PLANET CB-DASFP-0.5M 0.5m SFP+ Direct Attach Copper Cable, 10Gbps, Passive, Black

Data centre technicians connecting top-of-rack switches to servers need a short, reliable, and low-latency link that doesn't break the budget. The PLANET CB-DASFP-0.5M is a 0.5-metre passive Direct Attach Copper (DAC) cable with SFP+ connectors on both ends, delivering 10 Gbps throughput for high-density 10 Gigabit Ethernet, Fibre Channel, and InfiniBand deployments. Its 30 AWG twinaxial construction and 100 Ohm impedance ensure signal integrity over short distances, while the hot-swappable design simplifies installation and maintenance.

Key specifications

• Length: 0.5 m
• Connector 1: SFP+
• Connector 2: SFP+
• Data rate: 10 Gbps
• Type: Passive Direct Attach Copper (DAC)
• Wire gauge: 30 AWG
• Impedance: 100 Ohm
• Power consumption: < 0.1 W
• Operating temperature: 0 to 70 °C
• Compliance: SFF-8431, SFF-8472, RoHS

Why choose it

This cable eliminates the need for separate optical transceivers and fibre, cutting cost and power draw in short-reach connections. Passive design means no active electronics, reducing failure points and heat. The black PVC jacket is durable and flexible for easy routing in crowded racks. With hot-swappable SFP+ ends, you can replace or move links without downtime.

Ideal use cases

• Connecting servers to top-of-rack switches in data centres
• Linking storage arrays in Fibre Channel SANs
• High-performance computing clusters using InfiniBand
• Short-distance 10G Ethernet uplinks between network devices

Good to know

The cable is compliant with SFF-8431 and SFF-8472 MSA specifications, ensuring interoperability with all standard SFP+ ports. It operates reliably in temperatures from 0 to 70 °C and can be stored from -40 to 85 °C. At only 0.5 m, it is ideal for intra-rack connections where longer cables would create clutter and signal loss.
