BlueOptics Dell EMC Compatible DAC-QSFP28-4SFP28-25G-1M BlueLAN Passive 100GBASE-CR4 QSFP28 to 4x25GBASE-CR SFP28 Direct Attach Breakout Cable, 1m, AWG26

The BlueOptics Dell EMC Compatible DAC-QSFP28-4SFP28-25G-1M BlueLAN is a high-performance passive direct attach breakout cable designed for data center and enterprise networking environments. It enables seamless connectivity between a QSFP28 port and four SFP28 ports, supporting aggregate data rates of 100 Gbps. This cable is fully compatible with Dell EMC and other standard QSFP28/SFP28 hardware, ensuring reliable and cost-effective network expansion.

Advantages

This breakout cable offers a simple, low-power solution for high-speed interconnects. Its passive copper design eliminates the need for external power, reducing overall energy consumption. The 1-meter length with AWG26 gauge provides flexibility in rack installations while maintaining signal integrity. Hot-pluggable functionality allows for easy deployment and maintenance without network downtime.

Suitable for

• Data center server-to-switch connections
• High-speed rack interconnect within top-of-rack architectures
• Upgrading existing 25G infrastructure to 100G aggregation
