InfiniBand Active Optical Cable CBO QSFP-AOC-30M-LC-BO 30 m QSFP-to-QSFP

CBO QSFP-AOC-30M-LC-BO is a 30-metre active optical InfiniBand cable featuring QSFP connectors on both ends. The cable converts electrical signals to optical signals and back, allowing high-bandwidth data transfer across greater distances than copper while maintaining low latency and signal integrity. It is intended for use in data centres and high-performance computing clusters where reliable, high-speed interconnects are required for server-to-switch and switch-to-switch links.

Advantages

The active optical design delivers consistent signal quality over the full 30 m length and reduces electromagnetic interference compared with copper alternatives. QSFP-to-QSFP connectivity supports high aggregate bandwidth and compact port density, while the optical medium lowers heat dissipation in rack environments. The cable's plug-and-play QSFP terminations simplify installation and minimize the need for additional transceiver modules.

Suitable for

• Server-to-switch high-speed links in data centres
• Switch-to-switch interconnects in leaf-spine network topologies
• High-performance computing (HPC) cluster fabric connections
• Environments requiring reduced electromagnetic interference and improved signal integrity

Key specifications

• Connector type: QSFP on both ends
• Medium: active optical cable (AOC) with electrical-to-optical conversion
• Length: 30 metres
• Compatible link: InfiniBand high-speed interconnects
• Latency: designed for low-latency data transfer (typical for optical AOCs)
• Installation: plug-and-play QSFP terminations, no separate transceivers required

How to use

Connect each QSFP connector to the corresponding QSFP port on servers, switches or network adapters. Ensure that both ends are fully seated and that connected devices are powered and configured for the intended InfiniBand link speed. No external transceivers are required; the cable performs the optical conversion internally. After connection, verify link status through the host or switch management interface and monitor for expected link speed and health.

Recommendations

Route the cable carefully within racks and cable trays to avoid sharp bends and mechanical stress; maintain the manufacturer's minimum bend radius. Use this active optical cable where longer reach or reduced EMI is required compared with copper solutions, and confirm compatibility with your devices' QSFP port and supported InfiniBand speeds prior to deployment.
