BlueOptics Q28-AOC-15M-PA-BO InfiniBand fibre optic cable 15m QSFP28 Male

The BlueOptics Q28-AOC-15M-PA-BO InfiniBand fibre optic cable 15m QSFP28 Male is a 15-metre active optical cable engineered for high-speed, low-latency data transmission in data centre and high-performance computing environments. Equipped with QSFP28 connectors on both ends, this cable supports InfiniBand links between switches, servers and storage systems while minimising signal loss and electromagnetic interference. The single-cable solution simplifies rack connectivity and helps maintain consistent throughput over short to medium interconnect distances.

Advantages

This active optical cable provides high bandwidth and stable signal integrity for InfiniBand applications, reducing the need for transceivers and separate fibre patching. Its 15 m length offers flexibility in rack and aisle layouts without compromising performance. The QSFP28 connector format ensures compatibility with devices that accept QSFP28 InfiniBand ports, and the optical transmission reduces susceptibility to electrical noise compared with copper alternatives.

Suitable for

• Connecting QSFP28 ports between switches in data centres
• Linking servers and storage arrays in high-performance computing clusters
• Short- to medium-range inter-rack or intra-rack InfiniBand connections
• Environments where low latency and high throughput are required

Key specifications

• Connector type: QSFP28 male on both ends
• Length: 15 metres
• Transmission medium: active optical cable (AOC)
• Supported interface: InfiniBand high-speed links
• Typical use: short- to medium-range data centre interconnects

How to use

Install the cable by seating each QSFP28 connector firmly into the corresponding QSFP28 port until the latch engages. Ensure both connected devices are powered down or follow hot-plug procedures recommended by the device manufacturers. Verify link status through the device management interfaces after connection. Route the cable to avoid tight bends and mechanical strain; maintain a gentle bend radius consistent with optical cable handling guidelines. If the link does not establish, reseat connectors and check device port settings and compatibility.

Recommendations

Use this cable within data centre racks and structured cabling paths where its 15 m length provides the required reach. Avoid sharp bends and excessive pulling force. For optimal performance, pair with devices that explicitly support QSFP28 InfiniBand AOC connections and monitor link status and error counters regularly as part of routine infrastructure maintenance.
