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

The CBO InfiniBand Active Optical Cable QSFP-AOC-30M-SS-BO 30 m QSFP+ to QSFP+ is a factory-terminated InfiniBand link for high-speed, low-latency rack-to-rack connections. This 30‑metre QSFP+ to QSFP+ active optical cable integrates optical transceivers inside the cable assembly, eliminating the need for separate external modules. It is designed for data centre environments to connect switches, servers and storage arrays that have QSFP+ ports, offering a compact, lightweight alternative to copper cabling with reduced electromagnetic interference.

Advantages

The active optical design delivers high bandwidth and low latency while maintaining signal integrity over a 30 m distance. Factory termination ensures consistent optical alignment and simplifies deployment without additional transceivers. The cable’s optical media reduces weight and bulk compared with equivalent copper solutions and minimises heat and EMI concerns in dense rack installations. Compatibility with QSFP+ ports provides a standardised interface for many InfiniBand and 10 Gigabit Ethernet systems.

Suitable for

• Rack-to-rack connections between QSFP+ switches in data centres
• Server-to-switch uplinks where QSFP+ ports are available
• Interconnects for storage arrays and high-performance compute clusters
• Environments requiring reduced electromagnetic interference and cable bulk

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector types: QSFP+ to QSFP+
• Length: 30 metres
• Transmission: Optical, factory-terminated
• Supported protocols: InfiniBand and compatible QSFP+ Ethernet implementations
• Design characteristics: Low-latency, high-bandwidth interconnect with reduced EMI

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on network switches, servers or storage devices. Ensure ports are powered down or follow hot-plug procedures recommended by the equipment manufacturer before insertion or removal. The factory-terminated connectors require no additional module installation; once seated and latched, the cable is ready for operation. Verify link status through connected devices and confirm that firmware or port settings match the intended InfiniBand or Ethernet configuration.

Recommendations

Route the cable to avoid sharp bends and mechanical strain; observe the manufacturer’s minimum bend radius. Use cable management within racks to prevent excessive tension on connectors. Confirm QSFP+ port compatibility and firmware support for active optical cables in your equipment before deployment. For best performance in dense deployments, maintain airflow and avoid obstructions that increase temperature around ports and cable harnesses.
