## Long description

The BlueOptics QSFP28-DAC-3M-VA is a 3-meter passive direct attach copper (DAC) cable with QSFP28 connectors on both ends, engineered for high-speed 100GbE interconnects. Designed for short-reach links inside racks and across adjacent racks, the cable delivers low-latency, energy-efficient connectivity suited to data center top-of-rack and switch-to-server links. The QSFP28 form factor ensures compatibility with equipment that supports QSFP28 interfaces and passive copper twinax solutions.
Advantages
This passive QSFP28 DAC cable provides a cost-effective and power-efficient alternative to optical transceivers for short distances. The fixed 3 m length simplifies cable management while maintaining consistent signal integrity and low insertion loss. With industry-standard QSFP28 connectors, the cable supports reliable high-bandwidth transmission and reduces system power consumption compared with active or optical links.
Suitable for
 Short-reach 100GbE connections between switches and servers
 Top-of-rack and end-of-row data center cabling
 High-performance computing clusters requiring low latency
 Network equipment with QSFP28 ports supporting passive DACs
Key specifications
 Cable type: Passive direct attach copper (DAC)
 Connector type: QSFP28 male to QSFP28 male
 Length: 3 meters
 Supported data rate: 100 Gbps (QSFP28)
 Cable color: Blue
 Application: Short-reach rack and inter-rack connections
How to use
Install the QSFP28 connectors into compatible QSFP28 ports on source and destination devices, ensuring proper alignment until each connector locks into place. Use the cable for direct links within the same rack or between adjacent racks, avoiding tight bends and excessive stress on the cable assembly. Verify link status and data rate on connected devices and consult equipment documentation for any required port configuration or firmware settings.
Usage recommendations
For reliable operation, route the cable to prevent sharp bends and secure it to avoid tension. Use passive QSFP28 DACs like this 3 m cable where short-distance, high-throughput, low-power connections are required; for longer runs consider active copper or optical transceivers. Confirm compatibility with your switch or server vendor to ensure supported link speeds and to validate any vendor-specific requirements.
