CBO InfiniBand Cavo ottico attivo QSFP-AOC-20M-IA-BO — 20 m

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-IA-BO — 20 m is a 20-metre active optical link with QSFP form factor designed for InfiniBand networks. The cable provides a fiber-based connection between QSFP ports on servers, switches and storage devices, delivering high bandwidth and low latency over longer distances than equivalent copper solutions. As an active optical cable, it integrates optical transceivers and a duplex fiber link in a single assembly for plug-and-play installation in data centre and high-performance computing environments.

Advantages

The active optical design reduces signal attenuation and electromagnetic interference while extending reach compared with passive copper assemblies. The QSFP form factor supports high aggregate data rates and maintains low latency suitable for InfiniBand fabrics. The integrated transceiver modules eliminate the need for separate optics and patch cords, simplifying cabling and reducing port-to-port signal loss. The 20-metre length enables flexible rack-to-rack or aisle connections without additional repeaters.

Suitable for

• Server-to-switch interconnects in data centres
• Switch-to-switch links in high-performance computing clusters
• Storage array connections requiring low-latency bandwidth
• Longer rack-to-rack or across-aisle cabling where copper reach is insufficient

Key specifications

• Interface: QSFP (quad small form-factor pluggable) connector
• Type: Active optical cable with integrated optical transceivers
• Length: 20 metres
• Protocol compatibility: InfiniBand-compatible link layer and electrical signalling
• Performance: High-bandwidth, low-latency optical transmission suitable for HPC and data centre interconnects
• Cabling: Duplex multimode optical fiber within a single assembly

How to use

Install the cable by inserting each QSFP connector into compatible QSFP ports on the devices to be connected. Ensure both ends are fully seated and the latch mechanisms engage to secure the connection. Verify port configuration and link status on connected devices according to the host and switch documentation. Active optical cables are plug-and-play but may require firmware or driver support matching the InfiniBand implementation in the environment. Avoid excessive bending of the cable and follow vendor-recommended minimum bend radius to preserve optical performance.

Recommendations

For reliable operation, route the cable to avoid tight bends, compressive forces, or heat sources. Use appropriate airflow and cable management in racks and ensure QSFP ports are clean before insertion. Confirm compatibility with your InfiniBand switches and host adapters and, where available, use device diagnostics to monitor link health and performance.
