## Summary description

The BlueOptics QSFP28-DAC-3M-BC is a 3-meter InfiniBand fibre optic cable with QSFP28 male connectors. It is designed for high-speed data transmission in data centers and networking environments, ensuring reliable connectivity and performance.

## Long description

The BlueOptics QSFP28-DAC-3M-BC InfiniBand fibre optic cable 3m QSFP28 Male is a 3-metre direct attach cable designed to provide reliable, high-speed connectivity between QSFP28 ports in server, switch and storage environments. Intended for short-reach interconnects, this cable supports high-bandwidth InfiniBand links with QSFP28 male connectors at both ends, offering a compact and low-latency physical connection for data center and networking infrastructures.
Advantages
This QSFP28 direct attach cable combines a slim, flexible design with QSFP28 male connectors to facilitate easy routing in dense racks and tight spaces. The 3 m length balances reach and signal integrity for short-distance links without active components, resulting in predictable latency and reduced power consumption. Its construction is focused on mechanical durability and consistent electrical performance required for InfiniBand high-speed links.
Suitable for
 Interconnecting QSFP28 ports on switches and routers within the same rack or adjacent racks
 Linking servers to top-of-rack switches in data centres
 High-bandwidth InfiniBand fabrics used for HPC and storage clusters
 Short-reach connections where low latency and high throughput are required
Key specifications
 Cable type: QSFP28 direct attach (passive) twinax/optical-style assembly for short-range InfiniBand links
 Connector type: QSFP28 male at both ends
 Length: 3 metres
 Application: High-speed data centre interconnects and InfiniBand fabrics
 Performance: Designed for 100 Gbps-class QSFP28 links with low latency characteristics
 Physical attributes: Slim form factor suitable for dense cabling environments
How to use
Install the 3 m QSFP28-DAC cable by inserting each QSFP28 male connector into the corresponding QSFP28 port until the connector latches. Ensure both devices are powered down or that hot-plug support is enabled according to your equipment documentation before insertion. Route the cable to avoid sharp bends and stress points; maintain the manufacturer-recommended bend radius. Verify link status on connected equipment and confirm that the InfiniBand link negotiates the expected speed and topology.
Usage recommendations
Use this cable for short-distance, high-throughput connections inside racks or between adjacent racks. Avoid exposing the cable to excessive mechanical strain, liquids, or temperatures outside typical data centre ranges. For longer runs or where active optical transceivers are required, choose an appropriate fiber-optic or active optical cable solution.
