This StarTech.com HPE J9283B Compatible 3m 10G SFP+ to SFP+ Direct Attach Cable Twinax – 10GbE SFP+ Copper DAC 10 Gbps Low Power Passive Mini GBIC/Transceiver Module DAC Firepower… offers a direct copper link for short-range 10GbE network connections. It is designed for use with HPE® brand compatible switches and routers, supporting hot-swappable deployment. Because it is a passive Twinax assembly, it draws minimal power and introduces very low latency. This makes it a practical choice for in-rack server-to-switch links where fibre optic cabling adds unnecessary cost and complexity.

Specifications

Low-Power 10GbE Connectivity

This passive DAC cable supports 10 Gigabit Ethernet applications through SFP+ ports. It provides a direct electrical connection, so there is no need for optical transceivers. Because it is hot-swappable, you can install or replace it without shutting down your network switch or server. This helps minimise disruption during maintenance or upgrades.

Designed for HPE Compatible Environments

The cable is programmed and tested to work with HPE® brand compatible switches and routers. It complies with MSA industry standards for SFP+ assemblies. However, you should verify compatibility with your specific switch model and firmware version before purchase. Also confirm that your device supports 10G SFP+ DAC cables.

Short-Distance Copper Flexibility

This 3m passive Twinax cable is ideal for point-to-point links within a single rack. It connects servers to top-of-rack switches or links adjacent switches over short runs. Because it uses copper, it avoids the higher cost of fibre optic assemblies for these distances. The black PVC jacket provides basic protection in typical data centre environments.

Stable Performance and Thermal Range

The cable operates reliably in temperatures from 0 °C to 70 °C. It can be stored safely in conditions from -40 °C to 80 °C. These ranges suit most UK data centre and office environments. However, if you plan to deploy in an extreme or uncontrolled environment, confirm that your installation meets these thermal limits.
