BlueOptics Lenovo B4R2 Cabo Breakout Direct Attach (DAC) Compatível Passivo 200 Gbit/s para 2x100 Gbit/s Twinaxial Cobre QSFP56 para 2x QSFP56

The BlueOptics Lenovo B4R2 compatible Breakout Direct Attach Cable (DAC) is a high-performance passive twinaxial copper cable designed for 200 Gigabit Ethernet breakout applications. It connects a QSFP56 port to two QSFP56 ports, enabling efficient aggregation or splitting of data streams in data center environments. This cable is ideal for rack-to-rack and top-of-rack (ToR) connectivity, offering ultra-low power consumption and hot-pluggable convenience.

Advantages

Cost-effective and energy-efficient passive design eliminates the need for external power. Breakout configuration maximizes port utilization and reduces cable clutter. Fully compatible with Lenovo B4R2 and other QSFP56 compliant switches and NICs. Supports high-speed data transmission up to 200 Gbps aggregate (2x 100 Gbps per leg).
