Short black twinax cable with SFP+ connectors on both ends

Wiitek

Wiitek 10Gb SFP+ DAC network ethernet cable 1.64 ft passive twinax 30AWG

SKU CH-E9ZF-T2ZVX

A 1.64 ft passive twinax cable linking two SFP+ ports at 10 Gbps for switch-to-server or storage connections

  • Overall length1.64 ft (0.5 m)
  • 10 Gbps throughput over a 1.64 ft passive twinax link
  • 30 AWG copper conductors keep crosstalk low for reliable signals
  • Operates from 0 to 70 °C (32 to 158 °F) in rack environments
  • Compliant with SFP+ MSA and SFF-8432 for broad vendor interoperability
  • Connects switches, routers, NAS and NICs with SFP+ ports directly

10Gb SFP+ passive DAC cable

This 1.64 ft passive twinax cable provides a direct 10 Gbps link between two SFP+ ports. It suits installers who need a short, low-latency copper connection for switches, routers, NAS appliances or network interface cards.

Passive twinax length constraint

Passive copper twinax is practical only for very short runs such as rack-to-rack or within a single cabinet. The 1.64 ft length fits adjacent devices but cannot span longer distances where active or optical cables become necessary.

30 AWG wire gauge

The 30 AWG conductors determine the cable's flexibility and its maximum reliable reach at 10 Gbps. Builders who need longer passive runs or tighter bend radii must verify that this gauge meets their physical routing requirements.

Questions about this item

Should I choose the 1.64 ft passive twinax cable or a longer version for my 10Gb SFP+ link?

The 1.64 ft (0.5 m) length suits adjacent rack devices; select a longer passive cable only if the run stays within the 30 AWG twinax reach for 10 Gbps.

What does the 10 Gbps headline rate deliver once the cable is installed in a switch?

It provides a full 10 Gbps Ethernet or Fibre Channel link between two SFP+ ports with no power draw from the cable itself.

Which interface standard governs the SFP+ connectors and what does it cap in practice?

The SFP+ MSA and SFF-8432 standards define the mechanical and electrical interface, capping passive copper reach at the rated length for 10 Gbps operation.
