Cavo ottico attivo InfiniBand CBO QSFP-AOC-2M-QL-BO, QSFP a QSFP, 2 m

CBO InfiniBand Active Optical Cable QSFP-AOC-2M-QL-BO, QSFP to QSFP, 2 m is a 2‑metre QSFP-to-QSFP active optical link designed for high-speed InfiniBand interconnects between servers, switches and storage systems. The cable integrates electrical-to-optical conversion within QSFP modules at each end, delivering low latency and high bandwidth over short distances while reducing electromagnetic interference and the power draw associated with equivalent copper assemblies.

Advantages

The active optical construction provides consistent signal integrity and longer reach within data centre racks compared with passive copper cables of similar length. Integrated transceivers enable plug-and-play connectivity with standard QSFP ports, while the optical medium reduces crosstalk and EMI. The 2 m length simplifies rack-to-rack and in-rack connections by removing the need for separate transceivers and fibre patching, and contributes to lower power consumption and improved thermal behaviour in densely packed installations.

Suitable for

• High-performance computing clusters using InfiniBand fabrics
• Server-to-switch and switch-to-switch links within racks and adjacent racks
• Storage systems requiring low-latency, high-bandwidth connections
• Short-range data centre interconnects where EMI reduction is important

Key specifications

• Connector type: QSFP on both ends for direct QSFP-to-QSFP connection
• Length: 2 metres
• Cable type: Active optical cable with integrated electrical-to-optical conversion
• Supported link: InfiniBand high-speed interconnects (QSFP form factor)
• Performance attributes: low latency, high bandwidth suitable for short-reach applications
• EMI characteristics: reduced electromagnetic interference compared with copper equivalents

How to use

Insert each QSFP module into the corresponding QSFP port on the devices to be connected, ensuring the latch engages and the module is fully seated. No separate transceivers or fibre connectors are required; the cable provides integrated optical conversion and signal routing. After installation, verify link status through the host devices or switch management interface and monitor for expected port speeds and error-free operation. For removal, disengage the latch and pull the module straight out to avoid bending the cable near the connector.

Recommendations

Use the cable in rack and short-distance topologies where a 2 m QSFP-to-QSFP link matches device placement. Maintain gentle bend radii and avoid tight kinks near the QSFP modules. Verify compatibility with equipment QSFP port firmware and supported InfiniBand speeds before deployment, and keep the connectors clean and protected when not in use.
