BlueOptics Q28-AOC-3M-FR-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-FR-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-speed InfiniBand links. It uses QSFP28 male connectors on both ends to deliver low-latency, high-bandwidth connectivity for servers, switches and storage systems in data centre and high-performance computing environments. The cable's construction enables reliable signal transmission over short to medium distances while keeping electromagnetic interference and heat generation minimal.

Advantages

This 3m QSFP28 AOC offers high data throughput with low latency suitable for InfiniBand networks, and its all-optical design reduces susceptibility to electromagnetic interference compared with copper alternatives. The QSFP28 male-to-male configuration provides straightforward compatibility with QSFP28 ports and simplifies cabling in dense rack environments. Its compact, flexible form factor supports neat cable routing and helps maintain airflow in server racks.

Suitable for

• Interconnects between QSFP28 ports on switches and routers
• Server-to-switch or server-to-storage links in data centres
• High-performance computing clusters requiring low-latency links
• Short-reach backbone connections in rack and row architectures

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Interface: InfiniBand-compatible, QSFP28 form factor
• Performance: Designed for high bandwidth and low latency transmission
• Construction: Optical fiber cores with integrated transceivers

How to use

Install the cable by inserting each QSFP28 male connector into corresponding QSFP28 ports on network devices until the connector locks into place. Ensure ports are powered down if recommended by your hardware vendor before insertion or removal to avoid potential hot-plug issues. Route the cable to avoid tight bends and maintain the minimum bend radius specified by the device or cable manufacturer. For best performance, keep optical interfaces clean and free of dust by using appropriate cleaning tools before making connections.

Recommendations

Use this BlueOptics QSFP28 AOC for short to medium reach InfiniBand links inside racks and between adjacent racks. Verify compatibility with device QSFP28 port specifications and keep optical connectors protected when not in use. Avoid excessive bending or tensile stress, and follow your equipment manufacturer's guidelines for hot-plug operations and transceiver handling.
