BlueOptics 40GB-F20-QSFP-BO InfiniBand fibre optic cable 20 m Male/Male

The BlueOptics 40GB-F20-QSFP-BO InfiniBand fibre optic cable 20 m Male/Male is a high-speed duplex cable designed for short- to medium-reach links in data centres and high-performance computing environments. With QSFP-compatible connectors and a 20 metre length, this fibre cable supports reliable 40 Gbit/s InfiniBand links and minimizes signal loss for stable data transmission between switches, servers and storage systems.

Advantages

This fibre optic cable offers low insertion loss and consistent optical performance for InfiniBand environments. The QSFP Male/Male connector configuration enables direct connections between compatible QSFP ports without additional adapters. A 20 metre length provides flexibility for rack-to-rack and chassis-to-chassis cabling while maintaining signal integrity for demanding applications.

Suitable for

• Interconnecting QSFP ports on switches and routers in data centres
• Connecting servers and storage appliances in high-performance computing (HPC) clusters
• Short- to medium-reach backbone links within server rooms and wiring closets
• Environments requiring low-latency, high-throughput InfiniBand connections

Key specifications

• Data rate: 40 Gbit/s compatible with InfiniBand QSFP interfaces
• Length: 20 metres
• Connector type: QSFP Male to QSFP Male
• Cable type: Duplex fibre optic suitable for InfiniBand signalling
• Optimised for low insertion loss and minimal signal degradation over the specified length

How to use

Route the BlueOptics 20 m QSFP fibre cable between QSFP ports on devices that support InfiniBand or compatible 40 Gbit/s interfaces. Ensure connectors are clean and free of dust before insertion to prevent optical signal loss. Gently insert QSFP connectors into the corresponding ports until they click or seat properly, and avoid sharp bends or strain on the cable to preserve optical performance. Verify link status on connected devices and perform any required port configuration for InfiniBand operation.

Recommendations

Store and handle the cable in a clean environment, use appropriate fibre cleaning tools for connector endfaces, maintain bend radii above the cable's minimum specification, and avoid kinking or excessive tensile force to ensure consistent 40 Gbit/s performance.
