BlueOptics 40G-QSFP-QSFP-C-0301 InfiniBand fibre optic cable 3 m Male/Male

The BlueOptics 40G-QSFP-QSFP-C-0301 InfiniBand fibre optic cable 3 m Male/Male is a high-speed, short-reach cable designed for InfiniBand and QSFP-based networking equipment. With a 3 metre jacketed length and QSFP-to-QSFP male connectors at both ends, this cable supports 40 Gigabit data rates and is intended for rack-to-rack, switch-to-switch or switch-to-HPC node connections in data centre and high-performance computing environments. The cable construction focuses on signal integrity and connector reliability to maintain stable links under continuous operation.

Advantages

The cable provides 40G data throughput compatible with QSFP ports and InfiniBand architectures, enabling low-latency high-bandwidth connections. Its male-to-male QSFP connectors ensure direct interfacing with QSFP transceivers and ports without adaptors. The 3 m length allows flexible placement within racks while minimising excess cabling; the design emphasises durability and stable optical performance for sustained network loads.

Suitable for

• Connecting QSFP-enabled switches and routers within data centre racks
• Linking high-performance computing nodes and InfiniBand switches
• Short-reach uplinks and cross-connects where 3 m cable length is appropriate
• Environments requiring 40 Gigabit links with QSFP interfaces

Key specifications

• Cable type: multi-mode fibre suitable for InfiniBand QSFP connections
• Connector type: QSFP male to QSFP male
• Data rate: supports 40 Gigabit transmission
• Length: 3 metres
• Application: short-reach rack and in-cabinet connections
• Construction: jacketed fibre assembly designed for cable management and connector protection

How to use

Ensure both devices have QSFP ports compatible with 40G optical links before connecting. Handle the cable by the connector housings and avoid bending the fibre beyond the specified minimum bend radius to prevent signal degradation. Insert the QSFP connectors until they latch securely into place, verifying link status on the connected equipment. For removal, release the connector latch and pull straight out to avoid stressing the fibre or connector.

Recommendations

Install the cable in managed rack pathways or containment to prevent physical damage and minimise bend stress. Keep dust caps on unused connectors until installation and verify optical link parameters after connection. Use for short-reach 40G QSFP links in data centres and HPC setups where a reliable InfiniBand connection is required.
