Cisco 33ft SFP+ Copper Twinax Network Cable

The Cisco SFP-H10GB-ACU10M= is a direct attach cable that connects one SFP+ port to another over a distance of 33 ft. It relies on copper conductors arranged in a twinaxial layout, a choice that keeps latency low and preserves signal integrity for short-reach links inside the rack or between adjacent racks.

Because each end already carries an SFP+ connector, network teams can establish a 10 Gigabit link without separate transceivers or fiber patch cords. Seat one end in a Cisco switch, router, server, or storage appliance, click the other end into a matching port, and the connection is ready in seconds.

The cable fits naturally in data centers that run Cisco Nexus, Catalyst, or UCS equipment. It suits top-of-rack aggregation, spine-leaf interconnects, lab environments, and any deployment that needs reliable bandwidth across a modest span. The black jacket blends with common cable management schemes, while the 33 ft length offers enough slack to reach overhead trays or underfloor pathways without excessive coil.

By using a passive twinax design, the cable draws less power than comparable short-distance optical links and contributes to cooler, more efficient racks. Network engineers who value simplicity, predictable performance, and quick installation will find it a straightforward tool for high-speed data movement.

Highlights:

• Length of 33 ft provides flexibility for in-rack or between-rack routing
• Direct attach design connects two SFP+ ports without separate transceivers
• Construction that uses twinaxial copper conductors to maintain low latency
• Compatible with Cisco Nexus switches, Catalyst switches, and UCS servers
• Supports high-bandwidth traffic across short distances in data centers
