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

Active Optical Cable CBO QSFP-AOC-20M-SP-BO is a 20-metre InfiniBand QSFP+ to QSFP+ link manufactured by BlueOptics. The factory-terminated blue cable integrates optical transceivers into the cable assembly, delivering a plug-and-play solution for high-speed server, switch and storage interconnects. Designed for short-reach data centre environments and HPC racks, this AOC offers low latency and reduced power consumption compared with equivalent copper links while removing the need for separate transceiver modules.

Advantages

This 20 m InfiniBand active optical cable provides deterministic signal quality across the full length and eliminates field termination. Its integrated optics reduce module count in switches and servers, lowering total power draw and simplifying installation. The factory termination and robust cable jacket increase reliability for dense rack deployments, and the QSFP+ to QSFP+ form factor ensures compatibility with standard QSFP ports supporting InfiniBand and high-speed Ethernet interconnects.

Suitable for

• Inter-rack links between switches and leaf/spine fabrics in data centres
• Server-to-switch connections in high-performance computing (HPC) clusters
• Storage array interconnects and SAN backplanes requiring low-latency links
• Short-reach optical replacement for copper QSFP+ DACs to reduce power and heat

Key specifications

• Length: 20 metres
• Connector type: QSFP+ to QSFP+
• Optical type: Active Optical Cable (factory-integrated transceivers)
• Supported interface: InfiniBand (QSFP+ form factor); compatible with QSFP+ high-speed ports
• Cable jacket colour: blue
• Designed for short-reach data centre and HPC rack environments

How to use

Install by inserting each QSFP+ connector into the corresponding QSFP+ port on the devices to be linked, ensuring the latch engages. No additional transceiver modules or fibre patching are required. Verify link status via device LEDs or management interfaces after connection. Route the cable to avoid sharp bends; follow equipment vendor guidelines for QSFP+ handling and hot-plug procedures. For optimal performance, maintain a clean environment around connector interfaces and avoid excessive mechanical strain on the cable assembly.

Recommendations

Use this AOC for short-reach connections inside racks or between adjacent racks where a reliable, low-latency optical link is required. Avoid outdoor runs or environments with temperatures and mechanical stresses outside standard data centre specifications. For longer distances or different transceiver standards, evaluate appropriate optical modules or single-mode solutions.
