BlueOptics Q28-AOC-3M-F5-BO InfiniBand/fibre optic cable 3m QSFP28 Male/Male

The BlueOptics Q28-AOC-3M-F5-BO InfiniBand/fibre optic cable is a 3-meter active optical cable with QSFP28 male connectors on both ends. It is engineered for high-speed data transmission between networking equipment and servers in data centers, high-performance computing clusters, and storage networks. The cable supports reliable signal integrity over a short-reach link while reducing electromagnetic interference compared with copper alternatives.

Advantages

This QSFP28-to-QSFP28 active optical cable provides high bandwidth and low latency suitable for 100GbE and InfiniBand environments. The 3 m length balances flexibility and signal quality for rack-to-rack or in-rack connections. As an optical solution, it offers improved thermal behavior and reduced weight compared with equivalent copper assemblies, and its male/male configuration simplifies direct device-to-device connections without separate transceivers.

Suitable for

• Interconnects between QSFP28 ports in data center switches and servers
• High-performance computing (HPC) clusters requiring InfiniBand links
• Storage area networks and aggregation links in rack environments
• Short-reach connections where reduced electromagnetic interference is required

Key specifications

• Connector type: QSFP28 male to QSFP28 male
• Cable type: Active optical cable (AOC)
• Length: 3 meters
• Data rate: Designed for 100 Gbps class applications and compatible InfiniBand speeds
• Transmission medium: Multi-mode optical link suitable for short-reach data center connections
• Form factor: Compact QSFP28 module housing for high-density installations

How to use

Insert each QSFP28 connector into the corresponding QSFP28 port on your networking equipment or server until the connector latches. Ensure both devices are powered down or support hot-plugging according to their documentation before connecting. After installation, verify link status via device management interfaces and configure ports for the required speed and protocol (for example, 100GbE or InfiniBand settings) as needed.

Recommendations

For optimal performance, route the cable to avoid sharp bends and maintain minimum bend radius specified by the manufacturer. Use this 3 m AOC for short-reach connections inside and between racks. Verify compatibility with your switches and host cards regarding QSFP28 optical modules and supported data rates prior to deployment.
