BlueOptics 00D5810-BL InfiniBand/fibre optic cable 5 m QSFP Male/Male

The BlueOptics 00D5810-BL InfiniBand/fibre optic cable 5 m QSFP Male/Male is a 5‑metre direct attach twinax/InfiniBand solution with QSFP connectors on both ends. Designed for short-reach, high-speed links in racks and between adjacent racks, it supports 40G data rates and is suitable for Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand environments. The cable implements a passive 40GBase-CR4 twinax copper design with 30 AWG conductors and complies with MSA connector specifications for compatibility with major network hardware that accepts QSFP direct attach assemblies.

Advantages

This QSFP-to-QSFP direct attach cable provides a low-latency, low-power connection for short-distance high-bandwidth links. As a passive 40GBase-CR4 twinax cable, it requires no active electronics in the cable itself and offers simple plug-and-play deployment. The construction follows MSA guidelines and uses high-quality materials suitable for professional rack environments, delivering stable signal transmission for typical data centre and networking equipment that supports 40G direct attach connections.

Suitable for

• Interconnects between switches and routers within the same rack or adjacent racks
• High-speed links for storage systems and SAN uplinks (FCoE/Fibre Channel)
• InfiniBand and HPC cluster node connections requiring 40G throughput

Key specifications

• Length: 5 metres
• Connector type: QSFP male to QSFP male
• Data rate support: up to 40 Gbps over 5 m
• Cable type: passive twinax copper (DAC), 30 AWG conductors
• Standards: 40GBase-CR4, MSA-compliant QSFP form factor

How to use

Ensure both devices support passive QSFP direct attach twinax cables and 40GBase-CR4 operation. Power down equipment or follow hot-plug procedures recommended by the hardware vendor before inserting the QSFP plugs. Align each QSFP connector with the port and press until the latch engages. Verify link activity and speed on the connected devices through their management interfaces. To disconnect, release the QSFP latch and pull straight out to avoid port damage.

Recommendations

For reliable performance, use this cable for short-reach connections within racks or between adjacent racks only. Keep cable runs free from sharp bends and avoid exceeding the recommended minimum bend radius. Confirm device firmware and port settings support passive DAC operation at 40G and test links after installation to validate compatibility.
