Active Optical InfiniBand Cable CBO QSFP-AOC-30M-PT-BO 30 m QSFP to QSFP

The Active Optical InfiniBand Cable CBO QSFP-AOC-30M-PT-BO is a 30-meter duplex QSFP-to-QSFP active optical cable designed for high-performance computing and data center interconnects. It provides a direct optical link between QSFP ports on switches, adapters and servers, offering low latency and high bandwidth over a longer distance than copper DACs. The cable's active optical design reduces electromagnetic interference and simplifies rack-to-rack cabling while maintaining signal integrity for demanding InfiniBand environments.

Advantages

This active optical cable combines the convenience of a fixed-length assembly with the signal quality of optical transmission, enabling stable long-reach connections without transceiver modules at each end. It reduces heat and power consumption compared with equivalent active electrical solutions and minimizes crosstalk and EMI in dense rack configurations. The QSFP form-factor on both ends supports high-density installations and straightforward plug-and-play deployment.

Suitable for

• Rack-to-rack links in data centers
• High-performance computing clusters and node interconnects
• Connections between QSFP-enabled switches, NICs and host adapters
• Environments requiring low-latency, high-bandwidth links over medium distances

Key specifications

• Length: 30 meters of active optical cable
• Connector type: QSFP on both ends (QSFP-to-QSFP)
• Transmission medium: active optical fiber
• Designed for InfiniBand high-speed protocols and compatible QSFP interfaces
• Low-latency, high-bandwidth performance suitable for data center and HPC use
• Reduced electromagnetic interference compared to copper alternatives

How to use

Install the cable by plugging each QSFP connector into the corresponding QSFP port on networking equipment or servers while the devices are powered down or following the vendor's hot-plug guidance. Ensure connectors are clean and free of debris before insertion to maintain optical performance. Route the cable to avoid excessive bending or pressure; observe minimum bend radius recommendations for optical assemblies. Verify link status through device management interfaces and perform a basic link test to confirm full bandwidth and low-latency operation.

Recommendations

Store unused cable lengths coiled without tight bends and protect QSFP connectors with dust caps when not connected. Match the cable with QSFP-capable ports that support the intended InfiniBand speed grade, and consult equipment compatibility lists if precise interoperability details are required. Regularly inspect connector endfaces and clean with approved fiber-optic cleaning tools to preserve signal quality.
