CBO InfiniBand Cable BN-QS-QS-CBL-5M-IB-BL 5 m QSFP-to-QSFP blue

CBO InfiniBand Cable BN-QS-QS-CBL-5M-IB-BL is a 5-metre QSFP-to-QSFP direct-attach cable in blue, engineered for short-reach high-speed InfiniBand links. The cable connects QSFP ports on switches, network adapters and servers, providing a stable physical layer for low-latency data transfer in dense environments. It is built to meet the needs of data centres and high-performance computing clusters that require reliable, low-latency interconnects.

Advantages

This QSFP-to-QSFP cable offers a fixed, low-latency electrical connection with predictable signal integrity and reduced power overhead compared with optical transceivers. The 5 m length balances reach and signal quality for typical rack-to-rack or aisle cabling scenarios. The blue jacket improves visual identification in cabling bundles and simplifies management. The direct-attach design reduces component count and simplifies installation and replacement operations.

Suitable for

• Short-reach high-bandwidth links between switches and top-of-rack equipment
• Server-to-switch connections in compute clusters and HPC environments
• Network adapter interconnects where QSFP ports are available
• Environments requiring consistent low-latency and high throughput

Key specifications

• Connector type: QSFP (QSFP-to-QSFP direct attach)
• Cable length: 5 metres
• Cable colour: blue for easy identification
• Intended use: short-reach InfiniBand interconnects
• Design: direct-attach fixed cable suitable for high-density racks

How to use

Insert each QSFP connector into compatible QSFP ports on the devices to be connected, ensuring alignment of the latch or guide features. Route the cable to avoid sharp bends and maintain proper bend radius to preserve signal integrity. Verify link status on connected devices and, where applicable, configure port settings for the intended InfiniBand link speed and topology. For replacement, power down or follow vendor hot-swap procedures as required by your hardware before unplugging and re-plugging the cable.

Usage recommendations

For optimal performance, use the cable within rack or aisle distances up to 5 metres, avoid tight cable bundles that cause excessive heat, and confirm compatibility with your switches and host adapters’ supported QSFP electrical specifications.
