Network adapter Renkforce RF-4981662 RJ45 coupler Cat 5e metal, female-to-female inline

Inline RJ45 coupler Renkforce RF-4981662 is a metal female-to-female adapter designed for Cat 5e Ethernet connections. The compact inline design allows two RJ45 patch cables to be joined quickly and without reterminating connectors, enabling simple extension of existing network runs. Constructed with a metal housing, the coupler provides a durable connection point for home and office wired networks and is compatible with Cat 5e cabling for up to Gigabit performance where the attached cables and network devices support those speeds.

Advantages

The metal housing increases mechanical durability and shielding compared with plastic couplers, reducing the risk of connector damage and providing stable performance in typical indoor network environments. The female-to-female inline format requires no tools or crimping and keeps cable ends protected while maintaining a straightforward plug-and-play connection. Compatibility with Cat 5e cabling preserves signal characteristics for speeds up to 1 Gbit/s when the rest of the infrastructure supports it.

Suitable for

• Extending Ethernet runs by joining two RJ45 patch cables
• Temporary network setups and quick troubleshooting where reterminating is impractical
• Home networks, small offices, and IT racks where compact inline connections are needed
• Connecting devices across short distances without modifying existing cables

Key specifications

• Cable category: Cat 5e
• Connector type: RJ45 female-to-female (inline)
• Housing material: metal
• Supports up to: Gigabit Ethernet speeds where cabling and devices permit
• Form factor: compact inline coupler for patch cables

How to use

To use the coupler, simply insert the RJ45 plug of one patch cable into one end of the adapter and insert a second RJ45 plug into the opposite end. Ensure both cables are fully seated until they click into place to maintain a reliable connection. Position the joined cables so that the coupler is not under mechanical stress or repeated bending, and avoid placing it in areas with excessive moisture or dust. No tools, termination, or configuration are required; the connection is immediate and ready for network traffic.

Usage recommendations

Use the metal inline coupler indoors in standard environmental conditions and as a temporary or semi-permanent solution for extending patch cable runs. For permanent or performance-critical installations, consider using properly reterminated cables or a wall-mounted keystone jack to minimize connection points and maintain optimal long-term signal integrity.
