BlueOptics QDD-400-CU2M-BL InfiniBand fibre optic cable 2 m QSFP-DD Black

The BlueOptics QDD-400-CU2M-BL InfiniBand fibre optic cable is a 2 m male-to-male assembly with QSFP-DD connectors, engineered for high-density network and compute environments. It provides a direct, low-latency link for high-speed data transfer between switches, servers and storage devices where InfiniBand or QSFP-DD interfaces are used. The cable's black jacket and compact connector design support organised cabling in racks and enclosures while maintaining signal integrity for short-reach connections.

Advantages

This cable offers a combination of high throughput and reliable physical connection suitable for InfiniBand QSFP-DD ports. The 2 m length balances reach and signal quality for typical rack-to-rack or within-rack connections. Male-to-male QSFP-DD terminations ensure compatibility with standard QSFP-DD ports and simplify integration into existing network topologies. The construction prioritises robust electrical and optical performance for stable, low-latency links in data centre and high-performance computing setups.

Suitable for

• High-performance computing clusters requiring InfiniBand connectivity
• Interconnects between QSFP-DD enabled switches and servers
• Short-reach rack-to-rack or within-rack fibre connections
• Data centre equipment requiring compact, high-density cabling

Key specifications

• Connector type: QSFP-DD male to QSFP-DD male
• Length: 2 metres
• Application: InfiniBand high-speed interconnects
• Colour: Black jacket
• Design focus: Short-reach, high-density data centre links

How to use

Insert each QSFP-DD connector into corresponding QSFP-DD ports on your networking equipment until the connector latches. Ensure that both ends are fully seated and that port LEDs indicate an active link. Route the cable to avoid excessive bends and mechanical strain; maintain minimum bend radius as specified by your hardware vendor. For troubleshooting, swap ports or replace with a known-good cable to isolate potential port or cable issues.

Recommendations

Use this 2 m QSFP-DD InfiniBand cable for short-reach connections inside racks or between adjacent racks. Keep the cable away from sharp edges and high-traffic pathways, and ensure connectors remain clean and free of dust. Follow equipment vendor guidelines for transceiver and port compatibility when deploying in mixed environments.
