Start with what is physically represented

Two-way supported SFP+ Ethernet path. Active construction does not mean a generic media/protocol converter.

Choose for the actual job

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

ConstructionDocumented

Active 30AWG twinax copper with integral SFP+ ends; this is a different powered construction from the 1m passive DAC.

Evidence: C988A

Fallback / lower modesConditional

Lower-rate or alternate-protocol operation is not established by this cable example.

Evidence: C988A

Environment and handlingConditional

Rack/adjacent-rack use; exact bending, pull and port thermal/clearance conditions require the selected system documents.

Evidence: C988A

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.

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

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

Source-documented example; no hardware test

Capability ledger

Six questions kept separate

DataDocumented

10Gb/s direct-attach SFP+ cable; exact platform/OS support remains required.

Evidence: C988A

Power / chargingDocumented

Cisco lists 1W consumption for this PID. No endpoint charging or PoE delivery is represented.

Evidence: C988A

VideoNot Applicable

No native display mode represented.

ConversionActive

Active 30AWG twinax copper with integral SFP+ ends; this is a different powered construction from the 1m passive DAC.

Evidence: C988A

Length / reachDocumented

7m exact PID, not permission to join passive DACs with couplers or assume all SFP+ ports accept active DACs.

Evidence: C988A

Markings / certificationConditional

Read ACU7M in the complete PID; do not substitute a CU passive cable on name similarity.

Evidence: C988A

Explicit unknowns
  • No physical sample, electrical/optical measurement or hardware interoperability test was performed.
  • Record exact PID and both platform/firmware support entries; if only passive DAC support is documented, keep this active choice unresolved.
