BlueOptics Q28-AOC-50M-AO-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male

The BlueOptics Q28-AOC-50M-AO-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male is a 50-metre active optical cable (AOC) with QSFP28 connectors on both ends. It is intended for high-speed data transmission in environments that require low latency and high bandwidth, such as data centres and high-performance computing racks. The cable provides a factory-terminated, pluggable connection that eliminates the need for transceivers in each connected port while maintaining the form factor and signal integrity suited to InfiniBand QSFP28 interfaces.

Advantages

The active optical design reduces electrical interference and supports long-reach connections within server rooms and across equipment racks without the bulk or power requirements of copper assemblies. As a QSFP28-to-QSFP28 cable, it supports the connector density and lane aggregation typical for 100 Gbps and related InfiniBand link configurations. The 50 metre length offers flexibility in equipment placement and cable routing while preserving signal quality suitable for high-throughput, low-latency links.

Suitable for

• High-performance computing clusters and node interconnects
• Data centre top-of-rack and end-of-row connections requiring ~50 m reach
• Server-to-switch and switch-to-switch InfiniBand links using QSFP28 ports

Key specifications

• Cable type: Active Optical Cable (AOC)
• Length: 50 metres
• Connector type: QSFP28 male to QSFP28 male
• Interface: InfiniBand-compatible QSFP28 form factor
• Typical use: High-speed, low-latency data links for racks and rows

How to use

Install by inserting each QSFP28 connector into the corresponding QSFP28 port on network switches, host adapters or servers. Ensure connectors are clean and free of dust before insertion; follow host and switch vendor guidelines for handle orientation and latch engagement. The active optical cable is plug-and-play in most environments that support QSFP28 AOCs, but verify supported link speeds and firmware compatibility on equipment prior to deployment. Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s recommended bend radius for optical assemblies.

Recommendations

Inspect connector endfaces before each installation and use appropriate fibre cleaning tools to prevent contamination. Avoid tight bends, excessive tension, or kinks along the 50 m length; secure the cable with suitable ties or trays to prevent movement. Confirm that connected devices support QSFP28 AOC modules and the required InfiniBand speed settings to ensure optimal performance.
