10Gtek SFP+ DAC Cable 3m Passive 10GbE network ethernet cable

10GbE SFP+ Direct Attach Copper Cable 3 m

This passive twinax cable carries a 10 GbE signal between two SFP+ ports over a 3 metre length. It is built for short-range links inside a rack or between adjacent racks where fibre would add cost and power draw. The assembly suits network-attached storage, storage-area networks and high-performance computing clusters. Buyers who need longer runs or active signal conditioning will need a different cable type.

Check SFP+ port compatibility and link distance

Verify that both endpoints have SFP+ cages and support passive copper at 10.3 Gb/s. The supplier notes that Intel NICs linked over 3 metres may require 24 AWG cable for stability, while 30 AWG is acceptable for shorter spans. Ensure the 3 metre reach matches the physical layout of your rack or row. Do not assume compatibility with proprietary or locked-down switch firmware without testing.

Tested signal integrity and manufacturer support

Every unit passes time-domain reflectometry and vector-network-analyser checks in the vendor’s signal-integrity lab and is individually tested on switches before shipment. The cable ships with a 30-day free-return window, a three-year warranty and lifetime technical support from the manufacturer. Customised cable assemblies are also available for specialised deployments.
