RJ45 Coupler StarTech.com IN-CAT6-COUPLER-U1 Cat6 F/F High-Speed Data Transfer

The StarTech.com RJ45 Coupler IN-CAT6-COUPLER-U1 joins two Cat6 Ethernet cables via female-to-female RJ45 connectors to extend a wired network connection. Designed for Cat6 performance, the inline coupler preserves signal integrity and achieves low insertion loss to support high-speed data transfer across extended cable runs.

Advantages

This Cat6 coupler supports multi-gigabit and legacy Ethernet speeds, including 10Gbps, 1Gbps and 10/100, and is compatible with standards such as 10/100/1000BASE-T plus 2.5GBASE-T and 5GBASE-T. The unit features a durable polycarbonate housing and gold-plated phosphor bronze contacts to ensure reliable electrical contact and long-term durability. Its unshielded design allows broad compatibility with common Ethernet patch cables.

Suitable for

• Extending existing Cat6 or lower-category Ethernet cable runs
• Temporary or permanent network cable repairs
• Home, office, or small-data-network patching where a simple inline connection is needed

How to use

Insert the RJ45 plug of one Cat6 cable into one end of the coupler and insert the second cable into the opposite end until each plug clicks into place. Verify the network link lights on connected devices or switches to confirm a successful connection. For optimal performance, use Cat6 cables and avoid excessive cable bends or damage at the connection points.

Usage recommendations

Use this inline coupler for short extension runs and quick repairs; for permanent or long-distance installs, consider a continuous properly-terminated cable to minimize potential signal degradation.
