CBO InfiniBand Active Optical Cable QSFP-AOC-20M-SW-BO 20 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-20M-SW-BO 20 m is a factory-terminated fiber link designed for high-speed InfiniBand interconnects. This active QSFP AOC converts electrical signals to optical signals within the cable assembly, enabling reliable data transmission over a 20 meter distance while reducing susceptibility to electrical interference. Suited for dense rack environments, the cable supports low-latency connections between compatible QSFP ports and is intended for deployments where longer reach or improved signal integrity is required compared with copper direct-attach solutions.

Advantages

Active optical technology provides signal conditioning and conversion inside the cable, allowing stable high-bandwidth links without external transceivers. The 20 m length extends reach between racks and switches while keeping a single-cable footprint and simplified cable management. Optical transmission reduces electromagnetic interference and crosstalk, improving link reliability in crowded data center environments. The QSFP form factor supports compatibility with QSFP InfiniBand ports on servers, switches and adapters that accept active AOC assemblies.

Suitable for

• Inter-rack connections in data centers and server rooms
• High-performance computing (HPC) clusters requiring low latency
• Switch-to-switch or switch-to-host links with QSFP InfiniBand ports
• Environments where reduced electromagnetic interference is important

Key specifications

• Cable type: Active Optical Cable (AOC) with QSFP interfaces
• Length: 20 meters
• Connector type: QSFP form factor on both ends for InfiniBand ports
• Transmission medium: multimode optical fiber with integrated active optics
• Performance: designed for low-latency, high-bandwidth InfiniBand links
• Designed use: factory-terminated, plug-and-play cable assembly for direct QSFP connections

How to use

Power is supplied through the connected QSFP ports, so no external power source is required. To install, align each QSFP connector with the corresponding port on your InfiniBand switch, adapter or server and insert until the latch engages. Verify the link status via the host or switch management interface and monitor for expected link speed and error-free operation. Handle the cable by the connector housings and follow standard fiber care practices when routing to avoid tight bends or excessive stress on the assembly.

Recommendations

Route the cable through existing cable trays or management arms to maintain bend radius and prevent kinking. Avoid sharp bends and secure the cable at intervals to reduce strain on connectors. Confirm compatibility with your hardware vendor’s list of supported AOC assemblies before deployment and monitor link statistics after installation to ensure optimal performance.
