BlueLAN NVIDIA Compatible 400G QSFP-DD Breakout DAC Cable 1m Passive Copper 400GBASE-CR8 to 2x200GBASE-CR4 QSFP56

The BlueLAN 980-9IA3S-00W001-BL is a high-performance passive copper Direct Attach Cable (DAC) designed for breakout applications in modern data centers. It connects a 400GBASE-CR8 QSFP-DD port to two 200GBASE-CR4 QSFP56 ports, enabling efficient aggregation and flexible network architecture. With a length of 1 meter and ultra-low power consumption, this cable is ideal for short-reach, high-speed interconnects within racks.

Advantages

This breakout cable offers a cost-effective and power-efficient solution for splitting a 400G link into two 200G links, maximizing port utilization and reducing cabling complexity. The passive copper design ensures zero power consumption and minimal latency, while the robust construction guarantees reliable signal integrity. Compatibility with NVIDIA (Mellanox) equipment ensures seamless integration into existing infrastructures.
