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

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.
