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

The BlueOptics Q28-AOC-15M-SP-BO InfiniBand fibre optic cable 15m QSFP28 Male/Male is a 15-metre active optical cable designed for high-speed, low-latency connections in data centers and professional networking environments. It uses QSFP28 connectors in a male-to-male configuration to provide a direct, compact link between compatible InfiniBand or Ethernet QSFP28 ports. The cable supports high bandwidth transmission over an all-optical link, reducing electrical interference and heat compared with copper alternatives.

Advantages

This active optical cable delivers high data throughput with low signal loss over its 15 m length. The QSFP28 connector format ensures compatibility with modern 100GbE and InfiniBand ports that accept QSFP28 modules, while the optical construction minimizes electromagnetic interference and supports a stable connection in dense rack environments. The plug-and-play design simplifies installation, and the lighter weight and flexibility of the optical cable improve cable management compared to equivalent copper assemblies.

Suitable for

• Interconnects between servers, switches and storage in data centers
• High-performance computing (HPC) clusters using InfiniBand
• 100GbE networking links and aggregation ports
• Short- to mid-range optical links within equipment racks or between adjacent racks

Key specifications

• Cable type: Active Optical Cable (AOC)
• Length: 15 metres
• Connector type: QSFP28 male to QSFP28 male
• Interface: InfiniBand and compatible QSFP28 ports (also used for 100GbE)
• Transmission medium: multimode optical link
• Characteristic: Low latency, high bandwidth, immunity to electromagnetic interference
• Form factor: Compact QSFP28 housing suitable for high-density ports

How to use

Inspect the QSFP28 connectors and port interfaces for damage or contamination before installation. Align the QSFP28 connector latches with the device port and insert the connector straight into the slot until the latch engages. Use one end of the cable to connect the first QSFP28 port and the other end to the target QSFP28 port on the second device. Ensure devices are powered and configured to recognize the optical link; the link will typically be negotiated automatically when both ports support compatible speeds and protocols.

Recommendations

Avoid tight bends and excessive pulling force on the cable; maintain the manufacturer’s minimum bend radius for active optical cables. Route the cable to reduce stress on connectors and keep it clear of hot airflow paths inside racks. For best results in high-density deployments, label both ends of the cable and document port mappings to simplify maintenance and troubleshooting.
