BlueOptics Lenovo B4QQ Cabo Direct Attach (DAC) BlueLAN Compatível Passivo 200 Gigabit Twinaxial Cobre QSFP56 para QSFP56 0,5m

The BlueOptics Lenovo B4QQ compatible BlueLAN Direct Attach Cable (DAC) is a high-performance, passive twinaxial copper cable designed for 200 Gigabit Ethernet (200GbE) connections. It features QSFP56 connectors on both ends, making it ideal for short-range, high-speed data interconnects within racks and between adjacent racks. This cable is fully compatible with Lenovo B4QQ series hardware and complies with SFF-8665 (QSFP56 MSA) and IEEE 802.3cd (200GBASE-CR4) standards.

Advantages

This passive DAC cable offers ultra-low power consumption, hot-swappable capability, and robust EMI/RFI protection through shielded twinax construction. It provides a cost-effective and reliable solution for high-density data center environments, ensuring minimal signal loss and maximum throughput.
