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

The BlueOptics Q28-AOC-3M-SW-BO InfiniBand fibre optic cable is a 3-meter active optical cable with QSFP28 male-to-male connectors, engineered for high-speed server, switch and storage interconnects. It supports low-latency, high-throughput links commonly required in data centre and high-performance computing environments. The compact QSFP28 form factor and fixed 3 m length provide a straightforward solution for short-reach connections inside racks or between adjacent racks.

Advantages

This InfiniBand fibre optic cable delivers stable signal integrity and minimal latency through optical transmission, reducing electromagnetic interference compared with copper alternatives. The QSFP28 male-to-male design simplifies direct device-to-device connections without additional transceivers. A fixed 3 m length offers predictable routing and cable management within dense networking setups. The cable is designed to be hot-pluggable and to comply with QSFP28 physical standards for compatibility with equipment that accepts QSFP28 AOC modules.

Suitable for

• High-performance computing clusters and InfiniBand fabric links
• Server-to-switch and switch-to-switch connections in data centres
• Low-latency storage networking and SAN interconnects
• Short-reach rack-to-rack links where QSFP28 interfaces are available

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 m
• Application: InfiniBand high-speed data links and compatible QSFP28 ports
• Transmission medium: Optical fiber for reduced EMI and high bandwidth
• Form factor: QSFP28 compact module suitable for dense port panels

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on devices that support InfiniBand or compatible optics. Ensure ports are powered and compatible with active optical cables before hot-plugging. Route the 3 m cable to avoid sharp bends and mechanical stress on the connectors; maintain manufacturer-recommended bend radius for optical fiber. After connection, verify link status through device management interfaces and monitor for expected throughput and latency.

Recommendations

Use this 3 m QSFP28 AOC for short-reach links within racks or between adjacent racks where InfiniBand performance and low latency are required. Avoid exposing the cable to excessive mechanical strain, liquids, or extreme temperatures. For longer runs or different port types, choose appropriate transceivers or cable types to match required distances and interfaces.
