BlueOptics Q28-AOC-2M-QN-BO InfiniBand optický kabel 2 m QSFP28 samec/samec

The BlueOptics Q28-AOC-2M-QN-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable intended for high-bandwidth interconnects. It uses QSFP28 form-factor connectors to support InfiniBand links and high-speed data transfer between servers, switches and network appliances. The cable provides a compact, flexible alternative to traditional copper or transceiver-based connections, designed for short-reach links inside racks and between adjacent racks in data centre and HPC deployments.

Advantages

This QSFP28 AOC combines high data-rate capability with low latency and electrical isolation, reducing interference and heat compared with copper alternatives. The fixed-length 2 m design simplifies cable management and ensures predictable signal integrity for short-distance interconnects. As an active optical cable it integrates transceivers and optical fibre in a single assembly, eliminating the need for separate SFP/QSFP transceivers and improving deployment convenience.

Suitable for

• High-performance computing clusters requiring InfiniBand connectivity
• Top-of-rack and middle-of-row switch interconnects in data centres
• Inter-server connections for low-latency storage and compute fabrics
• Equipment racks where a 2 m cable provides optimal routing without excess slack

Key specifications

• Length: 2 metres
• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Interface standard: InfiniBand-compatible high-speed link
• Use case: Short-reach, rack-to-rack and intra-rack connections

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on the devices being connected, ensuring the connector latch engages. No separate transceivers or module configuration is required beyond standard InfiniBand or switch settings. Route the cable to avoid sharp bends and mechanical stress; secure with cable management ties or channels as needed. If link LEDs or management interfaces provide diagnostic information, verify link status after installation to confirm proper operation.

Recommendations

For reliable performance, maintain minimum bend radius as specified by the manufacturer, avoid kinking or crushing the cable, and keep connectors free of dust. Use the 2 m length for short-reach paths within or between adjacent racks; for longer distances select an appropriate alternative. Follow your equipment vendor guidelines for InfiniBand link configuration and firmware compatibility.
