BlueOptics MCP7F00-A003R30L InfiniBand optický kábel 3 m QSFP28 4xSFP28 čierny

The BlueOptics MCP7F00-A003R30L InfiniBand fibre optic cable is a 3 m male-to-male assembly with a QSFP28 connector on one end and four SFP28 connectors on the other. Engineered for high-density networking and high-speed interconnects, this cable supports reliable data transmission with reduced insertion loss and stable signal integrity, making it suitable for modern data center environments and server-to-switch connections.

Advantages

This cable provides a compact multi-lane interface that simplifies connections between QSFP28 ports and multiple SFP28 ports, reducing the need for separate breakout modules. Its optical construction offers low latency and immunity to electromagnetic interference, while the 3 m length balances reach and cable management within racks and equipment cabinets. The male-to-male configuration ensures compatibility with standard QSFP28 and SFP28 ports.

Suitable for

• Connecting QSFP28-equipped switches to multiple SFP28 server ports
• High-speed InfiniBand fabric links in data centers
• Top-of-rack and end-of-row network configurations
• Low-latency computing clusters and HPC interconnects

How to use

Align the QSFP28 plug with the target QSFP28 port and insert firmly until the connector latch engages. Connect each SFP28 plug to the corresponding SFP28 ports on the target devices, ensuring proper orientation and secure seating. Verify link status indicators on connected devices after installation. For best performance, avoid tight bends, excessive pulling, and sharp kinks; route the cable following rack and cable management practices to prevent damage and maintain optical performance.

Recommendations

Use this 3 m breakout cable in short-reach high-speed links inside racks or between adjacent equipment cabinets. Keep bend radius within manufacturer guidelines and avoid exposing connectors to dust by using protective caps when not connected. Confirm port compatibility and transceiver support in your hardware before deployment to ensure expected throughput and link stability.
