## Summary description

Passive copper InfiniBand cable CBO AT-QSFP5CU-BL, 5 meters long, with QSFP connectors at both ends. Designed for short-range high-throughput interconnections between network switches, adapters or storage nodes that support QSFP interfaces. Provides a simple, low-latency link for rack or cabinet setups where fibre is not required.

## Long description

The CBO InfiniBand passive copper cable AT-QSFP5CU-BL is a 5 m QSFP-to-QSFP cable in blue designed for short-range, high-throughput connections between network switches, adapters and storage nodes that support QSFP interfaces. It provides a low-latency direct attach solution for dense rack or cabinet environments where fibre optics are unnecessary. The passive copper design delivers reliable electrical performance for InfiniBand links while keeping power consumption and complexity low.
Advantages
This passive copper cable offers a straightforward installation with QSFP connectors on both ends and requires no external power or active electronics. It reduces latency compared with optical transceivers and fibers for short distances and provides stable signal integrity for high-speed InfiniBand links. The fixed 5 m length and durable blue jacket make cable management and identification in racks and data center cabinets easier.
Suitable for
 Short-range interconnects within racks and between adjacent cabinets
 High-throughput InfiniBand fabrics linking switches, adapters and storage nodes
 Low-latency connections for HPC clusters and compute nodes
 Environments where a simple, cost-effective copper direct attach solution is preferred over fibre
Key specifications
 Cable type: Passive copper direct attach
 Connector type: QSFP to QSFP
 Length: 5 meters
 Color: Blue
 Use case: Short-range, high-speed InfiniBand interconnects
How to use
Connect each QSFP connector to compatible QSFP ports on your switches, adapters or storage devices. Ensure ports support passive copper direct attach cables and that link settings (speed, lanes) match on both ends. Route the cable neatly within the rack or cabinet to avoid sharp bends and mechanical stress. No additional configuration is normally required beyond verifying link status and port negotiation on connected devices.
Usage recommendations
Handle the cable by the connector housings and avoid bending the cable sharply. Use proper cable routing and labeling in cabinets to maintain airflow and simplify maintenance. Verify compatibility with your InfiniBand hardware and firmware versions before deployment, and test link performance after installation to confirm expected throughput and latency.
