CBO InfiniBand Active Optical Cable QSFP-AOC-5M-LS-BO 5 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-5M-LS-BO 5 m is a QSFP-form-factor active optical cable designed for high-speed InfiniBand connectivity. This 5 metre fiber link provides low-latency, long-reach interconnects between switches, hyperconverged infrastructure (HCI) nodes, servers and storage systems. The active optical design reduces electromagnetic interference and eases cable management in data center and high performance computing (HPC) environments while maintaining signal integrity over the extended distance.

Advantages

The active optical construction enables reliable high-bandwidth transmission with reduced signal loss compared to copper for the same reach. A standardized QSFP form factor ensures compatibility with QSFP ports on networking equipment and compute nodes, while the lightweight fiber cable simplifies routing and reduces rack congestion. The cable delivers low latency suitable for clustered systems and storage fabrics, and its optical medium minimizes susceptibility to electromagnetic interference in dense equipment racks.

Suitable for

• High-performance computing (HPC) clusters requiring low-latency interconnects
• Data centre switch-to-switch connections
• Interconnects between servers and shared storage arrays
• Hyperconverged infrastructure (HCI) deployments
• Environments where reduced electromagnetic interference and simplified cabling are required

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Type: Active optical cable (AOC)
• Length: 5 metres
• Interface: QSFP to QSFP
• Medium: Optical fibre
• Target application: InfiniBand high-speed interconnects
• Typical benefits: Low latency, reduced EMI, lightweight cabling

How to use

Install by cleanly inserting each QSFP connector into the corresponding QSFP port on your switch, server or storage device until it seats securely. Ensure devices are powered down or follow hot‑plug instructions from the equipment manufacturer if supported. Route the 5 m cable to avoid sharp bends and excessive tension; maintain the minimum bend radius specified by the equipment or fibre guidelines. After connection, verify link status and performance through the host or switch management interface and monitor for proper speed and errors.

Recommendations

Use this active optical cable in rack and aisle layouts that allow comfortable routing of a 5 m link and avoid tight cable bundles that may stress the fibre. For best results in latency-sensitive or high-throughput fabrics, pair the cable with compatible InfiniBand-capable hardware and verify firmware and driver support for QSFP AOC links. Store and handle connectors with protective caps when not in use and follow standard fibre handling practices to prevent contamination or damage.
