BlueOptics Q28-AOC-2M-QL-BO InfiniBand/fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-QL-BO InfiniBand/fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable designed for high-speed interconnects in data centres and enterprise network environments. With QSFP28 connectors on both ends, this cable supports short-distance, high-bandwidth links between switches, routers, servers and storage arrays where low latency and signal integrity are required.

Advantages

This 2 m QSFP28 active optical cable provides high data throughput and improved electromagnetic immunity compared to copper alternatives, with reduced heat generation and lower weight for easier cable management. The male-to-male QSFP28 terminations ensure straightforward plug-and-play installation into compatible ports, minimizing setup time. The optical transmission preserves signal quality over the 2-metre span, supporting reliable operation in dense rack and chassis configurations.

Suitable for

• High-performance server-to-switch connections in data centres
• Inter-switch links for aggregation and spine-leaf architectures
• Server-to-storage high-bandwidth links
• Short-reach, low-latency InfiniBand or Ethernet QSFP28 deployments

Key specifications

• Connector type: QSFP28 Male to QSFP28 Male
• Cable type: Active Optical Cable (AOC)
• Length: 2 metres
• Typical application: InfiniBand and high-speed fibre optic networking
• Designed for: 100 Gbps class QSFP28 links (short-reach)
• Form factor: Compact QSFP28 plug for dense installations

How to use

Insert each QSFP28 connector into the appropriate device port until the latch engages. Ensure both endpoints support QSFP28 active optical connections and that firmware or port settings are configured for the intended protocol (InfiniBand or Ethernet). Route the 2 m cable carefully to avoid sharp bends; maintain recommended bend radii and avoid compressive stress on the connectors. No separate transceivers or patch cords are required when using this AOC between compatible QSFP28 ports.

Recommendations

For optimal performance, verify compatibility with the host devices and confirm link settings after installation. Avoid excessive bending near the connector boot and maintain a clean environment to prevent contamination of connector interfaces. Use the 2 m length for short-reach links inside racks or between adjacent racks to minimize signal loss and latency.
