BlueOptics AOC-Q28-100G-2M-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male

The BlueOptics AOC-Q28-100G-2M-BO InfiniBand fibre optic cable is a 2-meter active optical cable (AOC) with QSFP28 male connectors on both ends. Designed for short-reach, high-bandwidth links, this cable supports 100GBASE-SR4 transmission over multi-mode fiber using integrated optical transmitters and receivers. It follows common QSFP28 MSA pinning and electrical/optical requirements to ensure interoperability with networking equipment that accepts QSFP28 AOC modules.

Advantages

This active optical cable offers low-latency, high-throughput connectivity for dense rack and data centre deployments while avoiding the need for separate transceivers and fiber patching. At 2 meters length it provides a compact, organized link between switches, servers, and storage systems. Built-in optical components handle serialization and deserialization required for 100GBASE-SR4 and related protocols, reducing host-side configuration and improving signal integrity over multi-mode fiber.

Suitable for

• Interconnects between QSFP28 ports in data centres and server racks
• High-performance computing clusters requiring 100 Gbps links
• Short-reach connections for switches, routers and storage arrays
• Environments using Ethernet, Fibre Channel over Ethernet, or SDH/SONET at up to 100 Gbps

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Supported data rate: up to 100 Gbps
• Transmission standard: 100GBASE-SR4 over multi-mode fiber
• Cable type: active optical cable with integrated Tx/Rx
• Length: 2 metres
• Form factor: QSFP28 AOC for short-reach interconnects

How to use

Insert one QSFP28 connector into the appropriate QSFP28 port on each device, ensuring the latch engages securely. The cable is hot-pluggable; devices typically detect the active optical link automatically and negotiate the correct 100G PHY or compatible protocol. Use proper ESD precautions when handling connectors and avoid tight bends near the connector to preserve fiber integrity. Verify device compatibility and firmware requirements before deployment to ensure full interoperability.

Recommendations

Install the cable in racks with sufficient slack to prevent strain, maintain bend radii recommended for optical assemblies, and avoid routing near high-power electrical equipment that could introduce interference. For critical installations, validate the link with the intended hardware and perform connectivity tests to confirm expected throughput and protocol operation.
