BlueOptics 40G-QSFP-C-0501 InfiniBand optický kábel 5 m čierny

The BlueOptics 40G-QSFP-C-0501 InfiniBand fibre optic cable 5 m Black is a 5-metre passive cable engineered for high-speed data connectivity in data centres and high-performance computing clusters. With QSFP connectors on both ends and a male-to-male configuration, this cable supports 40 Gbit/s links over InfiniBand-compatible ports, providing a compact and reliable interconnect between switches, servers and storage modules. The black outer jacket offers standard protection for rack and chassis environments while the cable’s design focuses on signal integrity and consistent throughput.

Advantages

This 5 m QSFP-to-QSFP cable delivers low-latency, high-bandwidth connections suitable for dense networking setups. The male/male QSFP terminations ensure straightforward plug-and-play installation without additional transceivers. Its fixed-length design reduces potential points of failure compared with modular assemblies and simplifies cable management in racks. The cable’s passive construction offers predictable performance for short-reach links and is compatible with a wide range of InfiniBand and QSFP-enabled equipment.

Suitable for

• Interconnecting QSFP ports on switches and routers within a rack
• Direct server-to-switch links in data centres and HPC clusters
• Short-reach connections between storage arrays and compute nodes
• Cable replacement or consolidation in dense rack deployments

Key specifications

• Connector type: QSFP male to QSFP male
• Supported data rate: up to 40 Gbit/s
• Length: 5 metres
• Application: InfiniBand high-speed interconnects
• Colour: Black outer jacket
• Construction: Passive fibre optic cable for short-reach links

How to use

Install the cable by aligning each QSFP male connector with the corresponding QSFP port on your equipment and insert until it seats securely. Ensure devices are powered according to manufacturer guidelines and that ports are configured for InfiniBand operation at the intended data rate. Route the 5 m cable to avoid tight bends and mechanical strain; maintain recommended bend radii to preserve optical performance. For multi-rack deployments, verify link negotiation and monitor error counters after installation to confirm signal integrity.

Recommendations

Use this cable for short-reach, high-bandwidth links within racks or adjacent racks; avoid using it for long-haul connections. Store and route the cable so that bend radius and tensile limits are not exceeded, and inspect connectors before insertion to prevent contamination. Verify compatibility with your QSFP ports and firmware to ensure reliable operation at 40 Gbit/s.
