10 Pack Black Inline RJ45 Female to Female Ethernet Coupler, Cat7/Cat6/Cat5e Universal 8P8C LAN Cable Extension 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 cables together to lengthen your network line without replacing long new cables. It supports high-speed transmission standard up to Cat7 and backward compatible with Cat6 and Cat5e cables, delivering stable gigabit signal for online gaming, 4K video streaming, large file transfer and security monitoring systems. Gold-plated terminals lower contact resistance and resist oxidation to maintain reliable long-term connection. No drivers or external power supply required, just plug two Ethernet patch cords into both ends for instant network access.

The integrated solid housing effectively blocks external electromagnetic interference to avoid slow network speed and disconnection. Mini lightweight structure saves space, perfectly suitable for home network layout, office wiring renovation, dormitory cable sorting and security monitoring room construction.
