InfiniBand/fibre optic cable BlueOptics 0231A0AL-3C-BL 1 m SFP+ SFP+ DAC Black

The BlueOptics 0231A0AL-3C-BL is a 1 m direct attach cable (DAC) with SFP+ to SFP+ connectors designed for 10G links in rack and adjacent-rack environments. It is a passive twinax copper solution compatible with standard SFP+ ports and supports Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand applications up to 10 Gbit/s over a 1 meter distance. The cable is intended for short-range, high-speed connections between switches, routers, storage systems and other data centre hardware that support SFP+ passive DACs.

Advantages

This passive DAC offers low power consumption and low latency compared with active optical transceivers, making it suitable for dense rack installations where short electrical connections are required. Manufactured to industry MSA-compliant dimensions with high-quality twinax conductors (30 AWG), it provides stable 10G performance for supported protocols. The passive design reduces component complexity and potential failure points, while compatibility testing ensures proper operation with major hardware platforms that accept SFP+ direct attach cables.

Suitable for

• Short-range 10G server-to-switch or switch-to-switch connections within racks
• Direct attach links between adjacent racks in data centres
• High-throughput storage connectivity and SAN links using FCoE or Fibre Channel
• InfiniBand or other 10G networking applications where SFP+ passive DACs are supported

Key specifications

• Connector type: SFP+ to SFP+ (male/male)
• Cable type: Passive twinax copper (DAC)
• Length: 1 m
• Data rate: Up to 10 Gbit/s
• Wire gauge: 30 AWG
• Applications supported: Ethernet, FCoE, Fibre Channel, InfiniBand
• Compliance: MSA-compliant mechanical and electrical interface

How to use

Connect one SFP+ plug into the SFP+ port of the first device and the other plug into the SFP+ port of the second device. Ensure both devices support passive SFP+ direct attach twinax cables and that the configured link settings (speed and protocol) match the intended use. No external power or transceiver modules are required for the passive DAC; link negotiation and protocol handling are performed by the connected hardware. Verify link status and error counters in the device management interface after installation.

Recommendations

Use this 1 m passive SFP+ DAC for short-distance connections inside racks or between adjacent racks to achieve cost-effective 10G interconnects. Avoid tight bends and excessive mechanical stress on the cable and connectors; maintain the manufacturer’s recommended bend radius. Confirm hardware compatibility with your switch or server vendor and test the link after installation to ensure stable operation.
