Cable de fibra óptica InfiniBand SFP+ BlueOptics SP-CABLE-ADASFP+3M-BL 3 m conector macho/conector macho

The BlueOptics SP-CABLE-ADASFP+3M-BL is a 3-meter Direct Attach Cable (DAC) with SFP+ male-to-male connectors designed for short-distance high-speed connections in racks and adjacent rack rows. This passive twinax copper cable supports 10GBase-CR electrical signaling over a 3 m length and is suitable for InfiniBand, Ethernet and Fibre Channel topologies where SFP+ ports are used. The cable is MSA-compliant and intended for use with hardware platforms that support SFP+ passive DACs, enabling reliable links between switches, routers, storage systems and servers in data centers and high-performance computing environments.

Advantages

The cable provides low-latency, low-power passive connectivity with a simple plug-and-play design, eliminating the need for separate transceivers. Its 30 AWG twinax conductors and SFP+ to SFP+ connectors deliver consistent 10 Gbps performance across the specified 3 m distance. Being compliant with industry mechanical and electrical specifications ensures wide compatibility with major vendor hardware that accepts SFP+ passive direct attach solutions, while the copper construction avoids the need for optical transceivers for short runs.

Suitable for

• Short-distance 10 Gbps links inside racks and between adjacent racks
• Connecting SFP+ ports on switches, routers, servers and storage arrays
• InfiniBand, Ethernet (10GBase-CR) and Fibre Channel environments that accept passive SFP+ DACs
• Data center top-of-rack and server-to-switch cabling

Key specifications

• Connector type: SFP+ male to SFP+ male
• Length: 3 meters
• Transmission medium: passive twinax copper
• Wire gauge: 30 AWG
• Maximum supported data rate: up to 10 Gbps over specified distance
• Standards: compatible with 10GBase-CR electrical signaling and MSA SFP+ mechanical/electrical form factor

How to use

Confirm that both devices support passive SFP+ direct attach cables and that the SFP+ ports are enabled. Power down or follow hot-swap procedures recommended by your hardware vendor, insert the SFP+ connector into each device until the retention latch engages, and verify link lights or management interfaces report a 10 Gbps connection. No additional transceivers or fiber patching are required; the copper twinax cable provides the complete physical connection for supported protocols.

Recommendations

Use this 3 m passive DAC for short, fixed connections inside racks or between adjacent racks where 10 Gbps performance is required. Avoid tight bends and excessive strain on the cable; maintain the manufacturer’s minimum bend radius and secure cable routing to prevent connector stress. If hardware vendor firmware enforces cable validation, check compatibility notes or request a test sample before large deployments.
