InfiniBand active optical cable CBO QSFP-AOC-20M-MV-BO 20 m QSFP+ to QSFP+

The InfiniBand active optical cable CBO QSFP-AOC-20M-MV-BO is a 20-metre QSFP+ to QSFP+ direct optical link engineered for high-speed server, switch and storage interconnects. This active optical cable delivers optical transmission across a 20 m span without the need for separate transceivers, enabling compact QSFP+ form-factor connections that reduce port occupancy and simplify rack cabling. The design targets data centre applications where low latency, high bandwidth and immunity to electromagnetic interference are important.

Advantages

This active optical cable combines long-reach optical performance with the compact QSFP+ connector, providing a reliable 20 m link that eliminates the need to install and manage separate transceivers and patch cords. The optical medium ensures immunity to EMI and reduces signal attenuation over the specified distance, while the plug-and-play QSFP+ interface simplifies insertion and removal. The integrated active electronics are optimised for InfiniBand environments to preserve low latency and high throughput.

Suitable for

• Data centre switch-to-switch uplinks within and between server racks
• High-performance computing (HPC) cluster interconnects
• Server-to-storage connections requiring low latency and high bandwidth
• Environments where electromagnetic immunity and reduced cabling complexity are desired

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: active optical cable (AOC)
• Nominal length: 20 metres
• Application: InfiniBand high-speed interconnects
• Form factor: compact QSFP+ module interface
• Performance characteristics: low latency, high bandwidth suitable for data centre links
• Environmental advantage: optical transmission provides immunity to electromagnetic interference

How to use

Insert each QSFP+ connector into the corresponding QSFP+ port on networking equipment such as switches, servers or storage nodes until the latch engages. Ensure ports are compatible with InfiniBand QSFP+ interfaces and that connected devices are powered and configured for the expected data rates. Route the cable through the rack and cable management pathways to avoid tight bends and mechanical strain on the connectors. No separate transceivers are required; the cable provides a complete link when both ends are correctly seated.

Recommendations

Avoid tight bends and excessive pulling forces on the cable; maintain the minimum bend radius recommended for active optical cables. Verify device compatibility with QSFP+ AOC links and confirm firmware or driver support for InfiniBand operation if required. For permanent installations, secure the cable with appropriate management clips to prevent stress on ports and to maintain signal integrity.
