BlueOptics Q28-AOC-2M-F5-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male

The BlueOptics Q28-AOC-2M-F5-BO InfiniBand fibre optic cable 2m QSFP28 Male/Male is a 2-meter active optical cable designed for high-speed InfiniBand connections. It features QSFP28 connectors on both ends and is intended for direct, short-reach links between servers, switches and host channel adapters in data centres and high-performance computing clusters. The cable supports low-latency, high-bandwidth transmission while maintaining electrical isolation and reduced electromagnetic interference compared with copper alternatives.

Advantages

This InfiniBand fibre optic cable provides high throughput and low latency for demanding network environments. The QSFP28-to-QSFP28 male configuration enables straightforward direct-attach connections without additional transceivers. The 2 m length offers a practical balance between reach and signal integrity for rack-to-rack and intra-rack cabling. Built as an active optical cable, it reduces heat and power consumption compared with equivalent copper assemblies and helps maintain stable performance in dense installations.

Suitable for

• Direct connections between QSFP28 ports on switches and servers
• High-performance computing (HPC) clusters
• Data centre top-of-rack and middle-of-row links
• Low-latency storage area network (SAN) and database interconnects

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Link type: Active optical cable (AOC)
• Length: 2 metres
• Supported interface: InfiniBand (compatible with QSFP28 ports)
• Performance characteristics: high bandwidth, low latency, optical transmission
• Physical attributes: lightweight, flexible cable assembly for short-reach connections

How to use

Ensure both devices have compatible QSFP28 ports and that any port modules are powered down following the equipment manufacturer's guidelines before insertion. Align the QSFP28 connectors with the port openings and insert fully until the latch engages; confirm a secure mechanical connection. After installation, verify link state and configuration via the host or switch management interface. For removal, follow the reverse procedure, disengaging the latch and pulling the connector straight out to avoid bending the cable excessively.

Recommendations

Install and route the cable to avoid tight bends and crushing; maintain the minimum bend radius specified by the equipment manufacturer. Use proper port compatibility checks and firmware that supports QSFP28 AOC devices. For optimal thermal and signal performance, avoid coiling the cable tightly and keep it clear of high-heat sources and sharp edges.
