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

The BlueOptics Q28-AOC-2M-IT-BO InfiniBand/fibre optic cable 2m QSFP28 Male/Male is a 2-metre active optical cable engineered for high-speed data transmission between compatible QSFP28 ports. It provides a direct optical link designed to support dense interconnects in data centres, server racks and high-performance computing setups where low latency and high throughput are required.

Advantages

This QSFP28 male-to-male cable offers a compact, lightweight design that reduces signal loss over short to medium rack distances compared to copper alternatives. As an active optical cable, it integrates optical transceivers and requires no separate SFP/QSFP modules, simplifying installation and reducing component count. The 2 m length suits standard rack-to-rack and equipment-to-equipment connections while maintaining high signal integrity and electromagnetic immunity.

Suitable for

• Interconnects between servers and switches with QSFP28 ports
• Top-of-rack and end-of-row connections in data centres
• High-performance computing clusters and storage arrays
• Low-latency InfiniBand fabrics and high-bandwidth Ethernet links

Key specifications

• Cable type: active optical cable (AOC)
• Connector type: QSFP28 male to QSFP28 male
• Length: 2 metres
• Compatible protocols: InfiniBand and high-speed Ethernet over QSFP28 form factor
• Typical use: short to medium rack distances within data centre environments
• Advantages: low signal attenuation, immunity to electromagnetic interference

How to use

Install the cable by inserting each QSFP28 male connector into the corresponding QSFP28 port on the devices to be linked, ensuring connectors are aligned and fully seated. No separate transceiver modules are required. Confirm link status on both devices after connection and check device firmware or OS for any required settings related to InfiniBand or Ethernet port configuration. To disconnect, depress the retention tab (if present) and withdraw the connector straight out to avoid bending the cable or stressing the port.

Recommendations

For reliable operation, route the cable to avoid sharp bends and maintain the minimum bend radius specified by the manufacturer. Use the 2 m length for in-rack or nearby rack connections; for longer runs, select an appropriately rated optical solution. Keep connector endfaces clean and protect them with caps when not in use to prevent contamination and ensure optimal optical performance.
