Cisco SFP-H10GB-CU3M= 10GBASE-CU SFP+ Cable 3 m | Twinax, Enterprise — SFP-H10GB-CU3M=

Add reach without adding complexity with Cisco’s 3 m SFP+ copper twinax cable. Built for direct-attach 10 GbE links, it is a strong fit when adjacent equipment is not perfectly aligned or when you need extra slack for cleaner routing through rack channels and vertical managers. At 3 m, this cable gives you more placement freedom than shorter assemblies while staying within the practical range for short-distance copper interconnects. That makes it useful for switch-to-server, switch-to-storage, and switch-to-switch connections where optical modules would be unnecessary overhead. The SFP+ connectors on both ends support straightforward deployment in Cisco-aligned environments, and the copper twinax construction keeps the link compact and serviceable. In dense racks, that matters: fewer components, less cable bulk, and easier access during maintenance. Choose the 3 m version when the 1 m cable is too tight and you still want a purpose-built direct-attach option for 10 GbE. It is the right balance of reach and simplicity for enterprise teams standardizing short-run interconnects across racks and row segments. Ideal For Connect a server to a switch when the rack layout needs extra slack Route 10 GbE links through cable managers in adjacent racks Link storage systems to switching infrastructure in dense enclosures Replace optical cabling for short-distance direct-attach deployments Why This Product 1 Longer 3 m reach for flexible rack routing 2 Copper direct-attach design instead of optics 3 SFP+ ends on both sides for simple compatibility 4 Cisco-branded cable for standardized deployments
