CBO Cabo Ótico Ativo InfiniBand QSFP-AOC-20M-RW-BO 20 m

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-RW-BO 20 m is a 20‑metre active optical link with QSFP form‑factor connectors designed for InfiniBand networks. It provides an optical alternative to copper direct-attach cables for short‑reach interconnects between servers, switches and storage systems. The cable is engineered to minimise latency and eliminate electromagnetic interference, delivering consistent high-speed connectivity across a 20 m span suitable for dense rack and row topologies in data centres and high-performance computing environments.

Advantages

The active optical construction reduces signal attenuation over the 20 m distance compared with passive copper while maintaining low latency characteristics required by InfiniBand workloads. QSFP connectors enable high port density and straightforward plug‑and‑play installation without additional transceivers. As an optical cable, it is immune to electromagnetic interference and improves thermal behaviour in constrained rack spaces by removing bulky copper assemblies.

Suitable for

• Server-to-switch and switch-to-switch interconnects in data centres
• High-performance computing clusters requiring low-latency links
• Storage area network connections and SAN fabrics
• Racks and top-of-rack installations with 20 m reach requirements

Key specifications

• Connector type: QSFP (Quad Small Form-factor Pluggable)
• Cable type: Active Optical Cable (AOC)
• Length: 20 metres
• Compatibility: Designed for InfiniBand interconnects
• Signal characteristics: Low-latency optical transmission, EMI immunity
• Use environment: Data centre and HPC short-range optical links

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on switches, servers or storage devices until the connector latches. Ensure ports are powered down or follow hot‑swap guidelines from your equipment vendor if connecting live. Route the cable to avoid sharp bends and mechanical stress; maintain the minimum bend radius specified by the equipment manufacturer. After connection, verify link status and performance using the host or switch management tools and monitor for expected link speed and latency.

Recommendations

For reliable operation, use the cable within typical data centre temperature ranges, avoid excessive bending or crushing, and keep connectors clean and covered when not in use. Confirm QSFP port compatibility and firmware support on both ends before deployment to ensure optimal InfiniBand link performance.
