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

The BlueOptics Q28-AOC-3M-LE-BO InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre active optical cable designed to provide high-speed InfiniBand connectivity between compatible QSFP28 ports. Engineered for short-reach, high-bandwidth links in data centres and server environments, this cable supports reliable data transmission while reducing electromagnetic interference compared with copper alternatives. The male-to-male QSFP28 connectors ensure direct plug-and-play connection between networking equipment without additional transceivers.

Advantages

This BlueOptics InfiniBand cable offers low latency and high throughput suitable for demanding workloads. Its active optical design enables longer reach than passive copper options at comparable speeds and ensures stable signal integrity over the 3-metre distance. The compact QSFP28 form factor simplifies cabling density in racks and switches while reducing heat and power concerns associated with electrical interconnects.

Suitable for

• Direct connections between servers, switches and storage with QSFP28 ports
• High-performance computing (HPC) clusters and InfiniBand fabrics
• Data centre top-of-rack and leaf-spine interconnects
• Low-latency trading, virtualization and database throughput applications

Key specifications

• Cable type: active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 3 metres
• Supported interface: InfiniBand / Quad Small Form-factor Pluggable 28 (QSFP28)
• Designed for: high-bandwidth, short-reach interconnects
• Benefits: low latency, high throughput, immunity to electromagnetic interference

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your networking devices until the latch engages. Ensure devices are powered off or follow hot-swap guidance from your hardware vendor if connecting live. After connection, verify link status through device management interfaces or LED indicators to confirm proper negotiation and data rates. For optimal performance, route the cable to avoid tight bends and physical stress on the connectors.

Recommendations

To maintain signal integrity and product longevity, avoid bending the cable beyond the manufacturer’s minimum bend radius, keep connectors free of dust and debris, and handle the QSFP28 ends by the housing rather than the fibre region. Use in temperature-controlled racks and adhere to equipment vendor guidelines for cable routing and port population to ensure consistent high-speed operation.
