InfiniBand Active Optical Cable CBO QSFP-AOC-2M-CN-BO 2 m QSFP-to-QSFP

InfiniBand Active Optical Cable CBO QSFP-AOC-2M-CN-BO 2 m QSFP-to-QSFP is a 2-metre QSFP-to-QSFP active optical interconnect designed for short-reach, high-throughput links in data centers and high-performance computing clusters. The cable uses optical transmission to deliver low-latency, high-bandwidth connectivity between servers, switches and storage systems while reducing electromagnetic interference and improving signal integrity compared with equivalent copper assemblies.

Advantages

This active optical cable provides consistent high-speed performance over a 2 m link with QSFP form-factor connectors that support standard InfiniBand and compatible QSFP ports. Optical transmission reduces crosstalk and EMI sensitivity, enabling reliable links in dense rack environments. The integrated transceivers eliminate the need for separate modules and simplify installation and cable management. Low insertion loss and optimized signal conditioning support stable operation under typical data center temperatures and workloads.

Suitable for

• High-performance computing clusters requiring low-latency node interconnects
• Data center switch-to-switch and server-to-switch links at short reach
• Storage arrays and SAN connections needing high bandwidth and signal integrity
• Environments where electromagnetic interference from copper cables must be minimized

Key specifications

• Form factor: QSFP-to-QSFP active optical cable
• Length: 2 metres
• Interface: QSFP electrical/optical connector compatibility for InfiniBand and QSFP-capable ports
• Transmission type: Optical (active cable with integrated transceivers)
• Typical use: Short-reach, high-bandwidth data center interconnects
• Latency: Designed for low-latency links suitable for cluster and switch fabrics
• EMI performance: Immune to electromagnetic interference typical of fibre-optic links

How to use

Ensure both endpoints have compatible QSFP ports and that the system firmware or drivers support QSFP active optical cables. With equipment powered down or in accordance with hot-plug guidance from your hardware vendor, align the QSFP connectors with the port guides and insert the cable until it latches. After insertion, verify link status in the host or switch management interface and confirm negotiated speeds and lanes. If required, follow vendor instructions to update firmware or configure port settings for InfiniBand or Ethernet operation.

Recommendations

Handle the cable by the connector housing and avoid tight bends; maintain the manufacturer’s minimum bend radius for optical assemblies. Route the cable to prevent strain on connectors and avoid exposure to sharp edges or pinch points. For reliable operation, monitor link status and environmental conditions, and replace the cable if the connector latches or optical performance degrade.
