InfiniBand/fibre optic cable BlueOptics MCP7F00-A02AR30L 3 m QSFP28 4xSFP28 Black

The BlueOptics MCP7F00-A02AR30L is a 3 m InfiniBand/fibre optic cable that links a QSFP28 interface to four SFP28 ports. Designed for high-speed data transmission, this male-to-male cable supports dense interconnect topologies in data centers and high-performance networking environments. Its compact construction and standardised connectors enable straightforward integration with compatible switches, network interface cards and storage systems.

Advantages

This cable provides a single-cable solution for connecting QSFP28 devices to multiple SFP28 ports, reducing cable clutter and simplifying patching. The 3 m length balances reach with signal integrity, while the fibre optic medium offers low latency and immunity to electromagnetic interference. The durable jacket and connector assemblies are intended to maintain stable optical performance across repeated installations.

Suitable for

• High-performance computing clusters and InfiniBand fabrics
• Data centre switch-to-module and switch-to-top-of-rack connections
• Server and storage interconnects using QSFP28 and SFP28 ports
• Low-latency trading platforms and real-time data processing systems

Key specifications

• Cable length: 3 metres
• Connector types: QSFP28 to 4 × SFP28
• Configuration: male-to-male
• Transmission medium: fibre optic
• Colour: black with blue identification

How to use

Identify the QSFP28 port on the source device and the SFP28 ports on the target device or module. Align connectors carefully and insert until the latch engages to ensure a secure connection. Route the cable to avoid sharp bends and excessive tensile stress; maintain the minimum bend radius specified by system manufacturers. When removing, press the release mechanism on each connector before withdrawal to prevent damage.

Recommendations

For optimal performance, use this cable in compatible QSFP28 and SFP28 ports rated for the intended data rate, keep connectors clean and free from dust, and avoid routing near sources of mechanical stress or heat. Verify link settings and firmware compatibility on networking equipment when integrating across vendor platforms.
