Cabo de fibra ótica InfiniBand BlueOptics Q28-AOC-50M-QN-BO 50 m QSFP28 macho

The BlueOptics Q28-AOC-50M-QN-BO InfiniBand fibre optic cable is a 50-metre active optical cable with QSFP28 male connectors, designed for high-speed data transmission in data centres and HPC environments. This cable delivers a direct, low-latency link between compatible QSFP28 ports and supports the bandwidth and signal integrity requirements of InfiniBand interconnects. The cable's 50 m length provides flexible routing options while maintaining optical performance for rack-to-rack and row-to-row connections.

Advantages

This active optical cable preserves signal quality over longer distances than copper alternatives and reduces electromagnetic interference due to its fibre optic design. QSFP28 male connectors allow plug-and-play replacement and interoperability with equipment that accepts QSFP28 interfaces. The 50-metre length offers the ability to connect distant racks or equipment without requiring additional transceivers or patch panels, while keeping latency and power consumption low compared with multi-component solutions.

Suitable for

• High-performance computing clusters and InfiniBand fabric interconnects
• Data centre rack-to-rack and row-to-row optical links
• Server-to-switch and switch-to-switch connections requiring QSFP28 interfaces

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 50 metres
• Application: InfiniBand high-speed data interconnect
• Performance: Designed for low-latency, high-bandwidth links

How to use

Insert each QSFP28 connector into compatible QSFP28 ports on networking equipment or servers, ensuring connectors are oriented correctly and latched where applicable. Route the cable to avoid tight bends and mechanical strain; follow equipment vendor guidelines for port hot-plugging to prevent link disruption. The active optical cable is typically recognised by devices that support QSFP28 AOCs without additional transceivers, simplifying deployment in existing InfiniBand fabrics.

Recommendations

For reliable operation, maintain a minimum bend radius as specified by the manufacturer, avoid exposing connectors to dust and contaminants by using protective caps when disconnected, and verify firmware and driver compatibility on connected devices to ensure optimal link negotiation and performance.
