BlueOptics 40GB-F05-QSFP-BO InfiniBand fibre optic cable 5 m QSFP Male/Male

The BlueOptics 40GB-F05-QSFP-BO InfiniBand fibre optic cable 5 m QSFP Male/Male is a 5-metre multimode fibre link engineered for high-throughput, low-latency connections in professional networking environments. With QSFP male connectors on both ends, this cable supports InfiniBand connectivity and 40 Gbps class data transfer between compatible switches, host adapters and high-performance computing nodes. Its sheath and connector construction are designed for frequent handling in racks and data centre pathways while maintaining signal integrity over the specified length.

Advantages

This fibre optic cable provides stable 40 Gbps-capable links with low insertion loss and predictable performance across the 5 m span. QSFP male-to-male termination ensures straightforward plug-and-play installation in QSFP ports without additional adapters. The cable’s design balances flexibility and ruggedness for routing in dense rack environments and reduces crosstalk and electromagnetic interference inherent to copper alternatives.

Suitable for

• Interconnect between QSFP-equipped switches and routers
• Connections to InfiniBand host channel adapters in compute clusters
• Patch runs within data centre racks and top-of-rack installations
• High-speed storage networking and server uplinks

Key specifications

• Connector type: QSFP male on both ends
• Length: 5 metres
• Interface standard: InfiniBand/40 G class connectivity
• Transmission medium: Fibre optic (multimode)
• Typical use: Short-reach high-bandwidth links for racks and clusters

How to use

Install the cable by aligning and inserting each QSFP male connector into the corresponding QSFP port until it seats securely. Route the cable along existing cable management paths to avoid sharp bends and ensure bend radius is not exceeded. Verify link status on connected devices and confirm negotiated speeds and link integrity via switch or host interface diagnostics. For best results, keep the connectors clean and capped when not in use.

Recommendations

Avoid tight bends and excessive pulling force; maintain specified bend radius and use cable ties or Velcro straps for secure but non-compressive routing. Regularly inspect connector end-faces and clean with appropriate fibre cleaning tools before mating. Use this 5 m QSFP cable for short-reach high-bandwidth links inside racks or between adjacent equipment to ensure optimal 40 G class performance.
