Cisco SFP-H10GB-CU3M – 3 Meter Direct-Attach SFP+ Passive Twinax Copper Cable

Cisco SFP-H10GB-CU3M is a 3-meter direct-attach SFP+ passive twinax copper cable designed for reliable, high-speed 10 GbE connectivity in data centers and enterprise networks.

As a 10GBASE-CU cable, it provides a cost-efficient and low-latency solution for connecting switches, servers, or storage within the same rack or between adjacent racks.

Because it is a passive DAC, it consumes very little power and avoids the complexity of optical transceivers, delivering plug-and-play simplicity.

The shielded twinax cable ensures stable signal transmission and robust performance.

This cable is especially suited for short-range interconnections where fiber may not be necessary, helping reduce network costs and complexity.

FAQ For Cisco SFP-H10GB-CU3M

Q1: What is the length of this cable?

A: The cable is 3 meters long.

Q2: Is this a passive or active cable?

A: It is a passive twinax copper DAC (Direct-Attach Cable).

Q3: What data rate does it support?

A: It supports 10 Gbps (10GBASE-CU) connections.

Q4: Can I use it with non-Cisco devices?

A: Yes — as long as the device has an SFP+ port that supports passive DAC cables. However, compatibility is best with Cisco or DAC-friendly hardware.

Q5: What kind of link is this ideal for?

A: Short-range links such as rack-to-rack, switch-to-server, or switch-to-switch connections within the same data center room.

Q6: Does it require special power or transceivers?

A: No — it’s a passive cable, so no external power or transceivers are needed beyond the SFP+ cage on each end.
