Cisco SFP-H10GB-ACU7M — active copper rack run

Select the documented longer active copper assembly when a short passive rack jumper will not reach.

Also called Cisco SFP-H10GB-ACU7M, 7m active twinax

Active copper and active optical are different media even when their integral SFP+ ends look alike.

The useful distinction

Match the complete manufacturer identity, endpoint roles and selected length; a similar shell or cable color is insufficient.

Specifications and limits

Cisco SFP-H10GB-ACU7M — active copper rack run facts and limitations
Documented task / mode10Gb/s direct-attach SFP+ cable; exact platform/OS support remains required. [C988A]
Construction / lengthActive 30AWG twinax copper with integral SFP+ ends; this is a different powered construction from the 1m passive DAC. 7m exact PID, not permission to join passive DACs with couplers or assume all SFP+ ports accept active DACs. [C988A]
Verified device listNot included. Check exact device and accessory documentation.
A boundary, not an omission to guess around.

Active 30AWG twinax copper with integral SFP+ ends; this is a different powered construction from the 1m passive DAC. Rack/adjacent-rack use; exact bending, pull and port thermal/clearance conditions require the selected system documents.

Before you connect

What to check

  1. Record exact PID and both platform/firmware support entries; if only passive DAC support is documented, keep this active choice unresolved.
  2. Check condition with power disconnected where the equipment guidance permits; stop for damage, heat or unknown powered connections.
  3. Keep published source support separate from physical test results.

Direction and fallback

Two-way supported SFP+ Ethernet path. Active construction does not mean a generic media/protocol converter. Lower-rate or alternate-protocol operation is not established by this cable example.

Worked selection example

For a 7m supported SFP+ rack path, assess this active assembly and a supported AOC separately; check host power/compatibility rather than assuming either behaves like passive copper.

What to observe next

Record exact PID and both platform/firmware support entries; if only passive DAC support is documented, keep this active choice unresolved.
