InfiniBand/fibre optic cable BlueOptics 571540002-BL 3 m SFP+ Male/Male

The BlueOptics 571540002-BL is a 3 m InfiniBand/fibre optic twinax direct attach cable with SFP+ male-to-male connectors designed for short-reach, high-speed network links. This cable supports 10GBase-CR electrical signalling over a passive twinax copper construction and follows MSA guidelines for SFP+ form factor compatibility. It is intended for linking devices in racks and between adjacent racks where a reliable, low-latency connection is required.

Advantages

This 3 m SFP+ male/male cable provides a cost-efficient option for short-distance 10 Gbps links with low power consumption and minimal latency because it is a passive direct attach cable (DAC). Manufactured to MSA-compliant dimensions and using quality components, it offers broad interoperability with switches, routers and storage systems that support SFP+ passive twinax connections. The cable’s simple passive design results in low failure rates and long operational life.

Suitable for

• Top-of-rack and adjacent-rack connections in data centres
• 10 Gbps links between switches and servers
• Storage area network interconnects supporting 10GBase-CR
• InfiniBand and Fibre Channel short-reach links where SFP+ is supported

Key specifications

• Length: 3 metres
• Connector type: SFP+ male to SFP+ male
• Data rate: up to 10 Gbps (10GBase-CR)
• Cable type: passive twinax copper (DAC), 30 AWG conductor gauge
• Form factor: SFP+ MSA-compliant
• Typical use: short-reach, rack-to-rack or intra-rack links

How to use

Insert each SFP+ connector into the corresponding SFP+ port on the network devices until the latch engages. Ensure both devices support passive SFP+ direct attach twinax cables and the 10GBase-CR signalling standard. Do not force the connector; operate with the equipment powered down or follow your hardware vendor’s hot-plug guidance. Route the cable without sharp bends and avoid excessive tension to preserve signal integrity.

Recommendations

Verify compatibility with your switch, router or storage system before installation. For best results, use this 3 m passive SFP+ DAC in short-reach scenarios such as intra-rack or adjacent-rack connections, keep cable length appropriate for the application, and follow vendor guidance on supported firmware and port settings.
