Blue 0.5 metre SFP+ DAC twinax cable with SFP+ connectors at both ends

Wiitek

Wiitek 0.5m 10G SFP+ DAC Twinax Cable Blue

SKU CH-FYKS-N3HYX

A .5 m passive SFP+ twinax cable carrying 10 GbE up to 10.5 Gbps with 20-pin hot-pluggable connectors, 30 AWG conductors and 0–70 °C operation

  • Length1.64 ft.
  • 5 m passive twinax keeps latency low for 10 GbE links
  • 5 Gbps data rate supports full 10 GbE throughput
  • Hot-pluggable SFP+ 20-pin footprint enables live port changes
  • Compliant with SFP+ MSA and SFF-8432 for broad switch interoperability
  • Blue AWG30 jacket simplifies cable identification in dense racks

Direct-attach 10 GbE link

The Wiitek passive SFP+ twinax cable provides a 0.5 m copper connection for 10 Gb Ethernet or Fibre Channel links between switches, routers, servers and NICs. It uses a hot-pluggable 20-pin SFP+ footprint and requires no external power. The blue jacket aids cable identification in dense racks.

Steady throughput at 10.5 Gbps

Rated for sustained data rates up to 10.5 Gbps, the assembly remains compliant with the SFP+ MSA and SFF-8432 specifications across the full 0–70 °C operating range. Low crosstalk construction and improved pluggable form factor shielding maintain signal integrity without active equalisation. Backward compatibility to 1 Gbps allows mixed-speed deployments.

Half-metre reach for adjacent ports

At 1.64 ft the cable only spans directly adjacent or same-shelf SFP+ ports; longer runs need active optical or longer copper variants. The fixed AWG30 twinax construction cannot be field-terminated or extended. Buyers needing rack-to-rack distances should select a different length.

Questions about this item

Does the 0.5 m SFP+ DAC generate noticeable heat or draw extra power when run continuously?

The passive twinax design has no active electronics, so it adds virtually no heat and draws negligible power even at 10.5 Gbps all day.

What equipment must already have SFP+ ports for this cable to work?

Both ends need SFP+ sockets — typical gear includes 10 GbE switches, routers, NAS units, NICs or other adapters that accept the 20-pin footprint.

Will the 1.64 ft blue cable link reliably to older 1 Gbps SFP gear I still use?

Yes, the assembly is backward compatible to 1 Gbps and compliant with SFP+ MSA and SFF-8432, so it negotiates down automatically.
