BlueOptics Cisco QDD-2Q200-CU2M BlueLAN pasívny 400GBASE-CR8 QSFP-DD na 2x200GBASE-CR4 QSFP56 Direct Attach breakout kábel, 2m

The BlueOptics Cisco QDD-2Q200-CU2M BlueLAN passive breakout cable is a high-performance direct attach copper (DAC) solution designed for data centers and high-performance networking environments. It enables seamless connectivity between a 400G QSFP-DD port and two 200G QSFP56 ports, providing a cost-effective and low-latency interconnect for next-generation network infrastructures.

Advantages

This breakout cable offers significant advantages over traditional optical transceivers, including lower power consumption, reduced cost, and simplified cable management. The passive twinax design ensures reliable signal integrity over the 2-meter length, while the breakout configuration allows efficient utilization of 400G ports to connect dual 200G devices. It is hot-swappable and fully compatible with Cisco equipment, making it an ideal choice for upgrading or expanding network capacity.
