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

The BlueOptics Q28-AOC-50M-RW-BO InfiniBand fibre optic cable 50m QSFP28 Male is a 50-metre active optical cable designed for high-speed InfiniBand links. It features QSFP28 male connectors on both ends and supports low-latency, high-bandwidth data transmission typical for high-performance computing and dense data centre networking. The cable's length and connector type make it suitable for connecting switches, host channel adapters, and storage systems across rack and row distances.

Advantages

This active optical cable delivers high data throughput with reduced electromagnetic interference compared with copper alternatives. Its QSFP28 male terminations ensure compatibility with QSFP28 ports and enable reliable link establishment. The 50 m reach provides flexibility for larger rack layouts while keeping signal integrity and performance over the required distance.

Suitable for (tasks / use cases)

• Inter-rack and intra-rack InfiniBand connections in data centres
• High-performance computing clusters and server interconnects
• Connections between switches, storage arrays, and host adapters
• Low-latency environments that require high-bandwidth links

Key specifications

• Cable type: Active Optical Cable (AOC)
• Connector type: QSFP28 Male to QSFP28 Male
• Length: 50 metres
• Interface: InfiniBand-compatible high-speed link
• Signal: Optical (fiber) transmission for reduced EMI

How to use

Install the cable by inserting each QSFP28 male connector into the corresponding QSFP28 port on your network devices until the connector latches. Ensure devices are powered down or that hot-swap procedures for QSFP28 modules are followed according to the device manufacturer. Verify link status through your switch or host interface management to confirm proper negotiation and data rates.

Recommendations

Route the cable to avoid sharp bends and mechanical stress; maintain the manufacturer’s minimum bend radius for optical cables. Use proper labeling and documentation for long runs in rack and cable-management trays. For optimal performance, ensure connected devices support the same InfiniBand link speeds and perform firmware updates on network equipment as recommended by the hardware vendors.
