BlueOptics 40GB-F30-QSFP-BO InfiniBand Fibre Optic Cable 30 m

The BlueOptics 40GB-F30-QSFP-BO InfiniBand fibre optic cable is a 30 m multimode link engineered for high-speed data transmission in demanding network environments. With QSFP connectors on both ends, this cable supports 40 Gbps class InfiniBand connections and is suitable for interconnects between switches, servers, and storage systems in data centers and HPC clusters. The construction minimizes insertion loss and preserves signal integrity over the full 30-m length, offering stable performance for latency-sensitive applications.

Advantages

This 30 m InfiniBand fibre cable provides consistent 40 Gbps throughput with low attenuation and reliable mechanical connector fit. The use of QSFP-compatible terminations ensures broad compatibility with equipment that accepts quad small form-factor pluggable interfaces. Designed for rack-to-rack and row-to-row connections, the cable combines flexible jacket materials for easy routing with robust internal fibre alignment to reduce bit error rates and maintain link stability under continuous operation.

Suitable for

• Data centre switch-to-switch and switch-to-server connections
• High-performance computing (HPC) cluster interconnects
• Storage area networks and SAN aggregation links
• Low-latency trading platforms and compute-intensive workloads

Key specifications

• Cable length: 30 metres
• Connector type: QSFP at both ends
• Supported protocol class: 40 Gbps InfiniBand
• Fibre type: multimode fibre suitable for short- to medium-range connections
• Jacket: flexible, routing-friendly protective sheath

How to use

Route the BlueOptics 40GB-F30-QSFP-BO cable between QSFP ports on the devices to be connected, avoiding sharp bends and excessive torsion. Ensure QSFP ports are powered down or follow hot-plug guidelines from your equipment manufacturer when inserting or removing connectors. Verify link status and error counters after installation and configure the devices according to your InfiniBand switching or host channel adapter settings to establish full 40 Gbps links.

Recommendations

Store and handle the cable in a clean environment to prevent contamination of connector endfaces; use appropriate dust caps when connectors are not in use. For best results in data centre layouts, plan cable routes to minimize bend radii and avoid tight cable bundles that could affect cooling or serviceability.
