Cable óptico activo InfiniBand CBO QSFP-AOC-20M-NK-BO 20 m QSFP+ a QSFP+

The InfiniBand Active Optical Cable CBO QSFP-AOC-20M-NK-BO 20 m QSFP+ to QSFP+ is a fiber-based interconnect designed for high-speed data centre environments. The 20 metre AOC combines QSFP+ form-factor connectors with integrated optical transceivers to enable low-latency, high-bandwidth links between servers, switches and storage systems. By using optical transmission rather than copper, the cable reduces electromagnetic interference and supports stable short-to-mid-range connections where consistent signal integrity is required.

Advantages

This Active Optical Cable delivers a high-bandwidth, low-latency connection in a single, factory-terminated assembly, eliminating the need for separate transceivers and patch cords. The QSFP+ connectors on both ends ensure compatibility with common InfiniBand and QSFP+-capable devices. The optical medium provides immunity to electrical noise and enables lighter, more flexible routing within racks and between equipment. The fixed 20 m length simplifies deployment planning for typical data centre topologies.

Suitable for

• Connecting QSFP+-equipped servers to top-of-rack or leaf switches
• Interconnecting storage arrays and high-performance computing nodes
• Short-to-mid-range links inside data centre aisles and between adjacent racks
• Environments requiring low electromagnetic interference and consistent signal quality

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: Active Optical Cable (AOC) with integrated optical transceivers
• Length: 20 metres
• Supported interface: InfiniBand and QSFP+ compatible high-speed links
• Transmission medium: optical fiber for reduced EMI and higher signal integrity
• Typical use range: short-to-mid-range data centre interconnects

How to use

Install the cable by inserting the QSFP+ connector plugs into the corresponding QSFP+ ports on each device until the retention latch engages. Ensure both ends are connected to compatible QSFP+ ports with support for InfiniBand or the required Ethernet/Fabric protocol. Avoid sharp bends and maintain the manufacturer’s minimum bend radius for optical assemblies. For hot-pluggable deployments, verify link status indicators on connected equipment and confirm negotiated speed and lane configuration through device management interfaces.

Recommendations

Route the AOC within rack cable management channels and avoid tight bundling with power cabling to preserve optical performance. When planning deployments, choose the 20 m length for connections where this reach reduces the need for intermediate patching while keeping slack and strain relief accessible at each port. Inspect connector endfaces before insertion and keep protective caps on unused ends during storage.
