BlueOptics Q28-AOC-3M-SS-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-SS-BO InfiniBand fibre optic cable 3m QSFP28 Male/Male is a 3-metre active optical cable designed for high-bandwidth, low-latency interconnects in data centre and high-performance computing environments. With QSFP28 connectors on both ends, this cable supports high-speed links and offers a compact, lightweight alternative to copper cabling for short-reach connections where signal integrity and thermal performance are important.

Advantages

This active optical cable provides a stable high-speed data path with reduced electromagnetic interference and improved thermal characteristics compared with equivalent copper solutions. Its QSFP28 male-to-male configuration enables straightforward connectivity between compatible switches, network adapters and servers. The 3-metre length allows flexible equipment placement in racks while maintaining signal performance expected from InfiniBand interconnects.

Suitable for

• High-performance computing clusters and node interconnects
• Top-of-rack or spine-to-leaf switch connections in data centres
• Server to switch or server to storage direct links
• Short-reach, high-bandwidth network links requiring low latency

Key specifications

• Connector type: QSFP28 male on both ends
• Cable type: Active optical cable (AOC)
• Length: 3 metres
• Application: InfiniBand high-speed interconnects
• Performance: Designed for high-bandwidth, low-latency data transmission
• Physical: Lightweight, flexible optical assembly for short-reach links

How to use

Inspect both QSFP28 connectors and the cable for damage before installation. Align the connector keying with the device receptacle and insert the QSFP28 module fully until it seats and the retention mechanism engages. Ensure both connected devices are powered off or follow hot-plug procedures recommended by the equipment vendor. After connection, verify link status on network devices and configure ports according to your InfiniBand or Ethernet settings as applicable.

Usage recommendations

Route the cable to avoid sharp bends and excessive torsion; maintain the manufacturer’s minimum bend radius to preserve optical performance. Use proper cable management in racks to reduce strain on connectors and avoid proximity to strong electromagnetic sources when mixing with electrical cabling. For long-term reliability, periodically inspect connectors for contamination and clean with appropriate fibre-optic cleaning tools if required.
