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

CBO InfiniBand Active Optical Cable QSFP-AOC-20M-PT-BO is a 20 m QSFP-to-QSFP active optical link engineered for high-speed, low-latency interconnects between compatible switches, host adapters and servers. The cable uses active optical transceivers integrated into QSFP modules at both ends, providing optical signal transmission over a 20 metre span while eliminating the need for electrical copper between devices. The design reduces electromagnetic interference and provides electrical isolation, making it suitable for dense data centre and HPC environments where long-reach, reliable connectivity is required.

Advantages

The active optical construction delivers high bandwidth and low latency performance while keeping weight and cable bulk lower than equivalent copper alternatives. Integrated QSFP transceivers simplify installation with plug-and-play QSFP form-factor connections at each end, and optical transmission reduces susceptibility to electromagnetic interference. The 20 m length allows flexible rack-to-rack or row-to-row placement without intermediate transceivers, supporting tidy cable management and improved airflow in equipment racks.

Suitable for

• Direct QSFP-to-QSFP links between InfiniBand or compatible QSFP switches and adapters
• Data centre rack-to-rack or row-to-row interconnects requiring 20 m reach
• High-performance computing (HPC) clusters and low-latency compute fabrics
• Storage networks and SAN interconnects where optical isolation is preferred

Key specifications

• Connector type: QSFP to QSFP
• Length: 20 metres
• Transmission medium: active optical cable with integrated QSFP transceivers
• Designed for: InfiniBand and compatible QSFP-based high-speed links
• Benefits: electrical isolation and reduced electromagnetic interference
• Form factor: QSFP plug-and-play modules at both ends

How to use

Install the cable by inserting each QSFP connector into the corresponding QSFP port on your switches, host adapters or servers until the connector latches. Ensure both link endpoints support active optical QSFP modules and that ports are configured for the intended InfiniBand or QSFP protocol and speed. Manage cable routing to avoid sharp bends and maintain bend-radius recommendations from rack and transceiver manufacturers. After connection, verify link status through device LEDs or management interfaces and confirm the negotiated link speed and health in your networking or storage management software.

Recommendations

For reliable long-term operation, avoid tight bends and mechanical stress near the QSFP modules, maintain proper airflow in racks, and ensure firmware and driver compatibility on connected devices. Use the 20 m active optical cable where electromagnetic isolation and longer reach are required; for very short runs inside a single server chassis consider direct attach copper alternatives if supported by your equipment.
