BlueOptics Q28-AOC-1M-QL-BO InfiniBand fibre optic cable 1m QSFP28 Male/Male

The BlueOptics Q28-AOC-1M-QL-BO InfiniBand fibre optic cable 1m QSFP28 Male/Male is a 1-metre active optical cable designed for high-speed interconnects. It uses QSFP28 connectors to deliver low-latency, high-bandwidth links suitable for data centre racks and high-performance computing networks. The cable supports compact, direct connections between QSFP28 ports, combining the signal integrity of optical transmission with the convenience of a fixed-length assembly.

Advantages

This QSFP28 active optical cable provides high data throughput and reduced electromagnetic interference compared with copper alternatives. Its 1-metre length offers predictable signal performance with minimal insertion loss for short-range links inside racks or between adjacent equipment. The male-to-male QSFP28 terminations ensure straightforward installation into compatible ports without the need for separate transceivers, simplifying deployment and reducing component count.

Suitable for

• Short-reach connections between QSFP28-equipped switches, routers and servers in data centres
• High-performance computing clusters requiring low-latency InfiniBand links
• Top-of-rack to adjacent-rack fibre interconnects where 1 m length is appropriate
• Environments where optical links are preferred to reduce EMI and improve signal integrity

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 1 metre
• Interface: InfiniBand / QSFP28 high-speed interface
• Performance: Designed for high-bandwidth, low-latency data transmission
• Usage environment: Data centre and high-performance computing applications

How to use

Install the cable by inserting each QSFP28 male plug into the corresponding QSFP28 port on the devices to be connected. Ensure ports are powered down or follow hot-plug guidance from the equipment manufacturer if connecting live. Verify link status via device LEDs or management software and confirm correct lane configuration and speed settings in system firmware or operating software. Handle the cable by the connector housings and avoid bending the cable sharply to maintain optical performance.

Recommendations

For reliable operation, use this 1 m QSFP28 AOC for short-range intra-rack or adjacent-rack links where an active optical connection is required. Avoid tight bends and secure the cable to prevent strain on the connectors. Check compatibility with the QSFP28 ports and InfiniBand mode of your equipment before deployment, and follow equipment vendor guidance for hot-plugging and firmware settings.
