BlueLAN QDD-4ZQ100-CU2M-BL Cable DAC Breakout 400G QSFP-DD a 4x100G QSFP56 2 m

The BlueLAN QDD-4ZQ100-CU2M-BL is a high-performance passive Direct Attach Copper (DAC) breakout cable designed for 400GBASE-CR4 to 4x100GBASE-CR connectivity. It connects a QSFP-DD port to four QSFP56 ports, enabling cost-effective and low-latency data center interconnects. With a length of 2 meters and AWG26 construction, this cable is ideal for short-range high-speed links within racks or adjacent racks.

Advantages

This breakout cable offers significant advantages over active optical cables: lower power consumption, no need for external power, and reduced cost. It provides reliable 400G to 4x100G breakout connectivity, simplifying network upgrades and reducing cable clutter. The passive design ensures zero latency and high signal integrity.
