BlueOptics Q28-AOC-3M-RW-BO InfiniBand fibre optic cable 3m QSFP28 Male

The BlueOptics Q28-AOC-3M-RW-BO InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre active optical cable designed for high-bandwidth, low-latency connections between network equipment. It provides QSFP28 male-to-male connectivity and is intended for short-reach links in data centres, HPC clusters and storage networks where reliable 100Gbps-class InfiniBand links are required. The cable combines optical transmission with compact QSFP28 form-factor connectors to support dense rack deployments and reduce signal loss over short distances.

Advantages

This cable delivers high throughput and low latency suitable for InfiniBand infrastructures, using an active optical design to maintain signal integrity over three metres. Its QSFP28 male connectors enable straightforward plug-and-play installation in compatible QSFP28 ports. The optical medium reduces electromagnetic interference compared to copper alternatives and lowers power consumption for equivalent link lengths in many deployments.

Suitable for (tasks / use cases)

• Connecting QSFP28 ports between switches, servers and adapters in data centres
• High-performance computing (HPC) cluster interconnects
• Storage area networks (SAN) and high-bandwidth SAN links
• Short-reach InfiniBand links and direct server-to-switch connections

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Standard: InfiniBand-compatible 100Gbps-class links
• Length: 3 metres
• Transmission medium: Multimode optical fiber with integrated transceivers
• Typical use: Short-reach, high-bandwidth interconnects

How to use

Ensure both devices have compatible QSFP28 ports and that firmware or driver requirements for QSFP28/AOC modules are met. Align the QSFP28 male connectors with the device ports and insert until the latch engages; repeat for the other end. After connection, verify link status through device management interfaces and monitor for proper data rates and error counters. For removal, disengage the latch and pull straight out to avoid stress on the connectors.

Recommendations

Use the cable within recommended bend radius limits and avoid excessive pulling or twisting. Keep optical connector interfaces clean and protect connectors with dust caps when not in use. Install in an environment with appropriate airflow and temperature control to maintain optical component reliability.
