CBO InfiniBand aktívny optický kábel QSFP-AOC-20M-LO-BO — QSFP, 20 m

The CBO InfiniBand Active Optical Cable QSFP-AOC-20M-LO-BO — QSFP, 20 m is an active optical link designed for high-speed InfiniBand interconnects. This 20-meter QSFP-form-factor AOC provides a fiber-optic connection between compatible QSFP ports to support low-latency, high-throughput data transfers in data centers, server rooms and HPC clusters. It is intended for longer rack-to-rack or equipment-to-equipment links where copper cables are impractical or would introduce signal integrity or distance limitations.

Advantages

The cable combines optical transmission with a QSFP plug-and-play interface to deliver reliable, high-bandwidth connectivity over 20 meters while reducing electromagnetic interference and heat generation compared with equivalent copper solutions. Its fixed length and integrated transceivers simplify deployment by eliminating the need for separate SFP/QSFP transceivers and patch cords. The design supports typical InfiniBand performance characteristics such as low latency and stable throughput under sustained loads.

Suitable for

• Rack-to-rack interconnects in data centers and colocation facilities
• Connections between servers, switches and storage systems with QSFP ports
• High-performance computing clusters requiring low-latency links
• Environments where electromagnetic interference or cable weight are concerns

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Length: 20 meters
• Transmission medium: optical fiber
• Typical use: InfiniBand interconnects for data centres and HPC
• Advantages over copper: reduced EMI, lower heat output, longer reach

How to use

Install by inserting each QSFP connector into compatible QSFP ports on the host devices, ensuring secure seating and proper orientation. No separate transceivers are required; the integrated optics initialize automatically with supported host hardware. Verify that connected devices support the InfiniBand protocol and the QSFP AOC interface, then check link status and speed via the host management tools. Handle the cable by the connectors and avoid sharp bends near the cable ends to preserve optical performance.

Recommendations

For reliable operation, route the cable to avoid tight bends and excessive tension; maintain the minimum bend radius recommended for optical fiber AOCs. Use in compatible QSFP ports only and verify firmware or driver support on switches and servers when integrating into existing InfiniBand networks. Periodically inspect connectors for contamination and clean with appropriate fiber-optic cleaning tools if necessary.
