Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-2M-IX-BO 2m QSFP28 macho/macho

The BlueOptics Q28-AOC-2M-IX-BO InfiniBand fibre optic cable is a 2-meter active optical cable with QSFP28 male connectors on both ends. It is engineered for high-throughput, low-latency links in data centre and high-performance computing environments where reliable short-range optical interconnects are required. The cable supports InfiniBand signalling over an optical active link, offering a compact and power-efficient alternative to separate transceiver and patch-cord combinations.

Advantages

This active optical cable provides high data-rate transmission with reduced electromagnetic interference and improved signal integrity compared with copper equivalents. Its QSFP28 male-to-male configuration enables direct connection between compatible QSFP28 ports without additional transceivers, simplifying rack cabling and reducing component count. The 2 m length balances reach and neat cable management in rack or chassis-to-chassis connections, while the optical construction helps maintain thermal efficiency in dense installations.

Suitable for

• Short-range interconnects between servers, switches and storage in data centres
• High-performance computing clusters requiring InfiniBand links
• Top-of-rack and end-of-row cabling where QSFP28 ports are available
• Environments seeking to minimize electromagnetic interference and heat from copper cabling

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 2 metres
• Supported link: InfiniBand high-speed optical link
• Form factor: Compact, multi-lane QSFP28 design
• Typical use: Short-range data centre interconnect

How to use

Install the cable by inserting each QSFP28 male connector into the corresponding QSFP28 port on your devices until the latch engages. Ensure ports are powered down or follow hot-plug procedures recommended by your equipment vendor if connecting live. Verify link status through device management interfaces or LEDs and confirm connectivity and negotiated link speed per the host equipment. Route the cable to avoid sharp bends and maintain the specified minimum bend radius to prevent signal degradation.

Recommendations

Handle the cable by the connector housings and avoid pulling on the optical fibres. Maintain bend radius and avoid tight strain or kinking. Use this 2 m QSFP28 InfiniBand AOC for short-reach connections inside racks or between adjacent racks; for longer distances, consult alternative optical solutions. Follow your hardware vendor’s guidance for firmware and compatibility checks to ensure reliable operation.
