-density installations and easy replacement or reconfiguration.

Suitable for

• Extending or joining Ethernet patch cables
• Filling an RJ45 keystone port in patch panels or wall plates
• Temporary or permanent link changes in small office or home networks
• Modular network installations requiring standardized keystone components

Key specifications

• Format: RJ45 female-to-female keystone insert (8-position)
• Compatibility: Fits standard keystone openings in panels, faceplates and housings
• Cabling: Suitable for Ethernet twisted-pair cables (UTP/STP) terminated with RJ45 plugs
• Installation: Snap-in keystone mounting, occupies one keystone port
• Material: Durable insulating housing designed for indoor network installations

How to use

Insert the module into a compatible keystone opening until it snaps into place. Plug RJ45 terminated cables into each side of the coupler to join two network segments or to provide an accessible connection point on a faceplate or patch panel. Ensure connectors are fully seated and that cable twists and bends near the connection follow good cabling practice to maintain signal integrity.

Usage recommendations

Use the coupler for short extension runs or where modular convenience is required; for long permanent links, prefer a single continuous cable or properly terminated ends to minimize potential signal loss. Verify cable category compatibility (Cat5e, Cat6, etc.) between connected cables to maintain required network performance.
