3-metre 10 GbE SFP+ DAC cable

This 3-metre passive twinax cable carries 10 GbE between two SFP+ ports. It suits network-attached storage, storage-area networks and high-performance computing links inside or between adjacent racks. The assembly is tested to TDR and VNA standards before shipping.

Check SFP+ port availability and spacing

Verify that both endpoints expose SFP+ cages and that the 9.84 ft reach covers the rack distance without strain. The cable is passive and draws no external power, so no power budget is consumed. Ensure the host firmware accepts third-party DAC modules.

Sustained 10 GbE throughput with low latency

Passive copper construction keeps latency minimal and power draw near zero during continuous 10 GbE streams. The 100-ohm impedance and AWG24 conductors maintain signal integrity across the full 3-metre run. Operation is specified from 0 to 70 °C without active cooling.

Questions about this item

Does the 3-metre twinax cable arrive with both SFP+ connectors already fitted, or must I buy the modules separately?

The cable has SFP+ connectors permanently attached at each end, so no separate transceivers are required.

The range lists 0.82 ft to 16.4 ft; when should I pick the 3-metre version instead of a shorter or longer one?

Choose the 3-metre length when the switch and server or NIC are in the same rack or adjacent racks and the 9.84 ft reach matches that spacing.

The spec says 10 GbE and 100-ohm impedance — what throughput will I actually see on a live 10G link?

The passive twinax assembly is tested to IEEE 802.3ae and supports the full 10 Gbit/s line rate with low power draw and EMI performance suitable for 1–10 G multi-rate links.
