Ubiquiti UniFi RJ45 Cat6A Coupler – Indoor (UACC-RJ45-Coupler-C6A)

The Ubiquiti UniFi RJ45 Cat6A Coupler – Indoor (UACC-RJ45-Coupler-C6A) is a compact, high-performance connectivity solution designed to extend Ethernet runs within structured, indoor network environments. Specifically engineered for use with Cat6A RJ45 cables, this coupler provides a secure and low-loss method to join two Ethernet cables, enabling longer network connections without the need to re-terminate or replace existing cabling.

This coupler is ideal for enterprise networks, office buildings, and commercial IT spaces where reliable internal connectivity is essential. Whether you're extending a patch cable between two switches, adding length to reach a new desk, or linking through-wall cable runs, the UACC-RJ45-Coupler-C6A ensures a clean and professional-grade connection. It supports up to 10 Gigabit Ethernet speeds, maintaining excellent signal integrity with minimal insertion loss or interference.

The core of the coupler is built to strict Cat6A specifications, which means it features precision-aligned internal contacts to support high-speed data transmission with reduced crosstalk and EMI (electromagnetic interference). This results in consistent performance in environments with dense cabling or nearby electronic equipment. The coupler also fully supports PoE (Power over Ethernet), allowing both data and power to pass through without disruption—an important feature for UniFi access points, VoIP phones, and other powered network devices.

The UACC-RJ45-Coupler-C6A features a compact, tool-free design that makes it easy to install in seconds. Simply insert the RJ45 connectors from each cable into the coupler’s jacks until they click into place. There’s no need for crimping tools, keystone jacks, or wall plates—making it ideal for quick fixes, temporary setups, or expansions where time and flexibility matter. Its small size also makes it easy to conceal behind desks, inside cable trays, or within junction boxes for clean and organized installations.

Designed to match the quality standards of the UniFi ecosystem, this coupler delivers reliable performance across a wide range of UniFi-compatible devices and cables. It ensures that your network extensions maintain the same level of stability and speed expected from a fully integrated Ubiquiti deployment.

For IT administrators, installers, and support teams, the Ubiquiti UniFi RJ45 Cat6A Coupler – Indoor is a simple yet invaluable accessory. It offers a fast, professional way to connect and extend Ethernet lines with zero compromise on performance. Whether for permanent installations or quick fixes in an expanding network, this coupler helps keep your infrastructure connected, efficient, and future-ready.
