Cabo SFP+ Direct Attach passivo BlueLAN DAC10G-50CM-BL 10GBASE-CR, 0,5 m

This 0.5-metre passive SFP+ direct attach cable delivers a full 10 Gbps link over twinax copper, making it a compact and power-efficient choice for short-reach connections in dense rack environments. The BlueLAN DAC10G-50CM-BL is built for ZyXEL compatibility and plugs directly into any SFP+ port without the cost or latency of optical transceivers.

Advantages

Passive twinax design consumes less than 0.1 W, helping to keep overall switch power budgets low. The 30 AWG conductors and PVC jacket provide a durable yet flexible cable that is easy to route in tight spaces. Hot-swappable SFP+ connectors allow quick installation or replacement without downtime, while the 0.5 m length minimises clutter between adjacent ports.

Suitable for

• Linking servers to top-of-rack switches in data centres
• Connecting storage arrays and network appliances over short distances
• Upgrading existing ZyXEL or SFP+ compliant equipment to 10 Gigabit Ethernet
• High-density rack environments where power and airflow are constrained
