Active Optical InfiniBand Cable CBO QSFP-AOC-2M-SW-BO 2 m, QSFP+, active optical

CBO QSFP-AOC-2M-SW-BO is a 2 m active optical InfiniBand cable with QSFP+ connectivity designed for short-reach, high-speed links between switches, servers and storage devices. The cable provides optical transmission over a two metre reach, offering low latency and high bandwidth suitable for data centre interconnects and high-performance computing clusters that require compact, reliable optical cabling.

Advantages

The active optical design reduces electromagnetic interference and heat generation compared with copper alternatives while maintaining signal integrity over the 2 m span. QSFP+ connectivity supports aggregated high-speed lanes and simplifies installation in dense rack environments. The cable's compact form factor and vendor-compatible QSFP+ plug allow straightforward insertion into standard ports, enabling predictable performance for latency-sensitive applications.

Suitable for

• Short-reach links between top-of-rack and leaf switches
• Server-to-switch and storage-to-switch connections in data centres
• High-performance computing (HPC) clusters and InfiniBand fabrics
• Environments where reduced EMI and compact cabling are required

Key specifications

• Connector type: QSFP+ (Quad Small Form-factor Pluggable)
• Cable type: Active optical cable (AOC)
• Length: 2 metres
• Transmission medium: Multimode optical link with active transceivers
• Application: Short-reach, high-bandwidth interconnects for InfiniBand environments
• Latency: Low-latency optical transmission suitable for HPC and storage networks
• Form factor: Compact, hot-pluggable QSFP+ assembly for dense rack deployments

How to use

Insert each QSFP+ connector into the corresponding QSFP+ port on the network devices until the connector latches. Ensure devices are powered and configured for the intended InfiniBand link speed and lane aggregation before initiating traffic. Route the 2 m cable to avoid tight bends and excessive tension; the active optical cable requires gentle handling similar to other fibre assemblies. For interoperable operation, confirm the host and switch support QSFP+ active optical modules and verify link status LEDs after connection.

Recommendations

For best results, use the cable within the specified 2 m reach and avoid exposure to strong bending radii or mechanical stress. Maintain clean connector interfaces and follow data centre cable management practices to preserve signal quality and ensure consistent low-latency operation.
