Black Box 4ft GigaTrue Cat6 550MHz Ethernet Patch Cable (Red)

The Black Box EVNSL643-0004 is a four-foot Cat6 patch cable that has been tested to 550 MHz, giving you headroom beyond standard Cat6 requirements for smooth Gigabit Ethernet performance. It connects devices that require dependable, high-speed data transfer, such as switches, routers, servers, desktop computers, or network-attached storage.

The cable uses 24 AWG stranded copper conductors inside an unshielded twisted pair design to balance flexibility with solid signal integrity. Each end carries an RJ45 plug with 50-micron gold-plated contacts that protect against corrosion and help keep packet loss to a minimum. Snagless boots cover each latch so the connectors slide easily through crowded patch panels without catching or breaking.

Its red jacket is useful when you want to trace individual links quickly in a rack, classroom, or home office. Network administrators can assign the color to a specific VLAN or device type, while home users might choose it simply to keep a gaming console or smart-TV connection distinct from everything else.

Whether you are expanding a data center, refreshing office infrastructure, or swapping out a worn cable behind a home router, this model delivers reliable performance in a length that keeps excess slack to a minimum.
