InfiniBand/fibre optic cable BlueOptics CAB-DAC15M-SFPP-DEC02-BL 2 m SFP+ Male/Male

The BlueOptics CAB-DAC15M-SFPP-DEC02-BL is a 2 m direct attach cable with SFP+ male connectors at both ends, designed for short-range high-speed links in racks and adjacent rack rows. This passive twinax copper cable implements the 10GBase-CR transmission profile and is suitable for InfiniBand and SFP+ fibre optic ports where a direct attach SFP+ to SFP+ connection is supported. The cable is intended for connecting switches, routers, storage systems and other hardware platforms that accept SFP+ direct attach copper assemblies.

Advantages

The cable provides a compact, low-power connection for 10 Gbps links over a 2 m distance without active components, which reduces latency and power consumption. Constructed to industry MSA guidelines for SFP+ direct attach assemblies, it offers predictable electrical performance for short-distance data center interconnects. Its passive twinax design and standardized SFP+ male/male interfaces make it a cost-effective and low-maintenance option for densely populated rack environments.

Suitable for

• 10 Gbps links between switches and routers in racks
• Storage system connections supporting SFP+ DAC
• Short-distance InfiniBand and Ethernet interconnects (up to 2 m)
• Server-to-switch uplinks in data center rows

Key specifications

• Length: 2 meters
• Connector type: SFP+ male to SFP+ male
• Transmission profile: 10GBase-CR (10 Gbps passive DAC)
• Cable type: passive twinax copper (30 AWG)
• Application protocols: Ethernet, FCoE, Fibre Channel and InfiniBand at supported rates

How to use

Insert each SFP+ connector into the corresponding SFP+ port on compatible devices until the latch engages. Ensure both devices support passive SFP+ direct attach cables and the configured transmission protocol (for example 10GBase-CR). Route the 2 m cable to avoid sharp bends and mechanical strain; maintain standard bend radii and secure the cable in the rack to prevent tension on the connectors. Verify link status on connected devices after installation.

Recommendations

Use this 2 m passive SFP+ DAC for short interconnects inside racks or between adjacent racks where 10 Gbps passive twinax is supported. Avoid exceeding recommended bend radii and do not expose the cable to excessive mechanical stress or fluids. For links beyond 2 m or when active signal conditioning is required, choose qualified transceivers with fiber or active optical cables.
