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

The CBO InfiniBand Active Optical Cable QSFP-AOC-30M-CN-BO is a 30-metre QSFP+ to QSFP+ active optical link engineered for high-speed data centre interconnects. This Active Optical Cable (AOC) delivers optical transmission without separate transceivers, providing a sealed optical path that reduces electromagnetic interference and simplifies installation in rack-to-rack or row-to-row deployments. The cable supports low-latency, high-bandwidth connections suitable for switch-to-switch links and high-performance computing clusters.

Advantages

The active optical construction offers stable signal integrity over a 30 m reach while reducing heat and power requirements compared with discrete transceiver plus fibre assemblies. The integrated QSFP+ connectors enable direct plug-and-play installation into QSFP+ ports, eliminating the need to handle separate SFP/QSFP transceivers and patch cords. The sealed optical design reduces susceptibility to electromagnetic interference and eases cable management in dense rack environments.

Suitable for

• Rack-to-rack data centre interconnects
• Row-to-row connections in server rooms
• Switch-to-switch links in core or aggregation layers
• High-performance computing (HPC) cluster interconnects
• Low-latency storage and compute fabrics

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: Active Optical Cable (AOC)
• Length: 30 metres
• Supported link: InfiniBand (QSFP+ interface)
• Data rate: supports QSFP+ class high-bandwidth links (compatible with 40Gb/s per lane aggregated bandwidth typical of QSFP+ implementations)
• Latency: low-latency optical transmission suitable for HPC and switch fabrics
• Design: sealed optical assembly to minimise electromagnetic interference

How to use

Install the cable by inserting each QSFP+ connector into the corresponding QSFP+ port on the switches, servers or adapters until the latch engages. Ensure devices are powered down or follow hot-plug procedures recommended by the equipment vendor if connecting under power. Route the cable to avoid sharp bends and maintain manufacturer-specified bend radius. Monitor link status indicators on connected devices to confirm a successful optical link.

Recommendations

For reliable operation, avoid tight bending, excessive pulling force and exposure to liquids or contaminants. Use this 30 m AOC for medium-distance data centre runs where a single-cable solution reduces installation complexity and EMI. Verify compatibility with your QSFP+ ports and InfiniBand or Ethernet over QSFP+ configurations before deployment.
