Black Box CAT6 25ft Shielded Ethernet Cable (Black)

The Black Box EVNSL0272BK-0025 is a Category 6 Ethernet cable built for installations where electromagnetic interference threatens network reliability. At a length of 25 ft, it links switches, routers, servers, or Power over Ethernet devices without forcing you to add couplers that can slow a Gigabit signal.

Inside a jacket made from black PVC, aluminum mylar foil surrounds every pair and a tinned copper braid wraps the entire assembly. This dual layer forms a strong barrier against radio-frequency noise that often appears in manufacturing floors, broadcast studios, or home offices positioned near heavy appliances. Because the cable is flame retardant and rated for indoor or outdoor runs, you can route it through a ceiling tray, along an exterior wall, or directly to outdoor security cameras and still meet common safety codes.

The RJ-45 plugs use 50-micron gold plated contacts that maintain low resistance after up to 750 insertions. That means you can reconfigure a rack or swap out hardware again and again without worrying about worn contacts or intermittent drops. Every assembly is factory tested to 250 MHz, so it passes the bandwidth that Gigabit Ethernet demands with headroom to spare. Compliance with RoHS, EN 50173-1, IEC 60332-1, and ISO/IEC 11801 standards offers added peace of mind in regulated environments.

Choose this cable when you need a straightforward way to move data at Gigabit speed through a noisy space, whether you are extending a backbone in a data center, building a video editing suite, or wiring a small office that shares a wall with machinery. The lifetime limited warranty from Black Box underscores its role as a long-term part of your network toolkit.
