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

The BlueOptics Q28-AOC-2M-NK-BO InfiniBand/fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable engineered for high-speed links between QSFP28 ports. It supports short-reach connections in racks and between adjacent switches or servers, delivering low-latency, high-bandwidth transmission appropriate for data centers and high-performance computing installations. The male-to-male QSFP28 terminations provide a plug-and-play connection for compatible network adapters and switches.

Advantages

This QSFP28 active optical cable provides high aggregate throughput while keeping power consumption and heat generation low. Its 2 m length balances reach and cable management inside racks, reducing the need for electrical retimers and simplifying port-to-port connections. The fibre construction offers immunity to electromagnetic interference and stable signal integrity for demanding workloads.

Suitable for

• Interconnecting QSFP28 ports on switches and routers within the same rack or neighboring racks
• High-performance computing clusters requiring low-latency links
• Data centre uplinks, leaf-spine architectures, and server-to-switch connections
• Storage networks and NVMe over Fabrics deployments with InfiniBand or fibre optics

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 2 metres
• Supported interface: InfiniBand and fibre optic high-speed links
• Designed for: Multi-lane 100 Gbps-class connections (QSFP28 form factor)
• Physical feature: Lightweight, flexible optical cable suitable for dense cabling environments

How to use

Install the BlueOptics QSFP28 AOC by aligning each QSFP28 male connector with the corresponding port on your devices and inserting until the connector latches. Use the cable for direct links between compatible QSFP28 ports; no additional transceivers or patch panels are required for direct QSFP28-to-QSFP28 connections. Verify link status and speed in your host or switch management interface after installation to confirm proper operation.

Recommendations

Route the cable to avoid sharp bends and maintain the minimum bend radius recommended for optical cables. Secure the cable to prevent strain on connectors and keep it clear of high-temperature sources. Confirm compatibility with the QSFP28 ports and system firmware to ensure optimal performance.
