BlueOptics MFA1A00-C003-BO InfiniBand fibre optic cable 3 m QSFP28 Male

The BlueOptics MFA1A00-C003-BO InfiniBand fibre optic cable 3 m QSFP28 Male is a 3-meter active optical cable (AOC) with QSFP28 male connectors designed for high-speed server, switch and storage interconnects. It supports 100G links over multimode fibre and implements both transmitter and receiver electronics integrated into the cable ends to carry optical signals in accordance with established QSFP28 and 100GBASE-SR4 interfacing practices. The cable is intended for use in data centre and high-performance networking environments where low-latency, high-bandwidth connections are required.

Advantages

The cable provides a factory-assembled AOC solution that integrates optical transceivers and multimode fibre in a single ready-to-use assembly, reducing the need for separate transceivers and patch fibres. With QSFP28 male connectors and compatibility with 100GBASE-SR4 signalling, it enables straightforward point-to-point connections between compatible QSFP28 ports while maintaining signal integrity over the 3 m span. The integrated design reduces connector losses and simplifies rack cabling compared with discrete transceiver plus patch-cable setups.

Suitable for

• 100 Gigabit Ethernet links between switches and routers
• High-performance computing and InfiniBand-compatible interconnects
• Storage area network uplinks and server-to-switch connections
• Short-reach data centre links up to 3 metres

Key specifications

• Cable type: Active Optical Cable (AOC) with integrated transmitters and receivers
• Connector type: QSFP28 male to QSFP28 male
• Nominal length: 3 metres
• Supported data rate: up to 100 Gbit/s over 100GBASE-SR4 signalling
• Fiber type: multimode fibre suitable for short-reach multimode applications
• Form factor: QSFP28 electrical/optical interface

How to use

Install the cable by aligning each QSFP28 male connector with the corresponding QSFP28 port on your network devices and gently inserting until the connector latches or seats according to the port design. No separate transceiver installation is required because the optical transceivers are integrated into the cable ends. Ensure both ends are plugged into compatible QSFP28 ports that support 100GBASE-SR4 or equivalent 100G modes. Avoid sharp bends in the cable and secure the cable to prevent strain at the connector ends.

Usage recommendations

For reliable operation, use this 3 m QSFP28 AOC in short-reach links within racks or between adjacent racks. Verify that connected devices officially support QSFP28 AOC modules and 100GBASE-SR4 signalling. Maintain proper cable bend radius, keep connector end-faces clean, and avoid exposure to mechanical stress or liquids. If interoperability is critical, test the cable in your specific hardware configuration prior to large-scale deployment.
