InfiniBand/fibre optic cable BlueOptics AA1404030-E6-EN-BL 2 m QSFP Male/Male

The BlueOptics AA1404030-E6-EN-BL is a 2 m InfiniBand/fibre optic cable with QSFP male connectors on both ends. Designed for short-reach, high-speed links in data centers and high-performance computing environments, this cable supports 40G data rates when used with compatible QSFP ports and hardware that accept direct attach or InfiniBand QSFP connections. The male-to-male QSFP configuration offers a straightforward connection between switches, routers, servers and storage systems that officially support QSFP-based 40G links.

Advantages

This 2 m cable provides a compact, low-latency physical connection for short-distance high-bandwidth interconnects. As a QSFP-to-QSFP assembly, it is suitable for rack-to-rack or intra-rack connections where 40G throughput and minimal power consumption are required. The cable is manufactured to MSA-compatible physical specifications and uses industry-standard connector form factors to ensure interoperability with major vendor hardware that supports QSFP direct attach or InfiniBand interfaces.

Suitable for

• High-density switch-to-switch connections in racks and adjacent racks
• Server-to-switch links in data center top-of-rack and end-of-row layouts
• Short-reach InfiniBand connections in HPC clusters
• Storage array or appliance interconnects that accept QSFP direct attach

Key specifications

• Connector type: QSFP male to QSFP male
• Length: 2 meters
• Supported link speed: up to 40 Gbit/s (with compatible hardware)
• Cable type: direct attach twinax / short-reach InfiniBand/fibre optic assembly and passive electrical transmission where applicable
• Conforms to MSA-compatible QSFP physical form factor

How to use

Install by inserting each QSFP male connector into the corresponding QSFP port on the devices to be connected, ensuring the connectors latch and the port indicators confirm link status. Verify that both endpoints support 40G QSFP or InfiniBand operation and that firmware or software settings allow passive direct-attach cable usage if applicable. For initial setup, confirm link negotiation and test throughput with your monitoring tools to ensure expected performance.

Recommendations

Use this cable for short-distance interconnects inside racks or between adjacent racks. Avoid routing the cable along heat sources or sharp bends; maintain minimum bend radius as specified by the hardware vendor. Ensure your equipment explicitly supports passive QSFP direct attach or the InfiniBand protocol at 40G before deployment.
