Active Optical InfiniBand Cable CBO QSFP-AOC-2M-BC-BO 2 m, QSFP+ to QSFP+

CBO QSFP-AOC-2M-BC-BO is a 2 meter active optical InfiniBand cable with QSFP+ to QSFP+ connectors designed for low-latency, high-bandwidth short-range links. The cable uses active optical technology to maintain signal integrity over a 2 m span while reducing electromagnetic interference and heat generation compared with copper alternatives. It is intended for use in dense networking environments such as data centers and high performance computing clusters where reliable, high-throughput interconnects are required.

Advantages

The active optical design delivers consistent high-speed performance with reduced crosstalk and improved signal quality compared to passive copper cables. QSFP+ connector compatibility ensures straightforward integration with a wide range of InfiniBand and 40GbE-capable switches, servers and storage nodes. The 2 m length provides flexibility for short rack-to-rack or within-rack connections while minimizing excess cable bulk. The optical medium lowers susceptibility to electromagnetic interference and can contribute to cooler, more reliable installations.

Suitable for

• Short-range connections between switches and servers in data centers
• Interconnects within high performance computing (HPC) clusters
• Links between storage arrays and compute nodes requiring low latency
• Environments where reduced electromagnetic interference is important

Key specifications

• Connector type: QSFP+ to QSFP+
• Transmission medium: active optical cable
• Length: 2 m
• Supported link: InfiniBand; compatible with 40GbE systems that accept QSFP+
• Latency: low-latency design suitable for high-throughput applications
• EMI: optical transmission reduces electromagnetic interference

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on compatible switches, servers or storage devices. Ensure connectors latch securely and that ports are powered according to the host device documentation. Allow for proper cable routing to avoid tight bends and maintain the manufacturer’s minimum bend radius. After connection, verify link status through device LEDs or management interfaces and confirm negotiated link speed and health in the host system.

Recommendations

For reliable operation, route the cable to avoid sharp bends and mechanical stress, maintain clear airflow in rack enclosures, and use compatible QSFP+ ports that support active optical modules. Verify firmware and driver compatibility on connected devices if link negotiation issues occur.
