CBO InfiniBand Active Optical Cable QSFP-AOC-5M-LE-BO — 5 m, QSFP+ to QSFP+

CBO InfiniBand Active Optical Cable QSFP-AOC-5M-LE-BO is a 5 metre active optical link with QSFP+ connectors on both ends, designed for high-speed data centre and HPC interconnects. The cable converts electrical signals to optical for transmission and back at the far end, delivering low latency and high bandwidth performance between compatible QSFP+ ports. Its optical construction provides immunity to electromagnetic interference and supports rack-to-rack or intra-rack connections where extended reach and signal integrity are required.

Advantages

The active optical design reduces power consumption and heat compared with equivalent copper direct-attach cables at similar lengths while maintaining QSFP+ compatibility for seamless integration into existing infrastructures. The 5 m length balances reach and manageability for dense rack environments and data centre layouts. Low-latency transmission and high bandwidth capability make this cable suitable for performance-sensitive applications, and optical isolation eliminates ground loop and EMI concerns common with copper cabling.

Suitable for

• Rack-to-rack high-speed links in data centres
• Intra-rack connections between switches, routers and servers
• High-performance computing clusters requiring low latency
• Environments where EMI immunity and optical reach are needed

Key specifications

• Connector type: QSFP+ to QSFP+
• Length: 5 metres
• Transmission medium: active optical cable
• Performance: designed for InfiniBand high-speed links and QSFP+ ports
• Latency: low-latency optical transmission suitable for HPC
• EMI immunity: inherent optical isolation

How to use

Install the QSFP-AOC-5M-LE-BO by inserting each QSFP+ connector into compatible QSFP+ ports on network switches, host adapters or routers. Ensure connectors are oriented correctly and fully seated until the connector latch engages. No external power supply is required beyond the host ports; the active modules draw required operating power from the connected QSFP+ ports. Verify link status on connected devices and confirm speed and lane configuration through the host equipment management interface.

Recommendations

Handle the cable by the connector housings and avoid tight bends; adhere to the manufacturer’s minimum bend radius to maintain optical performance. Route the cable to minimise tension and avoid exposure to sources of mechanical damage. Use in systems and ports that explicitly support QSFP+ active optical cables and check device firmware compatibility if required for link negotiation.
