CBO InfiniBand Active Optical Cable QSFP-AOC-20M-NG-BO — 20 m, QSFP connector

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-NG-BO — 20 m, QSFP connector is a 20-metre active optical direct-attach cable engineered for high-speed InfiniBand links between servers, switches and storage devices. As an active optical cable (AOC) with QSFP interfaces at both ends, it converts electrical signals to optical for transmission and back, enabling low-latency, high-bandwidth connections over longer distances than passive copper. The 20 m length supports flexible rack-to-rack and intra-row topologies while maintaining signal integrity suitable for data centre and high-performance computing environments.

Advantages

This active optical cable reduces signal loss and electromagnetic interference compared with copper alternatives, delivering consistent throughput and low latency across the 20 m span. The QSFP connectors provide compact, high-density port compatibility that helps conserve rack space and simplifies cabling. As an AOC, it requires no external transceivers or additional optics, simplifying installation and reducing component count in multi-vendor setups.

Suitable for

• High-performance computing clusters requiring low-latency interconnects
• Data centre switch-to-switch or switch-to-server connections up to 20 m
• Storage area network links and server uplinks where QSFP ports are available
• Environments seeking reduced interference and improved signal integrity versus copper

Key specifications

• Connector type: QSFP at both ends for quad-port high-density interfaces
• Length: 20 metres designed for rack-to-rack and intra-row cabling
• Media: active optical cable (AOC) for optical signal transmission
• Performance: suitable for high-bandwidth, low-latency InfiniBand links
• Compatibility: intended for devices with QSFP interfaces supporting InfiniBand protocols

How to use

Install by inserting each QSFP connector into the corresponding QSFP port on your server, switch or storage device until it latches. Ensure devices are powered down or follow hot-plug guidance from your hardware vendor if supported. Verify link status indicators on both devices after connection and configure network or InfiniBand settings as required by your environment. Avoid tight bends and ensure proper cable management to maintain optical performance over the 20 m span.

Recommendations

Route the cable following manufacturer bend-radius guidelines and keep it away from sources of mechanical strain and intense heat. Confirm QSFP compatibility and firmware recommendations on both ends for optimal interoperability. For installations in dense racks, label both ends and use proper strain relief to maintain long-term signal integrity.
