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

The BlueOptics Q28-AOC-50M-SW-BO InfiniBand fibre optic cable 50m QSFP28 Male is a 50-metre active optical cable designed for high-speed data transmission between InfiniBand-enabled devices. It features QSFP28 male connectors and supports reliable, low-latency links suitable for data center backbones, high-performance computing clusters and network switches. The cable is intended to deliver consistent throughput over a 50 m distance while minimizing electromagnetic interference and heat generation compared with equivalent copper solutions.

Advantages

This 50 m QSFP28 active optical cable provides stable high-bandwidth connections with reduced signal attenuation over longer distances than copper direct-attach options. Its optical design lowers susceptibility to electromagnetic interference and supports improved thermal performance in dense rack environments. The QSFP28 interface ensures compatibility with equipment that accepts quad small form-factor pluggable 28 connectors and enables multi-lane 100 Gigabit-class links where supported.

Suitable for

• Interconnects between switches and routers in data centers
• High-performance computing (HPC) cluster node connections
• Server-to-switch links requiring low latency and high throughput
• Network fabric and InfiniBand deployments

Key specifications

• Length: 50 metres
• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Supported link: InfiniBand / high-speed Ethernet-compatible form factor
• Typical use: Data center and high-performance networking links

How to use

Install the cable by inserting each QSFP28 male connector into the corresponding QSFP28 ports on your devices, ensuring that connectors align with the port keying and secure latch. Verify port configuration and link status in device management interfaces after physical connection. No external power source is required for the cable itself, but ensure connected devices are powered and configured for the intended InfiniBand or compatible network protocol. Handle the cable by the connector housings when plugging or unplugging and avoid tight bends close to the connectors to preserve optical performance.

Recommendations

The cable performs best in structured data center environments; maintain a minimum bend radius as specified by the equipment vendor, keep connectors free of dust by using protective caps when not in use, and confirm compatibility with your QSFP28 ports and firmware to ensure expected throughput and link stability.
