2 Pack RJ45 Female to Female Ethernet Surge Protector, Outdoor LAN Network Surge Arrester, Lightning Protection Inline Extension Coupler Adapter

This package comes with 2 pieces of RJ45 inline surge protectors, integrating cable extension and lightning surge protection into one compact device. Designed as female-to-female coupler style, it can connect two ethernet cables to lengthen network wiring while effectively blocking lightning surges, static electricity and voltage surges transmitted via network lines.

Built with professional surge absorption components, it greatly reduces the risk of burnt-out routers, POE IP cameras, switches and other wired equipment caused by thunderstorms or unstable power grids. The sturdy outer shell adapts to outdoor surveillance wiring, courtyard network layout and cross-wall exposed cable deployment.

It adopts universal 8P8C RJ45 pin layout and works well with Cat5, Cat5e, Cat6 and Cat7 network cables. Featuring plug-and-play design, users just need to insert ethernet cable ends into both sides without complicated configuration. Ideal for home outdoor monitoring systems, factory peripheral network equipment and remote workshop wired network protection.
