IBM 00AY765 - cable Direct Attach de cobre Twinax pasivo SFP+ 10G compatible (DAC), 2m (7ft)

This 10G SFP+ Direct Attach Cable (DAC) delivers a cost-effective, low-latency 10 Gigabit Ethernet connection over short distances. Its passive twinax copper design provides ultra-low power consumption and minimal signal degradation, making it ideal for high-density data center and enterprise network deployments where reliability and efficiency are paramount.

Advantages

The passive copper construction eliminates the need for optical transceivers, reducing both cost and power draw to less than 0.1W per link. It ensures deterministic latency and excellent signal integrity over 2 meters, while the hot-swappable SFP+ connectors allow for quick installation and maintenance without network downtime.

Suitable for

• Top-of-rack (ToR) switch-to-server connections in data centers
• High-performance computing (HPC) clusters requiring low-latency interconnects
• Enterprise network aggregation links between switches and storage systems
• Fibre Channel over Ethernet (FCoE) and InfiniBand applications

Key specifications

• Data rate: 10 Gbps
• Cable type: Passive Direct Attach Cable (DAC)
• Connectors: SFP+ to SFP+
• Cable material: Copper twinax
• Length: 2 meters (7 feet)
• Impedance: 100 Ohm
• Operating temperature: 0°C to 70°C
• Compliance: SFF-8431, SFF-8472, RoHS

Recommendations

For short-reach 10G links where power budget and cost are critical, this passive DAC is the optimal choice. Ensure both connected devices have SFP+ ports and support passive copper cabling. Avoid excessive bending to maintain signal integrity.
