Aktívny optický kábel CBO BlueOptics QFX-QSFP-AOC-20M 20 m, QSFP+ na QSFP+, multimódový

CBO BlueOptics QFX-QSFP-AOC-20M is a 20-meter active optical cable with QSFP+ connectors on both ends designed for short-range, high-bandwidth interconnects in data center environments. As an active optical cable (AOC) it integrates optical transceivers into the cable assemblies, enabling optical signal transmission over multimode fiber without separate external transceivers. The cable supports direct QSFP+ to QSFP+ connections between servers, switches and storage systems, reducing rack cabling complexity and improving signal integrity for links where low latency and reliable throughput are required.

Advantages

The AOC design provides reduced electromagnetic interference and lower weight compared with equivalent copper assemblies, while simplifying installation by eliminating the need for discrete transceiver modules. A single, factory-terminated cable delivers consistent optical performance across its 20 m length and reduces points of failure associated with multiple connectorized components. Multimode fiber transmission maintains high data rates over the specified distance and is suitable for dense rack-to-rack and equipment-to-equipment connections.

Suitable for

• High-speed QSFP+ interconnects between switches and aggregation devices
• Server-to-switch and server-to-storage connections in data centers
• Rack-to-rack optical links in short-range enterprise and colocation environments
• High-bandwidth applications requiring low latency and stable throughput

Key specifications

• Connector type: QSFP+ to QSFP+
• Cable type: Active optical cable (AOC) over multimode fiber
• Length: 20 meters
• Bandwidth: Designed for QSFP+ data rates (40 Gbps aggregate per cable, device-dependent)
• Form factor: Factory-terminated, integrated transceiver assemblies
• Use environment: Data center short-reach links, rack-to-rack connections

How to use

Install the cable by inserting each QSFP+ connector into the appropriate QSFP+ port on the devices to be linked, ensuring the connector latch is engaged. Verify device compatibility with QSFP+ ports and confirm that the host equipment supports active optical cables. Route the cable along cable management paths to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius for multimode fiber assemblies. After physically connecting, confirm link status and data rates through the devices' management interfaces and check for any port or firmware requirements that may affect operation.

Recommendations

Use the AOC in controlled data center environments where short-reach multimode links are preferred. Avoid exposure to excessive heat, moisture, or sharp bends; ensure correct port orientation and compatibility before insertion to prevent connector damage. For critical deployments, test links after installation and monitor link state and throughput to validate expected performance.
