BlueOptics 0231A0AM-BL InfiniBand fibre optic cable 3 m SFP+ SFP+ DAC Black

The BlueOptics 0231A0AM-BL InfiniBand fibre optic cable is a 3 m SFP+ to SFP+ direct attach cable (DAC) designed for short-distance, high-speed connections in rack and adjacent-rack environments. It features male SFP+ connectors on both ends and supports 10G data rates over a passive twinax connection. The cable is MSA-compliant and intended for use with network switches, routers, storage systems and other hardware that support SFP+ DAC links.

Advantages

This passive 3 m DAC offers low latency and low power consumption compared with active transceiver solutions, making it suitable for dense data center deployments. Constructed from high-quality components and manufactured to MSA standards, the cable provides consistent signal integrity for Ethernet, FCoE, Fibre Channel and InfiniBand applications up to 10 Gbit/s. The simple, passive design reduces points of failure and supports a long service life under normal operating conditions.

Suitable for

• Connecting SFP+ ports between switches and servers within the same rack or adjacent racks
• 10G Ethernet, FCoE, Fibre Channel and InfiniBand short-reach links
• Data center top-of-rack and storage area network (SAN) interconnects
• Upgrading existing infrastructure to SFP+ direct attach cabling for cost-effective links

Key specifications

• Cable length: 3 metres
• Connector type: SFP+ male to SFP+ male
• Data rate: up to 10 Gbit/s
• Cable type: passive twinax (direct attach cable)
• Wire gauge: 30 AWG
• Compliance: MSA-compliant
• Colour: black

How to use

Verify that both endpoints support passive SFP+ DACs and that the network devices’ firmware or software does not restrict the use of third-party DACs. Align each SFP+ connector with the device port and insert until the latch engages. For removal, depress the latch and pull the connector straight out. Use cable management within racks to avoid sharp bends; maintain the specified minimum bend radius and avoid tension on the cable to preserve signal integrity.

Recommendations

For best results, use this 3 m DAC in short-reach links inside racks or between adjacent racks where passive twinax is supported. Ensure regular inspection for physical damage and follow vendor guidance for compatibility with specific switch or storage models.
