BlueOptics Q28-AOC-50M-CO-BO InfiniBand optický kábel 50m QSFP28 konektor samec/konektor samec

The BlueOptics Q28-AOC-50M-CO-BO InfiniBand fibre optic cable 50m QSFP28 Male/Male is a 50-metre active optical cable designed for high-speed interconnects in data center and high-performance computing environments. Featuring QSFP28 connectors on both ends, this cable supports high-bandwidth InfiniBand links while maintaining low latency and signal integrity over a 50 m distance. The male-to-male QSFP28 form factor ensures straightforward connection between compatible ports on switches, routers, host adapters and compute nodes.

Advantages

This active optical cable combines the electrical interface of QSFP28 with optical transmission to provide long-reach, high-bandwidth connectivity without the electromagnetic interference associated with copper. The 50 m length reduces the need for intermediate patching, simplifies rack-to-rack connections and helps maintain predictable performance across larger footprints. Designed for energy-efficient operation, the cable offers consistent signal quality and reduced heat generation compared with equivalent copper assemblies.

Suitable for

• High-performance computing clusters requiring low-latency InfiniBand links
• Data centre rack-to-rack interconnects and leaf-spine topologies
• Switch-to-switch or HBA-to-switch connections over medium distances
• Storage systems and distributed compute nodes needing high throughput

Key specifications

• Connector type: QSFP28 Male to QSFP28 Male
• Length: 50 metres
• Transmission medium: Active optical cable (AOC)
• Supported protocol: InfiniBand compatible with QSFP28 electrical interface
• Performance characteristics: High-bandwidth, low-latency optical link suitable for 100Gbps-class interconnects
• Construction: Integrated transceivers and optical fibre in a single cable assembly

How to use

Install the cable by aligning each QSFP28 connector with the corresponding QSFP28 port and inserting until the connector latches. Ensure both devices are powered down or that hot-swap procedures for the equipment are followed according to the device manufacturer. Verify link status through the host or switch management interfaces and confirm the negotiated speed and link health. Route the cable to avoid sharp bends and secure it to reduce stress on connectors and ports.

Recommendations

To maintain optimal performance, avoid tight bends and kinks, keep the cable clear of heat sources and electromagnetic noise where possible, and use appropriate strain relief at connector ends. Check firmware and driver compatibility on connected devices to ensure full InfiniBand feature support and stable link operation.
