BlueLAN QSFP28 to 4xSFP28 Passive Breakout Direct Attach Cable (DAC) 2m - Compatible with Siemon Q4S28P302.0-01P

The BlueLAN QSFP28 to 4xSFP28 Passive Breakout Direct Attach Cable (DAC) is a high-performance twinaxial copper cable designed for 100 Gigabit Ethernet connectivity. It breaks out a single QSFP28 port into four SFP28 ports, enabling efficient 100G to 4x25G connections in data centers and rack-to-rack environments. This passive DAC is fully compatible with Siemon Q4S28P302.0-01P equipment, ensuring seamless integration and reliable data transmission.

Advantages

Cost-effective and low-power solution for high-speed networking. The passive design consumes less than 0.5W, reducing overall power consumption in the data center. Hot-swappable connectors allow for easy installation and maintenance without network downtime. The breakout configuration maximizes port utilization and simplifies cable management.
