CAT6A Unshielded Coupler/Johner

Introduction

This CAT6A UTP Coupler is a high-performance, inline RJ45 female-to-female adapter designed to join two unshielded Cat6A patch cables while maintaining full 10 Gigabit Ethernet performance. Compact and easy to use, it provides a reliable solution for extending cable runs, creating temporary connections, or adapting installations without sacrificing network speed or signal quality. Ideal for offices, data centres, and structured cabling environments where unshielded twisted pair (UTP) cabling is deployed.
