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

The BlueOptics Q28-AOC-2M-PT-BO InfiniBand fibre optic cable 2m QSFP28 Male is a 2‑metre active optical cable designed for high‑speed interconnects in data centers and high‑performance computing environments. Featuring QSFP28 connectors on both ends, this cable supports the bandwidth and low latency requirements of InfiniBand links, enabling reliable short‑reach connections between switches, servers and storage systems. The cable's compact form factor and optical transmission reduce electrical interference and heat compared with equivalent copper solutions.

Advantages

This BlueOptics QSFP28 AOC provides a high‑throughput, low‑latency connection with reduced power consumption relative to copper cables for equivalent distances. The integrated optical transceivers eliminate the need for separate modules, simplifying installation and reducing component count. The 2 m length is suited to rack and cabinet interconnects while maintaining signal integrity for InfiniBand protocols. Materials and connector terminations are selected to ensure stable performance in continuous operation.

Suitable for

• Top‑of‑rack and end‑of‑row switch interconnects
• Server-to-switch links in data centres
• Storage array and compute node connections in HPC clusters
• Short‑reach InfiniBand fabric links requiring QSFP28 interfaces

Key specifications

• Connector type: QSFP28 on both ends (male)
• Length: 2 metres
• Transmission medium: active optical cable (AOC)
• Compatible protocol: InfiniBand (QSFP28 form factor)
• Use case: short‑reach, high‑bandwidth interconnects

How to use

Install the BlueOptics QSFP28 AOC by inserting each QSFP28 connector into the corresponding QSFP28 port on your network device until the latch engages. Ensure devices are powered down or follow hot‑swap guidelines from your hardware vendor if connecting live. Verify link operation through device management interfaces and monitor for correct data rates and link status. Avoid sharp bends in the cable and maintain recommended bend radius to preserve optical performance.

Recommendations

For optimal performance, use this 2 m QSFP28 AOC for intra‑rack or adjacent‑rack connections where short latency and high bandwidth are required. Keep the cable free from tight bends and mechanical strain, and follow the equipment manufacturer's port guidance for hot‑plugging and firmware compatibility checks.
