BlueOptics Q28-AOC-2M-CP-BO InfiniBand optický kábel 2 m QSFP28 konektor samec/konektor samec

The BlueOptics Q28-AOC-2M-CP-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable designed for high-throughput short-reach interconnects. Equipped with QSFP28 male connectors on both ends, this cable supports high-speed data transfer suitable for dense server and switch interconnections in data centres and high-performance computing clusters. The cable's compact length and optical transmission reduce latency and electromagnetic interference compared with copper alternatives.

Advantages

This active optical cable offers high bandwidth and low latency for InfiniBand links while maintaining a flexible form factor that simplifies cable routing in rack environments. The QSFP28 male/male interface enables direct connections between compatible ports without additional transceivers. Being optical, the cable provides immunity to electromagnetic interference and a reduced thermal footprint compared with equivalent copper assemblies.

Suitable for

• Short-reach server-to-switch connections in data centres
• High-performance computing cluster interconnects
• Switch-to-switch uplinks where QSFP28 ports are available
• Environments requiring reduced EMI and compact cabling

Key specifications

• Length: 2 metres
• Connector type: QSFP28 male to QSFP28 male
• Media: active optical cable (AOC)
• Protocol compatibility: InfiniBand (high-speed serial data)
• Use case: short-reach high-bandwidth interconnects

How to use

Ensure both devices support QSFP28 ports and the InfiniBand protocol before connecting. Insert each QSFP28 connector into the corresponding port until the latch engages. Verify link status on the connected devices and check for correct data rates and lane configuration in the host or switch management interface. To remove, depress the connector latch and pull the module straight out, avoiding bending the cable sharply.

Recommendations

Route the cable to avoid tight bends and mechanical stress; maintain the manufacturer’s minimum bend radius. Use appropriate airflow considerations in racks and avoid placing heavy objects on the cable. For reliable operation, match port speed settings on both ends and monitor link health through device diagnostics.
