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

The InfiniBand Active Optical Cable CBO QSFP-AOC-30M-NK-BO is a 30 metre QSFP-to-QSFP optical link designed for data centre and high-performance computing (HPC) environments. This active optical cable integrates transceivers and optical fibre within a single assembly to provide a low-latency, high-bandwidth connection between QSFP ports. As an optical QSFP AOC, it eliminates the need for separate pluggable modules, reduces electrical cabling complexity and lowers heat and power compared with equivalent copper solutions.

Advantages

This 30 m InfiniBand QSFP AOC delivers stable high-speed connectivity with reduced electromagnetic interference and improved signal integrity over longer distances than passive copper. The integrated design simplifies installation and lowers rack density concerns by removing the need for additional transceivers. The optical medium reduces electrical power consumption at endpoints and helps maintain cooler operating temperatures in dense switch and server racks.

Suitable for

• High-performance computing clusters requiring low-latency interconnects
• Data centre switch-to-switch links across short to medium distances
• Server-to-switch and storage array interconnections with QSFP ports
• Environments where reduced heat and power consumption are priorities

Key specifications

• Connector type: QSFP to QSFP optical assembly
• Length: 30 metres
• Medium: Active optical cable with integrated transceivers and multimode/mode-appropriate fibre
• Application: InfiniBand and other QSFP-compatible high-speed interconnects
• Performance: Designed for low-latency, high-bandwidth links suitable for data centre and HPC traffic

How to use

Insert each QSFP connector into the corresponding QSFP port on the network device until the latch engages. No separate transceiver installations are required. Ensure ports are powered down or follow hot-swap procedures recommended by your hardware vendor if connecting to active equipment. Verify link status through the device management interface and configure port settings according to your network topology and InfiniBand or Ethernet requirements.

Recommendations

Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius and keep the cable away from high-heat sources. Use proper port and lane configuration consistent with your switch or host adapter documentation. For optimal performance in dense racks, plan airflow and cable routing to preserve cooling efficiency.
