BlueOptics 100G-QSFP28-AOC3M-BO InfiniBand fibre optic cable 3 m

The BlueOptics 100G-QSFP28-AOC3M-BO InfiniBand fibre optic cable 3 m is a factory-terminated active optical cable (AOC) that provides a direct, low-latency 100 Gbps link over a 3-metre distance. Equipped with QSFP28 male connectors on both ends, this cable is suited for short-reach, high-bandwidth interconnections in data centre racks and networking equipment. The design eliminates the need for separate transceivers and patch cords, simplifying installation while maintaining electrical isolation and signal integrity for demanding InfiniBand environments.

Advantages

This 3 m AOC delivers consistent 100 Gbps throughput with low power consumption and reduced signal loss compared with copper alternatives. By using integrated optical transceivers, it reduces heat and electromagnetic interference in dense installations and ensures stable performance for latency-sensitive applications. The QSFP28 connectors provide a standardized interface for servers, switches, and routers, enabling hot-pluggable convenience and straightforward replacement when needed.

Suitable for

• High-performance computing clusters and InfiniBand fabric interconnects
• Top-of-rack and end-of-row switch-to-switch connections
• Server-to-switch uplinks in data centres
• Low-latency trading and real-time data processing environments

Key specifications

• Data rate: 100 Gbps aggregate bandwidth
• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Transmission medium: Optical fibre with integrated transceivers
• Typical use: Short-reach interconnects within racks or between adjacent racks

How to use

Install the BlueOptics QSFP28 AOC by firmly inserting each QSFP28 connector into the corresponding QSFP28 port on network switches, routers or server network interface cards. Ensure ports are compatible with QSFP28 interfaces and that devices support active optical cables. Handle the cable by the connector housings and avoid tight bends; observe the manufacturer’s minimum bend radius to prevent damage. Once connected the link should be detected by compatible devices and negotiate at 100 Gbps where supported.

Recommendations

Use this AOC for short-distance high-bandwidth links inside data centre racks. Keep the cable away from sharp edges and high-temperature components, route it to avoid pinching, and verify device firmware/driver compatibility for full 100 Gbps operation.
