UGREEN RJ45 Coupler 10Gbps Ethernet

Quick overview

This compact UGREEN RJ45 coupler joins two existing Ethernet cables to extend a network run while keeping speeds up to 10Gbps according to the manufacturer. It is a simple inline female to female connector that works with Cat7, Cat6, Cat5e and Cat5 cables, and it plugs straight into standard RJ45 terminated leads for an immediate connection. It’s useful when a single cable falls short or when neat routing is needed in a home or small office setup.

Tech specs

• Name: UGREEN RJ45 Coupler
• Type: Female to female Ethernet connector
• Format: Inline coupler
• Compatibility: Cat7, Cat6, Cat5e, Cat5
• Material: Aluminium outer shell, PVC inner shell

Benefits

The aluminium outer case and internal metal shielding reduce electromagnetic interference and help keep a steady signal across the join. Because the coupler supports transmissions over distances of up to 100 metres, it preserves throughput for long runs when used with appropriate cable. The unit is small and unobtrusive so it fits behind furniture or inside wall decor cut-outs, and the robust build is aimed at regular use rather than occasional fiddling. A minor caveat is that any join introduces a potential point of failure, so ensure connectors are fully seated to maintain performance.

Best use cases

It suits situations where you need to extend an existing terminated cable without re‑terminating or running a fresh length. You’ll like it if you want a quick, low-cost fix for shortfalls in cable length, temporary network layouts, or tidy permanent installations where drilling or extra cable runs are impractical. For mission‑critical links consider a single continuous cable run where possible for maximum reliability.
