BlueOptics Q28-AOC-30M-CN-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male

The BlueOptics Q28-AOC-30M-CN-BO InfiniBand fibre optic cable 30m QSFP28 Male/Male is a 30-metre active optical cable designed for high-speed data transmission in data centres and high-performance computing environments. Featuring QSFP28 male connectors on both ends, this cable supports the bandwidth and latency requirements of InfiniBand networks and short-range high-throughput links. Its 30 m length provides flexibility for rack-to-rack and inter-rack connections while maintaining signal integrity through optical transmission.

Advantages

This optical cable offers low latency and high throughput suitable for InfiniBand deployments, with QSFP28 connector compatibility for modern server and switch ports. The active optical design reduces electromagnetic interference compared with copper alternatives and enables reliable long-reach connections within data centre layouts. The male-to-male QSFP28 configuration simplifies direct connections between compatible devices without additional transceivers.

Suitable for

• Rack-to-rack connections in data centres
• High-performance computing clusters and interconnects
• Low-latency InfiniBand links between switches and servers
• Short- to mid-range high-bandwidth optical links

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 Male to QSFP28 Male
• Length: 30 metres
• Application: InfiniBand high-speed data transmission
• Signal medium: Fibre optic

How to use

Verify that both endpoints have QSFP28 ports and that the devices support InfiniBand links. Power down or follow hot-swap procedures recommended by your hardware vendor before inserting the QSFP28 connectors. Align and insert each QSFP28 male connector into the corresponding port until it seats securely; observe mechanical latching if present. After connection, enable or configure the InfiniBand link via your network management tools and confirm link status and data rates. For removal, follow vendor guidance to avoid mechanical stress on ports and the cable.

Recommendations

Route the cable to avoid sharp bends and high-stress points; maintain bend radius recommended for optical cables. Use proper cable management in racks to prevent strain on QSFP28 connectors and ensure adequate airflow. Store and handle the cable in a clean environment to protect optical interfaces and avoid contaminating connector endfaces.
