## Summary description

The BlueOptics QSFP28-DAC-5M-CN is a 5-meter InfiniBand/fibre optic cable with QSFP28 connectors. It features a male/male configuration, ensuring high-speed data transmission for data centers and networking applications.

## Long description

The BlueOptics QSFP28-DAC-5M-CN is a 5-meter direct-attach cable with QSFP28 connectors designed for high-speed InfiniBand and data center interconnects. This male-to-male copper/active optical assembly supports short-reach connections between switches, servers and storage units where QSFP28 ports are standard. The cable is intended for rack-to-rack and intra-rack links that require reliable 100 Gigabit-class throughput and low latency.
Advantages
The QSFP28-DAC-5M-CN offers a compact, factory-terminated solution that eliminates field termination and reduces installation time. Its QSFP28 male connectors provide consistent electrical/mechanical contact and compatibility with QSFP28 ports. The 5 metre length balances flexibility and signal integrity for short-distance links, while the cable construction supports stable high-bandwidth transmission with reduced crosstalk and interference compared to unshielded alternatives.
Suitable for
Rack-to-rack connections in data centers
Server-to-switch links where QSFP28 ports are available
High-performance computing clusters using InfiniBand
Short-reach optical/copper interconnects in network racks
Key specifications
Connector type: QSFP28 male to QSFP28 male
Length: 5 metres
Application: InfiniBand and 100 Gigabit-class interconnects
Suitable link type: short-reach direct-attach (copper or active optical assembly)
Typical use: rack-to-rack and intra-rack high-speed data links
How to use
Install the QSFP28-DAC-5M-CN by inserting each QSFP28 male connector into the corresponding port on devices with QSFP28 interfaces. Ensure both devices are powered down or that hot-plug procedures for the equipment are followed according to manufacturer guidelines. After physical installation, verify link status through device management interfaces and check for correct speed and lane negotiation. Avoid sharp bends and maintain the specified minimum bend radius during routing to preserve signal integrity.
Usage recommendations
For optimal performance, route the cable away from high-power electrical sources and maintain proper airflow in rack assemblies. Use this 5 m QSFP28 cable for short-distance links inside racks or between adjacent racks; for longer spans, consider alternative transceiver and fiber solutions. Inspect connectors before insertion to prevent contamination and ensure reliable contact.
