CBO InfiniBand Active Optical Cable QSFP-AOC-5M-QL-BO 5 m QSFP+ to QSFP+

The CBO InfiniBand Active Optical Cable QSFP-AOC-5M-QL-BO 5 m QSFP+ to QSFP+ is a 5-metre active optical link for high-speed InfiniBand-compatible interconnects between servers, switches and storage devices. This QSFP+ to QSFP+ AOC uses optical signalling and active electronics to deliver low-latency data transfer with improved electromagnetic immunity and longer reach than equivalent copper cables. It is intended for data centre and high-performance computing (HPC) installations where consistent signal integrity and simplified cabling are required.

Advantages

The active optical design reduces susceptibility to electromagnetic interference and provides stable signal integrity over its 5 m length while lowering weight and improving airflow compared with passive copper assemblies. Native QSFP+ connectivity ensures compatibility with InfiniBand QSFP+ ports and supports the physical requirements of high-bandwidth links. As an optical cable, it removes the need for transceiver modules at each end and helps maintain predictable latency for latency-sensitive workloads.

Suitable for

• High-performance computing clusters and node interconnects
• Top-of-rack and end-of-row switch-to-switch interconnects
• Server-to-storage and SAN connectivity in data centres
• Environments requiring reduced electromagnetic interference and improved signal integrity

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 5 metres
• Cable type: Active optical cable (AOC)
• Designed for: InfiniBand-compatible high-speed links
• Performance characteristics: low latency, optical signalling, immunity to electromagnetic interference
• Typical applications: data centre and HPC interconnects

How to use

Install the cable by inserting each QSFP+ end into the corresponding QSFP+ ports on switches, servers or storage devices until the latch engages. Ensure devices are powered down or follow hot-plug guidance from the equipment vendor if applicable. Verify link status on both devices after connection. Route the cable to avoid sharp bends and mechanical strain; maintain the minimum bend radius specified by the equipment manufacturer to preserve optical performance.

Recommendations

For best results, use the AOC in matched QSFP+ ports supporting InfiniBand speeds, avoid kinking or tight bends, and follow your hardware vendor’s guidelines for hot-plugging and cable routing to maintain signal integrity and system reliability.
