## Summary description

The BlueLAN Q4S28P302.0-01P is a passive Direct Attach Copper (DAC) cable designed for high-speed data transfer. It supports 100 Gigabit Ethernet and splits into 4x25 Gigabit connections, making it ideal for connecting hardware in racks and across adjacent racks. With a length of 1 meter, this cable ensures reliable performance and efficient data transmission in data centers and networking environments.

## Long description

The BlueLAN Q4S28P302.0-01P QSFP28 to 4xSFP28 passive Direct Attach Copper (DAC) cable provides a 100 Gigabit Ethernet uplink that splits into four independent 25 Gbps channels. With a 1 meter length, this cable is designed for short-reach, high-density interconnects in rack and adjacent-rack environments, delivering low latency and consistent signal integrity for top-of-rack switches, servers and aggregation devices.
Advantages
This passive DAC cable offers low power consumption, reliable channel splitting into four 25 Gbps links and minimal insertion loss compared with active alternatives. The integrated QSFP28 to 4xSFP28 design simplifies cabling between equipment with different port types while keeping cost and complexity down. Its 1 m length reduces signal degradation for high-speed transmissions and fits typical rack layouts where devices are placed close together.
Suitable for
 Top-of-rack switch to server connections in data centres
 Inter-rack connections between adjacent racks
 High-density switch aggregation and spine-leaf architectures
 Short-reach 100G links that require breakout to 4x25G endpoints
Key specifications
 Connector type: QSFP28 (one end) to 4 × SFP28 (other end)
 Data rate: 100 Gbps aggregate, 4 × 25 Gbps channels
 Cable type: Passive Direct Attach Copper (DAC)
 Length: 1 m
 Intended reach: short-reach rack and adjacent-rack interconnects
 Latency: low, suitable for high-performance switching environments
How to use
Install the cable by inserting the QSFP28 connector into the 100G port on your switch or host device and plug the four SFP28 connectors into the corresponding 25G ports on target devices. Ensure both ends are fully seated until the retention latches engage. Use the cable for direct attachments between devices in the same rack or adjacent racks; avoid routing the cable through long cable trays or across large distances beyond its 1 m rating. Verify link status on your devices and, if necessary, configure port speeds and breakout settings in the switch or host firmware to enable 4×25G operation.
Usage recommendations
Handle the DAC cable by the connector housings and avoid excessive bending or pulling on the cable assembly. Keep the cable within its specified bend radius and away from heat sources. Confirm compatibility of the host ports with passive QSFP28 to 4×SFP28 breakout cables and check firmware or vendor notes for any required breakout configuration before deployment.
