InfiniBand Active Optical Cable CBO QSFP-AOC-20M-SO-BO 20 m QSFP+ to QSFP+

CBO InfiniBand active optical cable QSFP-AOC-20M-SO-BO is a 20-meter QSFP+ to QSFP+ active optical link intended for high-speed interconnects in data centers. The cable integrates optical transceivers inside the assembly to provide a plug-and-play connection between QSFP+ ports without separate SFP/QSFP transceivers. Designed for rack-to-rack and intra-rack use, this 20 m AOC delivers a lightweight, low-latency optical connection for servers, switches and storage systems where reliable point-to-point connectivity and signal integrity are required.

Advantages

The active optical construction reduces electromagnetic interference and provides improved signal integrity compared with copper twinax at similar distances. At 20 meters, the cable eliminates the need for separate transceiver modules and fiber patching, simplifying installation and reducing component count. The QSFP+ to QSFP+ assembly offers a compact form factor with low weight, enabling easier cable routing in dense racks while maintaining the high throughput and low latency expected for InfiniBand fabrics.

Suitable for

• Rack-to-rack high-speed links between switches and routers
• Intra-rack connections for server-to-switch or storage-to-switch interconnects
• InfiniBand fabrics requiring low latency and stable optical links
• Data center deployments seeking to reduce connector and transceiver inventory

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 20 meters
• Cable type: Active optical cable (AOC)
• Supported protocol: InfiniBand / QSFP+ electrical/optical interface
• Latency: Low-latency optical link suitable for high-performance interconnects
• Weight: Lightweight assembly for improved cable management
• Environmental: Designed for data center indoor use

How to use

Install the QSFP-AOC-20M-SO-BO by inserting each QSFP+ connector into compatible QSFP+ ports on your devices until the latch engages. The active optical cable is plug-and-play and typically requires no additional configuration or external transceivers. Ensure both endpoints are powered and that the host ports support QSFP+ AOC connections and the relevant InfiniBand or Ethernet link settings. Route the cable to avoid tight bends; follow device vendor guidelines for port compatibility and link speed configuration.

Recommendations

For reliable performance, maintain bend radius guidelines specified for active optical assemblies, avoid exposure to excessive mechanical stress, and use the cable in controlled indoor data center environments. Verify port compatibility and firmware support on switches and host adapters before deployment to ensure optimal link negotiation and performance.
