10 Pack Black Shielded RJ45 In-Line Coupler, Female to Female Ethernet Cable Extender, Cat8/Cat7/Cat6/Cat5e/Cat5 Universal LAN Connector Adapter

This 10-pack black RJ45 inline coupler is a practical cable extension accessory with dual female RJ45 ports, used to connect two separate Ethernet patch cords together to lengthen network lines without replacing brand-new long cables.

It meets high-speed transmission standards up to Cat8, and is fully backward compatible with Cat7, Cat6, Cat5e and Cat5 cables, delivering stable gigabit and 40Gbps high-speed signal for gaming, 4K streaming, large file transfer and security monitoring systems. Gold-plated terminals effectively lower contact resistance and prevent corrosion for long-lasting reliable connection.

Universally matched with all mainstream network devices equipped with standard RJ45 ports, including home routers, office switches, desktop computers and surveillance cameras. Plug & play design without drivers or external power supply, just plug two network cables into both ends for instant connection.

The solid black shell with built-in shielding blocks external electromagnetic interference to avoid network lag and disconnection. The 10-piece bulk pack offers outstanding cost performance, ideal for home network layout, office renovation, engineering wiring and monitoring room cable expansion.
