Direct-attach 10 GbE link

This passive SFP+ twinax cable provides a 10 Gbps Ethernet or Fibre Channel connection between switches, routers, servers and storage appliances. It is built for data-centre racks and high-density wiring closets where short, low-latency links are required. The assembly targets network engineers and system integrators deploying 10GBase-CU infrastructure.

Passive thermals and power

With no active electronics the cable draws zero power and generates no heat beyond the minimal resistance of its 30 AWG conductors. It operates reliably across a 0 to 70 °C (32 to 158 °F) ambient range and produces no fan noise. Compliance with SFP+ MSA and SFF-8432 ensures consistent signal integrity without additional cooling.

One-metre reach constraint

The fixed 9.84 ft length suits adjacent rack units or equipment within the same cabinet but cannot span longer row or aisle distances. Buyers needing extended runs must choose active optical cables or transceivers with fibre patch leads instead.

Questions about this item

How do I install the 30 AWG SFP+ to SFP+ passive twinax cable without damaging the connectors?

Align the keyed SFP+ ends with the switch or NIC ports, push straight in until the latch clicks, and avoid bending the 30 AWG twinax tighter than the cable's natural curve during routing.

What maintenance or replacement will the 1-meter passive twinax cable need over time?

Inspect the SFP+ latch tabs and PVC jacket periodically; replace the cable if the latch no longer secures firmly or if the jacket shows cracks after repeated temperature cycles between 0 and 70°C.

What is the first limit that appears when the 10 Gbps SFP+ DAC runs continuously at high load?

The 30 AWG copper conductors and passive design mean signal integrity degrades first if the link exceeds the 1-meter specification or operates near the 70°C upper temperature limit for extended periods.
