Product Overview
The C DQ8FNMxxx N00 is a high-density direct attach cable (DAC) assembly, designed to support 400G QSFP-DD to 8x 50G SFP56 breakout configurations. This passive copper cable solution provides a cost-effective, low-latency, and energy-efficient interconnect for high-speed data center environments. It enables direct point-to-multipoint connectivity between 400G switches and multiple 50G server NICs without the need for optical transceivers.
