InfiniBand/fibre optic cable BlueOptics 470-ABIT-BL 0.5 m QSFP Male/Male

The BlueOptics 470-ABIT-BL is a 0.5 m InfiniBand/fibre optic cable with QSFP Male to QSFP Male connectors designed for short-range, high-speed links in data centre and high-performance computing environments. It supports 40GBase-CR4 electrical transmissions over a 0.5 metre direct-attach twinax copper construction and is compatible with major hardware platforms that accept QSFP-to-QSFP direct attach cables.

Advantages

This 0.5 m cable offers low latency and low power consumption typical of passive direct attach twinax solutions. Manufactured according to MSA-compliant mechanical and electrical guidelines and built from high-quality components, it provides reliable connectivity for switches, routers and storage systems. The short length and QSFP Male/Male design simplify rack-to-rack or within-rack connections while maintaining 40 Gbit/s throughput where supported by the host hardware.

Suitable for

• Short-distance rack and adjacent-rack interconnects in data centres
• 40 Gbit/s Ethernet, Fibre Channel over Ethernet (FCoE) and InfiniBand applications where host hardware supports passive DAC
• High-performance computing clusters and storage system interlinks
• Switch-to-switch and switch-to-server QSFP connections within the same rack

Key specifications

• Length: 0.5 metre
• Connector type: QSFP Male to QSFP Male
• Transmission format: 40GBase-CR4 (passive direct attach twinax copper)
• Suitable data rate: up to 40 Gbit/s over the specified length
• Construction: passive twinax copper (30 AWG type cable)

How to use

Ensure both devices support passive QSFP-to-QSFP direct attach cables and the required 40GBase-CR4 protocol. With equipment powered down or following live-insertion guidelines from your hardware vendor, insert each QSFP connector firmly into the corresponding QSFP port until the latch engages. Verify link status and negotiate speed in the host operating system or switch management interface. For best results, use this 0.5 m cable for direct, short links inside racks or between adjacent racks as specified by your network design.

Recommendations

Avoid routing the cable near sources of strong electromagnetic interference and do not exceed the recommended bend radius. Use in environments and with hardware that explicitly support passive QSFP DACs to ensure proper operation and to prevent damage. Follow vendor-specific installation and handling instructions for QSFP modules.
