Couplers

Cat5 and Cat6 couplers are devices used to connect two Ethernet cables while maintaining their respective performance standards. Cat5 couplers are compatible with Category 5 cables that support speeds up to 1 Gbps. Cat6 couplers, on the other hand, are designed for Category 6 cables that can handle speeds up to 10 Gbps.   

Both feature female RJ45 connectors and are commonly used to extend or join network cables in various applications.
